Bruce’s Briefs: Wx for 14, 15, 16, 17, and 18 July

Welcome to summer in the Pacific NW. We are going to have a slightly warm Saturday and a cooler Sunday, with still no rain in sight.  Again, compared to the rest of the country, we are so lucky. If you look at the big picture we have the fifth named storm in the Atlantic (Don) and the third named hurricane (Calvin) in the Pacific. As Calvin weakens on its path to the West it does have the potential to impact the Big Island of Hawaii with rain and some wind just not of hurricane force. For this early in the season, that’s a bunch of named storms, and conditions in both oceans favor more storm development.

If today’s Brief sounds familiar, it should because our situation hasn’t changed very much. Today’s sat pic does show an interesting new development with smoke from the BC wildfires just north of Idaho and starting to flow into Montana, this will increase over the next couple of days however it will not impact the Salish Sea, yet.  

We still have a very weak and unstable high-pressure system off the California coast with a ridge of high-pressure building along our coast. We also have a very weak low-pressure system (1010MB) with an attached cold front due west of us however this will degrade as it hits the ridge and the coastal buffer zone. By Sunday the low will have drifted to the north and the cold front will have drifted slowly towards the coast.

For the local area, boaters can expect light wind in most of the waters until the onshore breeze fills down the Strait of JdF. This will result in small craft advisories and potentially gale warnings for the Central and Eastern Straits for both Saturday and Sunday. Exercise caution if transiting those areas.

Enjoy the weekend and as if the Chamber of Commerce weather we had for the All-Star Game wasn’t bad enough, don’t tell your friends in the rest of the country what we have going for us out here now! 

Bruce’s Briefs: Wx for 7, 8, 9, and 10 July. Plenty of summer wx ahead, not too hot but still very dry and getting drier.

Bruce’s Briefs: Wx for 7, 8, 9, and 10 July. Plenty of summer wx ahead, not too hot but still very dry and getting drier.

We did see our first intrusion of wildfire smoke into the area this week however with our somewhat stable and repetitive weather pattern, it didn’t last long. The problem with our dry weather is the potential for wildfires as witnessed by communities near Shelton and the Columbia Gorge. Take a look at the map of the Potential for Wildland Fires in July. About 60% of the State of Washington is above normal while the rest of the State is at normal. Scary!  As we said last week, all it can take is a slight change in this pattern to bring more smoke into our area.

Today’s sat pic is very interesting showing that persistent marine layer along the coast as far south as Mendocino. Also visible is a weak cold front off the coast and a very weak low-pressure system off of mid-Vancouver Island. All of which will help keep the onshore flow coming down the Straits keeping our temps cool and the air clean. It will also bring the summertime strong westerly breezes to the Central and Eastern Straits usually in the late afternoon and early evening. Plan accordingly.

For Saturday in the Central Sound, we can expect a somewhat unusual south-to-southwest breeze of 5-12 knots until the onshore breeze fills down the Sound at 10-15 knots around mid-afternoon.  Sunday in the Central and South Sound conditions will be light until mid-afternoon when the onshore flow finally fills down the Sound around mid-afternoon.

All in all, another beautiful weekend for the Salish Sea.  Use sunblock and always be careful with fire any place you go ashore. 

Bruce’s Briefs: Wx for 30 June, 1, 2, 3, and 4th of July. Spectacular Weather Ahead!

Bruce’s Briefs: Wx for 30 June, 1, 2, 3, and 4th of July. Spectacular Weather Ahead!

So much for the old saying that summer in Seattle doesn’t start until the 5th of July. We are in for some great weather for the foreseeable future. Plus with the diurnal breeze filling down the Straits in the afternoon, evening sailing will be great in the central Sound. Witness the last two Downtown Sailing Series races in Elliott Bay. No wind until about 1600 hrs then a nice N-NE breeze fills in and builds to 12-15 knots. Everyone gets around the course in about 1-1.5 hours so plenty of time to enjoy the great post-race party. Then by sunset, the breeze drops so the trip back to Shilshole is pleasant and not too cold.

This is the good news. The bad news is that with all this great weather there is no rain in sight and the fire danger will definitely be increasing. All the more reason to spend more time on the water.  Then there’s the weather in the rest of the country, we are so lucky. At least at this point. With the fire season well underway in Canada, we are just a slight shift in this pattern away from smoke coming our way. Keep your fingers crossed. 

The other interesting part of this is that TransPac is just getting started and as usual with the staggered start sometimes you eat the bear and sometimes the bear eats you. The smaller boats and the cruising boats are well underway and enjoying some high-speed close reaching. The big boats start tomorrow and it will be lighter for them so no records this year. The other interesting fact is that there are no real rocketships entered this year.and only ONE TP-52 is making the run to the Islands. You have to wonder why?

