Bruce’s (Snowy?) Weather Brief – December 3-4 and Winter Vashon Race

So while the weather wonks have gotten us all wound up about the possibility of snow on Saturday night, Sunday night, and Monday morning, we’re just happy there’s a great possibility of wind for TYC’s Winter Vashon Race on Saturday. Currently (1300 hrs Friday), There’s plenty of breeze from West Point north so if you’re doing the delivery south to Tacoma, it’s really not going to be too bad. Plus, there was certainly a great party last night at TYC. It’s today that could be very entertaining.

(Editors Note: This is getting out late – early Saturday morning – so be sure to spread the word that Bruce’s words of wisdom are here for the taking)

It’s interesting that none of the models can really agree on what’s going to happen this weekend. While snow is good for headlines and readership, reality may be quite different. No question, it’s going to get colder over the next couple of days but measurable snow in the lowlands? I’m not so sure about that.

As you can see from the surface chart today we’ve got another monster low up in the Gulf of Alaska with an attached front aimed right at the coast from Seward south to Crescent City. This will blow thru today and leave us with a direct onshore flow for the weekend which bring moisture in from the Pacific to meet up with cold air that will be moving south from the interior of Canada. Yes, excellent conditions for snow, however they do have to be perfect for snow to occur in the Puget Sound area.

The best part of this is that it really does look like wind for tomorrow. Not too much to make it uncomfortable and as long as you finish before it about 1900 hours tomorrow night it should be a fairly consistent 5-15 knots of south-southwesterly breeze in the morning that may bump up slightly to 10-20 from the SW in the afternoon.

What does this mean for the race course? Actually there should be some wind, even in Colvos and not like last year’s drag racing from hole to hole, but we’ll see. As always the current will be going the right direction however there are rivers of current in Colvos so you’ll want to watch the COG and SOG to see if you can stay in the axis of the current. (The NOAA current predictions are here – look for Anderson Point) The breeze will be coming in from the coast so it will be puffy and shifty from the southwest in the Passage so watching the fleet will be key. Remember also that out of the 65 boats entered, there are 18 in the Cruising and Commodore Classes that will be starting about 30 minutes ahead of the PHRF fleet and there are some excellent sailors in those early starting classes.

You’ll be starting just before max ebb at the Narrows so the usual rules apply; get west as fast as you can from the start fighting to stay in clear air. Don’t get too close to the bottom end of Vashon and remember that stronger current at the bottom end of Colvos is on the west side.

As the puffs come across Colvos Passage you’ll want to soak down after the puff has hit and your speed starts to build, don’t soak down to fast. Stay in the puff and don’t get too close to the Vashon shore as the puff will lift off the water as it approaches the Island.

As you approach the turning mark off the north end of the Island, don’t mess with the ferries, and be ready for a long starboard tack to Point Robinson, visibility may be low so know the compass course to Point Robinson and don’t sail too far above rhumb line because there will be less wind closer to Vashon. Also have you’re barber hauler rigged for starboard tack since it will probably get more reachy the closer you get to Point Robinson and the further away from the Island you get.

From Point Robinson to the finish it should be an almost dead beat. Slack tide is around 1430 hours going to a max flood around 1630 hours. With days of southerly wind, there won’t be much help in the flood. It will however be more sloppy choppy out in what flood there is. Since the breeze is liable to be more from the southwest, you’ll want to tack towards the Island once you are south of Robinson . just don’t get in too close. When you are on starboard tack, the puffs will be lifts, the water will be smoother and you should gain on the boats that stay too far out.

Know precisely where the finish line and remember that in the southwesterly, you’ll be lifted as you come across Dalco and the current normally flows to the northwest along the slag pile.

Then there’s the delivery back to Seattle. Remember I mentioned it was going to get colder on Sunday. That’s because there will be a cold breeze coming down out of the Canadian interior right down into the Pacific Northwest which will mean a 15-20 knot northerly until late in the afternoon on Sunday. Perfect if you have to deliver the boat south to Olympia, not so good for going north to Seattle or Everett.

Have a great weekend and be safe out there.

Bruce’s Brief: Weekend Weather Nov 19-20 Including CYC Turkey Bowl

Just looking at the surface charts for this weekend you would think that this should be just about the perfect weekend for the Laser Districts/Turkey Bowl and with 22 boats registered, it’s looking pretty great!

The interesting part is that the models are still not in agreement over what will happen on Saturday, at least for central Puget Sound. In the Straits they do agree it’s going to be breezy from east-southeast almost all weekend. As you can see from the surface charts and 500 MB charts there is a very healthy low pressure system that is just sitting off the coast and not going anywhere. It will continue to sit there and just spin off frontal systems which will mean rain and showers for at least the next five days. By Sunday the system will have moved slightly closer to the coast so this will probably the best day for steady breeze from the south in the 10-20 knot range.

Saturday will start out with fairly good breeze however it will get a bit light and shifty in the afternoon before it starts to settle back in from the south which should occur sometime early Saturday evening. As they say, conditions will provide something for everyone.

Tides are interesting in that you’ll be sailing in a fairly continuous ebb almost all day both days.

Saturday

0800      Slack

0924      .34 knot                 Ebb

1112      .26 knot                 Ebb

1300      .31 knot                 Ebb

1506      Slack

1730      .62 knot                 Flood

Sunday

0900      Slack

1042      .26 knot                 Ebb

1300      .26 knot                 Ebb

1554      Slack

1830      .6 knot                    Flood

Remember that with a continuous southerly today and rain starting this evening the ebb will start sooner by 30-45 minutes and last longer by the same amount. There will also be some freshwater rivers on top of the saltwater of the Sound that will be interesting to deal with. Once again it will pay to keep your head out of the boat and watch what’s going on around you. At least with a southerly and an ebb, the water should stay relatively flat.

Sailing off of Shilshole depending upon where the course is set you may still be able to get close enough to the beach to take advantage of the port tack puffs which will be lifts the closer in you can get. On the runs watch for the puffs coming out of the Locks and remember that these puffs tend to fan out the further away from the Ship Canal they get.

Have a great weekend, be safe, it will be wet but really, really fun!

Bruce’s Brief: Salish Sea Weather for November 12-13

Bruce’s Brief: Salish Sea Weather for November 12-13

Well, it certainly has been an interesting week! Plus the weather has been its usual interesting self as well with the possibility that we’ll break the record for consecutive days over 60⁰ in November. Record high temperatures in the Midwest and Eastern US, latest time for no temperatures below freezing, the list goes on and on. Now the wags are talking about a La Niña winter. This usually means a wetter and cooler than “normal” whatever that is. As we say however, it’s what’s in Nature that’s real. So we’ll just keep looking at the weather models and try to figure more ways to go boating this time of the year because now is a GREAT time to go boating. The weather can be beautiful and the anchorages are pretty much empty. We do however have to watch the weather a little closer as this is the time of cold fronts, small craft and gale warnings. Much like this weekend.

The Friday chart looks pretty innocuous with five low pressure systems in the Pacific and a cold front headed right at us. The leading edge of which is currently showing up on the Doppler radar. The Saturday morning chart shows the front ever closer which means increasing wind over the area.

The Sunday morning chart shows an even more intense system approaching the coast with four pretty healthy low pressure system in the Gulf of Alaska just getting ready to send more fronts our way. The Tuesday morning surface chart is even more interesting as it appears there will be an endless succession of lows headed into the Pacific Northwest and maybe even northern California which as always, could use the rain. A look at the 500 MB charts shows why this will be pretty relentless since the jet stream is aimed right at us.

So yes, you can go cruising or you can just go down to the marina, take care of some winterizing chores and spend the weekend on the boat reading all those owner’s manuals that you promised yourself you’d get around to eventually. Regardless, always check the VHF for current conditions and plot the barometric pressure. If you have wifi on the boat check the graphs on the NDBC web sites that track wind speed and barometric pressure tendencies. Whatever you do, don’t put yourself, your crew or your boat in harm’s way by taking unnecessary chances.