Today’s surface chart shows a weak L-shaped Pacific High (1026MB) with quite a gap in the isobars surrounding the high. The other interesting feature on today’s charts are the not one but two hurricanes off of Mexico, Adrian and Beatriz. Adrain will weaken and become a post-tropical cyclone not presenting any threat to the TransPac fleet. Beatriz will weaken as it moves up the Mexican coast from Z-town to Cabo and it will do damage to those coastal communities with winds near 80 knots and heavy rainfall.

As we approach the 4th, the Pacific High will only build to about 1030MB and still not assume a round, more stable shape. It will remain weak and out of position for at least another 10 days. This will allow the TP fleet to sail a shorter course and should make the delivery back to the coast a little easier.

For the Pacific NW the strongest winds, 15-30 knots, will be tonight in the Central and Eastern part of the Strait of JdF.  The rest of the weekend will see some residual breeze come down the Sound as well as swing up into the SJ Islands. The breeze will tend to light in the mornings and then gradually build in the afternoon. Also, while the air temps will be on the warm side, the water temps are still cold, and hypothermia is still a real possibility. By Tuesday and Wednesday, a thermally induced surface trough of low pressure will move up from California and Oregon. This will weaken the onshore flow and reduce the diurnal breeze over the area.

Enjoy the weekend, stay safe, and use the sunblock!

Ideal summer is finally in the Pacific NW. Congratulations to Jeanne and Evgeniy Goussev and the team on Gray Wolf for winning the 2023 R2AK, tough race and they trounced the competition! An outstanding example of planning, execution, and seamanship.

Once again, we are so lucky to be living in the Pacific NW. We just have to balance the weather with the very high cost of living, increasing gun violence, and failing infrastructure. Most of the country has the same problems but with terrible and dangerous weather. Our great weather will hold well into next week while the rest of the country will continue to suffer. Did I mention Hurricane season? It won’t affect us however the waters where these form are extremely warm and will continue to warm as the summer goes on even though the days are getting shorter.

Today’s pattern is very similar to what we’ve had recently with weak high-pressure offshore and a weak trough of low-pressure inland. This will keep the onshore flow we’ve had in place for at least the next week. 

The surface analysis chart, today’s 500Mb, and the sat pic show just how lucky we are to be where we are on the Salish Sea. The sat pic shows the coast to be well enveloped by a persistent maritime layer (June Gloom)  that only briefly clears in the late afternoon. The sat pic and 500MB chart also show a weak upper-level low-pressure system (565MB) right on top of us. With the jet steam well to the north of us, we will be protected from any storm systems coming along as well helping to keep our temps very pleasant.

Plenty of sailing and racing to be done this weekend however conditions will remain light for the central and south Sound while the Strait of JdF will have the usual breeze with small craft advisories and gale warnings at times. There will be some onshore flow that will make it down the Sound late on Saturday and Sunday.

Enjoy the weekend, use the sunblock, and stay safe.

Bruce’s Briefs: Wx for 9, 10, 11, and 12 June. The June gloom descends upon us!

Saturday will be pretty much a repeat of today with cloudy, overcast conditions, plenty of wind in the Straits (34 knots of westerly at Race Rocks now), and light and variable conditions in the Sound.

The current surface analysis chart, sat pic, and upper-level charts all confirm that not much is going to change for tomorrow. We still have a weak high-pressure system offshore and a weak trough of low-pressure inland with another trough of low-pressure offshore.  As that trough dissipates offshore and slides to the SE, Cape Mendocino will see gale force conditions and steep seas, a typical summer pattern. The isobars over the Salish Sea will be quite far apart so very little pressure gradient.

By Sunday an approaching front coming out of the Gulf of Alaska will tighten the gradient in the Sound bringing light air to the Straits, partly cloudy conditions to the Sound with a nice 10-14 knot northerly. Clearly the nicest day of the weekend.

Expect more clouds for next weekend.

Bruce’s Briefs: Wx for 2, 3, 4, 5, and 6 June. Lots going on with the Seventy48 starting tonight, Saratoga Sprint, Blake Island, Classic Mariners Regatta, Van Isle 360, and on Monday the R2AK. 