Enjoy the weekend!

 

Bruce’s Brief November 5-6 including Round the County!

Bruce’s Brief November 5-6 including Round the County!

No question, fall is here and it’s time for one of the most challenging and consequently one of the most popular races in the Pacific Northwest, Round The County. It’s not easy to get there and it won’t be easy to get home from if your homeport is somewhere other than Anacortes. Details.

It may be gorgeous today but after having had the wettest October in history, 9.8 inches of rain compared to a normal 3.25 inches, we can probably expect more of the same for November, our traditionally wettest month. So if you liked October, you’re going to love this Saturday!

As you can see from today’s surface chart and the Saturday AM chart we have a fairly active front headed towards us on Saturday. Start logging your barometer readings when you get to the boat today. The problem will be that after the start (0830±) when the front passes and the barometer starts up, the breeze will drop the closer you get to the finish on the west side of San Juan Island. All of this will be compounded by the tidal currents, so let’s start with a known and then we’ll get the dartboard out.

*And yes, I know that with the tides in the Pacific Northwest it’s supposed to be an hour later just remember that we change over to Pacific Standard Time at 0200 hrs Sunday morning.

So right now it looks like breeze for the start, with about 2 knots of tide right on the nose. You’ll want a safe starboard tack start trying to leave yourself a opening so you can tack to port and get headed to some tidal relief along the Blakely Island shore. You’ll short tack your way south watching your COG and SOG. After you’ve hit the anti-water don’t spend a lot of time waiting to tack back to port to get back to the beach. This will all be very interesting because of the reverse start. You’ll have to be constantly thinking two to four tacks ahead so you can find your clear air lanes to work your way south to Davidson Rock. Also, if you’re starting with a #1, think about having it in the port groove so if you have to change down you’ll hoist the #3 on starboard tack and then tack change back to port.

Once you’re at Davidson Rock it will be time to crack off and head towards the halfway mark at Salmon Bank where you must call in your time. So before the start have your barber hauler line rigged for port tack so you won’t have to have too many people off the rail when you decide to reach off. The sprit boats will be able to set sooner than the S-sail boats so you will need to know when you can set. After the mark at Salmon Bank the breeze will begin to back off and you’ll start seeing tide against you if you are too far off the beach. This will be another case where it will be super important to have your head out of the boat and use the boats around you to help guide you up to the finish. The problem here is that there is a back eddy that runs north up the beach from Salmon Bank almost all the way to the Lime Kiln light so you’ll want to ride that as long as you can as the breeze starts to drop and the ebb begins to build against you offshore. There will also be less wind the closer you get to San Juan Island so you’ll be working hard to find that happy medium between less wind and positive water.

As you approach the finish in light air be sure to have your #1 tee’d up and ready to hoist as the breeze can get very shifty in close to the finish. Just remember last year’s start on Sunday. Try to be finished before about 1400hrs on Saturday.

Sunday looks like a pretty nice day for a race as you’ll transition from the post frontal southwesterly in the start to a the pre-frontal southeasterly for the beat from Patos to the finish. Expect the breeze to build from the southeast from about 1400 hours on and make sure your navigator knows which buoys and rocks you have to leave to starboard.

The start will be downwind which will make finding clear air a challenge, that’s the bad news. The good news is that you’ll have the tide with you, just don’t sail too many extra miles to get outside into the stronger tide. As you get to Turn Point don’t cut it too close as there is a distinct light spot in the lee of the Island immediately after the Point, that runs almost the entire length of Stuart Island.. If you get into the light air, it can be a painful gybe to get back out into the breeze. Again, knowing the compass course to Alden Point and sticking to it will be a help. Some boats will tend to hold to the south of the rhumb line, you’re better off to sail the shortest possible course.

After Patos you’ll probably have the tide with you for the beat to Lawrence Point on Orcas Island. It will be long port tacks and short starboard tacks as the water will be smoother closer to the islands. Make sure you have your barber hauler set-up for port tack when you get to Lawrence Point for the reach to the finish. There will be better tide outside of the Peapod Rocks however it’s a shorter distance to sail between Orcas and the Peapods to the finish. If the prefrontal breeze isn’t fully developed there can also be less wind in there.

Then there’s the trip home after the Race. If you’re down from Vancouver, no problem. As long as you’re ready to sail in 25-30 knots of southeasterly. If you have to travel south on Sunday night, the east end of the Straits of JdF will be rough. If you can travel under the Rainbow Bridge in La Conner, go to La Conner, spend Sunday night and then leave at first light on Monday. The breeze will stay out of the southeast at 10-15 for most of Monday and Tuesday before it gets light, less than 10 knots, for late Tuesday, through Wednesday and into Thursday. Thursday afternoon the next front be approaching.

Have a great race and be safe.

 

Ed. Note: Once again we’re indebted to Bruce Hedrick for this info. And he isn’t even sailing this year! I’ll write up an account of the race early next week from my view aboard Brian Duchin’s and Kelsey Sheldon’s J/133 Tango.

 

 

 

Bruce’s Brief – Grand Prix and Weekend Weather 22-23 Oct

The radar picture on Friday.
The radar picture on Friday.

Certainly not as interesting as last weekend but it will still offer challenges to boaters this weekend. The big regatta’s are the Sloops Race Your House and then their Fall Regatta on Sunday. Big turn out and it will of course be lots of fun.

This will probably be another case of you should have been here yesterday as we will have near perfect conditions today and not so good for Saturday The Friday morning surface chart shows a nice low off of SE Alaska with another low forming ofåf of the mouth of the Columbia River. This afternoons radar shows a fairly strong band of rain showers moving over the coast and headed our way for this evening. Once this moves through a weak high pressure system will form over central Oregon and move north into southern BC during the day on Saturday. This will probably result in light and variable winds for the afternoon.

Sunday looks to be a better day as another front approaches the coast. As we saw last weekend the speed and strength of this front can vary a great deal as it approaches the coast. Keep your fingers crossed.

 

 

Tides at West Point for the weekend

Saturday

0712                        Flood                       .92 knots

1030                        Slack

1154                        Ebb                            .33 knots

1606                        Slack

1936                        Flood                       .43 knots

Sunday

0818                        Flood                       .88 knots

1136                        Slack

1254                        Ebb                            .29 knots

1636                        Slack

With the nice southerly we’ve had all day today and certainly plenty of rain this week in addition to the rain we’ll get tonight you can expect the slack water to occur earlier, the ebb to start sooner and run stronger. You’ll also see that band of muddy, freshwater from the Duwamish running around West Point which will be a great indicator of where you’ll find the strongest part of the ebb. It has been so muddy along the north side of Elliott Bay that is has messed up squid jigging at the fishing pier near the grain terminal. Then again I guess when you have seven inches of rain so far in the month of October compared to a normal of about 1.75 inches, it has to go somewhere.

I also included the 96 hour (Tuesday) surface forecast because it’s a very interesting chart with lots of activity headed our way this coming week.

Enjoy the weekend.

Ed. Notes: Sorry I didn’t get this up yesterday afternoon, but I was actually out racing in SYC’s Grand Prix Regatta. Great racing conditions and there are some very close classes, including ORC 1 where Smoke and Glory split races and in Class 3, where I was sailing, which has 3 boats tied at 5 pts after Friday. 

Also: Bruce reminds boaters and marine industry folk that next week is the NMTA Marina and Boatyard Conference  in Bremerton. “It’s not free but it will definitely be worth it,” he says, and I agree. I’ve been to several and there’s much to learn and many people to meet. -Kurt

Bruce’s Brief for Saturday, October 15 Storm

Bruce’s Brief for Saturday, October 15 Storm

Not much has changed since yesterday except that this storm will now hit the NW corner of Washington before going into Vancouver Island The baro is dropping rapidly and we are certainly having plenty of rain. The wind predictions from yesterday remain the same for today except for the San Juan Islands, Gulf Islands, Lower Strait of Georgia, Bellingham, Blaine, and Pt Roberts area which because the storm is moving further inland, could be hit a little harder. By that I mean 50-60 knots with gusts over 70. This will start around 1800 hours and last through 2200 hours.