After last weekend (Swiftsure) I’m sure we were looking for a bit of a break. It did take a little longer to recover from that beat in 20-30 knots and some boats just decided to drop out because they were leaving for the Van Isle 360 and didn’t want to risk any damage. The most amazing story and the award for exemplary seamanship has to go to the Riptide 35 Terramoto, skippered by Bill Weinstein and sailed by some of the best sailors in the Pacific NW. They dismasted about five miles from the finish, assessed the situation, and simply decided to tidy things up and sail the rest of the way to the finish. The dismasting barely slowed them down as they were first to finish on the Cape Flattery Race and corrected out to first in class and first overall by 44 minutes over the second-place boat. Outstanding!

Our pattern for the last week will finally ease the breeze in the Straits for the start of R2AK. Before that, we will continue to have an onshore flow which will bring afternoon gales to the Strait of JdF. Today’s surface analysis and sat pic continue to show a ridge of high pressure over the coastal and offshore waters with a weak trough of low pressure over eastern Washington. Same story as last week. The interesting part is in the 500MB Charts which show a weak upper-level low in the eastern Gulf of Alaska which is keeping the jet stream coming ashore mid-Vancouver Island. It will also bring the remains of a cold front ashore Saturday afternoon. This will not adversely affect our weather however it will bring a slight increase in the onshore flow down the Straits. Not great news for the Van Isle, Saratoga Sprint, and Blake Island Racers.

The wind will be light in the morning with some breeze filling down the Sound around midday and then building into the evening. For the start of Van Isle, it is just going to be light with some breeze filling down the Strait of Georgia by mid-afternoon, and then going light again by early evening.

For the Seventy48 folks starting tonight, there may be 10-15 knots of northerly however that will ease to 10 knots or less by 2100 hrs and stay that way until midday Saturday.

The group that will benefit the most from a slight change in the weather will be the R2AK folks who will start in about 10 knots of westerly only to have the breeze become light and variable about ½ way to Victoria. By mid-afternoon, a westerly will fill down the Straits and then slowly build into the evening.

Overall, it will be a great weekend to be on the water, just use the sunblock and stay safe. Have a great one!

Bruce’s Briefs: Wx for 26, 27, 28, and 29 May. Swiftsure Race!

Bruce’s Briefs: Wx for 26, 27, 28, and 29 May. Swiftsure Race!

If you’ve been watching the models this week, it has been a very interesting roller coaster ride with conditions going from extensive areas of calm to gale-force winds. Right now it looks like it could be a very nice race with wind around the course and enough breeze to make it exhilarating for the run through the Race to the finish. Particularly if you’re going through around the time of max ebb early on Sunday morning when we could have 20-30 knots of westerly. It will be like sailing in the Waring Blender.

Today’s surface analysis chart shows a weak trough of low-pressure running up the interiors of California, Oregon, and Washington with a building high-pressure system (1031MB) offshore. This will keep the pattern we have seen in the Straits for the last couple of days holding over the weekend and into next week. That pattern is one of light breeze in the morning but building in the Straits in the afternoon and into the overnight hours. 

What we do know is what the tidal current will be in Race Passage for this weekend.

The surface forecast chart for tomorrow, while it shows an increase in the gap of the isobars over the Salish Sea, we are still going to have a nice breeze for the start and breeze all the way out the Straits. Right now it looks like 8-15 knots of WSW breeze for the start and holding until about 1100 hours when the breeze will build into the 15-22 knot range and clock to the NW. By mid-afternoon, the breeze will build into the 20-26 knot range and stay out of the NW. This will hold out to the Swiftsure Bank while it will continue to follow a traditional pattern of building from Sheringham to Hein Bank. Remember, the breeze can double from Sheringham to Race Rocks so you should prepare in advance and talk through the steps in advance of getting the spinnaker down in breezy conditions. By 1600 hours we could have 25-32 knots of NW from Sooke to Hein Bank and this will hold in this area until 0400-0700 hrs Sunday morning when it will ease to 15-20 knots.

The breeze in the Straits from Sheringham to Swiftsure Bank will hold in the 12-22 knot range until around 2200hrs when it will slowly ease to the 10-15 knot range.

By 0100 hrs breeze will be down to 8-10 knots. By 0400 hrs the breeze from Cape Flattery out to Swiftsure Bank will become light and variable and stay that way until about 1300 hrs when the westerly will fill down the Straits again.

As mentioned above, the breeze can build dramatically from Sheringham to Race Rocks, and if you’re running you better start preparing to change down and maybe just sailing through the Race with the number 3 and no spinnaker. Then resetting the kite once the wind eases and the seas flatten out.

So sunblock on first thing, foul weather gear, life jacket and harness on before you leave the dock.

Be safe, have fun and have a great race.

Bruce’s Briefs: Wx for 19, 20, 21, and 22 May. A cloudy but pleasant weekend ahead for the Sound, breezy in the Strait of Juan de Fuca.