Now I’ve got to go clean out my gutters and the street drain.

Stay safe

Saturday of PSSC Cancelled

Bruce’s Brief: WEATHER UPDATE: Friday afternoon to Sunday morning

Bruce’s Brief: WEATHER UPDATE: Friday afternoon to Sunday morning
1800 Saturday
1800 Saturday

As we suspected yesterday the trajectory for this storm has shifted to very slightly further offshore which will not diminish the impact to the coastal waters but will slightly reduce the impact to the interior of western Washington. Still, this is a dangerous storm and you shouldn’t back off on your preparations. Again, it will largely depend upon where you are as to the impact so I will try to break it down by area.

Overnight we had some impressive wind speeds around the Northwest. Diamond Pt/Discovery Bay 48 knots, Buoy Juliet Alpha at the entrance to Straits 40 knots, and Destruction Island 59 knots. Today we’ve already seen 35 at West Point and 53 at Cape Disappointment.

Take a look at the Surface charts and note how fast these storm systems are moving towards us and then compare the forecast picture from yesterday to today and note that the system has moved offshore, slightly. It currently is projected to come onshore at Barkley Sound on Vancouver Island, after 1800 hours tomorrow evening.

As you can see, this is as we said a prolonged wind and rain event. The problems with wind combined with a high tide will be that as boats rock up and down in the marinas, the fenders will ride up and on to the dock which will leave a nasty mark on any hull. In addition, there will be chafe on the mooring lines which will lead to breakage. As my dear old Dad said, “There is no substitute for a close visual inspection. You also have to see what you’re looking at.”

For boat owners and marina operators this will mean walking the docks to see what’s going on and working ahead of potential problems.

I’ll get another one of these out tomorrow morning.

Be safe out there.

 

 

 

 

 

Bruce’s Brief: Details for the Coming Storm

Bruce’s Brief: Details for the Coming Storm

No question, this will be a prolonged rain and wind event. The good news is that the projected track will keep it out of the interior of Western Washington and keep it off the coast. That doesn’t however diminish the potential effects that we may see in the Salish Sea. It will really depend on where you are so I’ll try to break it down as much as I can.

sat-pm
Storm as it is projected to look at 7pm Saturday.

The first event will begin to show up late tonight and into tomorrow morning with winds in the central Sound 25-30 knots ESE and the south coast of Washington 30-40 knots of ESE. By 0200 look for 30-40 knots of southerly from Alki, over Elliott Bay and into the north Sound. By 0300 The entire coast will experience 25-30 with gusts to 40, the same for the central Sound north to Bellingham Bay and this will last until late afternoon and into the early evening on Friday.

The second and stronger event will start early Saturday morning and will be marked by a rapidly dropping barometer. Be sure to set it because this will probably be the lowest we’ll see this year. The other indication that this will be a fairly strong system is the that you will see that the frontal wind, instead of being southeasterly will be a pronounced due easterly. When this occurs, if you’re on the water, it’s time to seek shelter ASAP. The good news is that with high tide at around 0400 and 1645 this will drive the water off the coast and reduce the amount of storm surge. We’ll see the breeze start to build by late morning and remain out of the east and east-southeasterly direction.

By noon on Saturday the south coast of Washington will see ESE 45+ knots, the Straits from Race Rocks to the west 30-40 knots of easterly and the Central Sound 20-30 knots from the east-southeast. By mid afternoon from Newport, OR to Westport you will see a steady 50 knots with gusts to 60 of SSE, slightly less north of Westport. In the Straits from Race Rocks to Neah Bay there will be 35-45 knots of easterly with higher gusts. In the central Sound 15-25 knots of ESE.

Into the late afternoon and early evening the Coast will see 35-45 knots, the entire Straits will have 30-40 from the ESE. The central Sound 30-35 from ESE. By sometime between 1800 and 2000 hrs the front will have pased which will bring the wind around to the west-southwest on coast and from the Columbia River to Westport expect 45-50 knots with higher gust. From Westport to Neah bay 35-45 with higher gusts. In the Salish Sea From Anderson Island to Port Townsend SSE 35-45 knots. By mid evening from Olympia to the Strait of Georgia look for 35-45 from the south, in the Straits from Pt. Townsend to RR ESE 35-40.

Around midnight on Saturday the post frontal effect of west-southwesterly breeze will in place over the entire area. In the Straits from Race Rocks to Whidbey Island 45-50 knots of WSW, NB to RR WSW 30-40. In the Salish Sea from Olympia to Pt Townsend SSW 25-35.

Early Sunday morning it will start to ease to SW 20-30 along the coast, 25-30 from Olympia to Anacortes and from Anacortes north to the Strait of Georgia 25-40 of SSW.

There’s still time to check the boat and add those extra mooring lines and fenders.

I’m headed down to Elliott Bay Marina and Shilshole this afternoon to scope things out and I’ll have another update for you tomorrow around noon. A huge thank you to Kurt Hoehne for his help on all of this.

Early Warning – Big Wind and Rain Coming to the Salish Sea

Early Warning – Big Wind and Rain Coming to the Salish Sea
friday-14-octsurface-forecast
96-hour forecast issued yesterday.

If you liked wet and wild you’ll love what’s coming. Remember a couple of weeks ago I pointed out what could happen with the jet stream and post tropical depressions? Check out post tropical Songda headed right at us this weekend. WOW!

WEATHER ALERT! This is NOT a drill.

Don’t say we didn’t try to warn you. Starting tonight along the coast you can expect high winds and plenty of rain. This however is just the start of what will be a prolonged high wind and rain event lasting through Sunday. Starting on Thursday evening the South coast of Washington and the San Juan Islands can expect 30+ knots of southeasterly breeze, with Bellingham Bay, Pt Townsend, and Admiralty Inlet seeing 40+ knots.

By Friday morning this will extend to the central Sound from Tacoma to Everett seeing 25-30 knots. Remember also that this a time of unusually high tides which combined with high winds can wreak havoc in marina’s. On the coast the highs will be at noon and midnight. In Seattle on Thursday the high will be at 1537, Friday morning 0400 10’, Friday afternoon 1611 11.6’, Sat morning 0445 10.7 feet, Sat afternoon 1645 11.9’ .

Saturday morning on the coast will see the arrival of the next front, with high winds coming up again in the San Juan Islands. By midmorning the winds will be building in the central Sound, and Admiralty Inlet. Just before noon the south coast will be seeing 50+ knots of southerly , with winds over the central Sound, Admiralty Inlet and San Juan’s rising to 30+ from the south. This will continue through evening with the strongest winds, 60+ knots, being over the north coast, Westport to Neah Bay. Expect winds of 30-45 knots from Olympia to the Straits of Georgia with potentially higher winds in Admiralty Inlet and Port Townsend.

As I said, this is a prolonged high wind and rain event with the potential to knockout power, take down trees, cause lowland flooding, generally make a mess of things. If you haven’t already, it’s time to add extra mooring lines and fenders. If you’ve left your roller furling sails up, it’s time to get those down and into your sailmaker for their annual inspection and maintenance.

Be safe.

Ed. Note: I believe Bruce, and took the genny off Slipstream already. Here are the warnings from a couple of other guys who know a lot about weather in the Northwest:

David Burch’s thoughts here.

Cliff Mass’s Take on the upcoming event is here. 

Last Saturday’s PSSC Blast

You could see in the Friday morning surface chart that a new low was forming and in the Saturday morning chart it was going to rapidly move over the area. By Friday night the gradient was deepening way more than expected and by Saturday morning the NWS had issued small craft warnings for the Sound and Admiralty Inlet.

If you checked the gradient over the Northwest the Portland to Bellingham difference was 3.2 millibars  which tells you to expect 30 knots over the central Sound. In the eastern straits, Protection Island, Dungeness Spit it was northeasterly at less than 5 knots. Ah yes, micro-weather in the Pacific Northwest.