After a warm week, the onshore flow has returned and that has brought Mother Natures’ air conditioning back to the Pacific NW. It has also sent the smoke and haze from the wildfires in BC and Alberta to Eastern Washington. Take a look at the sat pic for yesterday.

The surface analysis chart shows that we still have a weak ridge of high pressure along the coast with a weak (1014MB) low-pressure system over Eastern Washington. This will keep the onshore flow in place well into next week. Also still in place over the Gulf of Alaska is that large but weaker low-pressure system with its attached cold front. There is a possibility the tail of the cold front may drag over the area on Tuesday. The 500MB charts show that this large low protrudes into the upper atmosphere and the jet stream is such that it won’t be moving very much.

The other interesting feature in the 500MB charts is the 96 hr chart which shows an upper level, cutoff, low-pressure system forming right over the Pacific Northwest, while the jet stream travels around this low and goes into southern mainland Alaska. This could make for a very interesting Swiftsure.

Winds for the weekend will stay a little on the light side for Puget Sound and Admiralty Inlet with some breeze filling down the Sound by mid to late afternoon. Wind in the Strait of JdF until mid to late afternoon will also be light however as the onshore breeze develops, it will blow in the Strait at 25-30 knots by early evening and hold until just after midnight. Sunday will see a similar pattern.

It is still a week until Swiftsure so anything could happen however, right now two models are showing that this could be a very long and very light Driftsure. So we’ll see.

Have a great weekend!

Bruce’s Briefs: Wx for 12, 13, 14, 15, and 16 May. Vashon Island Race

Bruce’s Briefs: Wx for 12, 13, 14, 15, and 16 May. Vashon Island Race

It’s going to be a perfect weekend to be on the water and especially to race around Vashon Island.  A downwind start, a nice run all the way to the bottom of Vashon, the usual light spot at that point, a nice beat with the current up Colvos, at Blake Island go across the Sound when you can lay Four-mile Rock, don’t go aground south of West Point, and then after West Point tack when you can lay the finish. Easy. Plus, it will be warm. Put the sunblock on BEFORE you leave the house and then re-apply before the beat up Colvos.

Yesterday the Pacific NW Offshore Race got underway off the mouth of the Columbia River in pretty much ideal conditions and today are in a bit of light air just south of Cape Flattery. That will change this afternoon when more of a NW breeze fills down the coast. The first boats should be in Victoria early Saturday morning.

What we have today and leading into what will be the warmest days we’ve seen this year is a weak ridge of high pressure that is building along the coast. As you can see from today’s Sat Pic we also have a thermally induced surface trough of low-pressure moving up from California. With high-pressure over eastern Washington, this will bring an offshore breeze over the area and a nice northerly to Puget Sound and it will last well into the evening.

The other charts of interest will be the upper-level or 500MB charts. The jet stream is now solidly into meridional flow and now comes ashore in SE Alaska. This will have the dual effect of bringing the warmer air up from southern California as well as keeping that big low-pressure system with its attached frontal systems trapped in the Gulf of Alaska and away from the Pacific NW. Let’s just hope the snowpack doesn’t melt away too quickly. Also, look at the 96hr 500MB chart. The jet stream will then flow straight into Seward. This has caused an upper-level, cut-off low-pressure system to form about halfway between Hawaii and the Pacific NW. The TransPac sailors are praying this doesn’t happen during their race.

The Vashon Race can expect 8-12 knots of northerly for the start and note that it’s northerly not NW. Yesterday and today in the 0900-1000 time slot there was more wind on the east side of the Sound with the west side pretty dead. There is also a NE component to the breeze on the south side of  West Point, Alki, and Three Tree Point which is also the shortest course to Pt. Robinson. Also, remember that if you’re using SailFlow, the anemometer at the Alki Lighthouse is broken and just stays stuck at 9-10 knots from the North, even when it’s blowing from the south.

At the south end of Vashon don’t get caught too close to the Island where the current can be on your nose and the wind very light. For the beat up Colvos you’ll probably have 10-14 knots of northerly and it will follow the bends as you beat north. There won’t be much tidal current so it will be easy to find the long, favored tacks as you work your way north.

Once you exit Colvos stay on the east side of Blake Island and beat your way up to Restoration Pt. At Restoration, it will be time to take the long port tack across the Sound to Magnolia aiming roughly at Four Mile Rock. Just remember it is plenty shallow from along the bluff from Four Mile to West Pt. After you clear West Pt, hold starboard until you can tack and lay the entrance to the Ship Canal, Then plan your approach to the finish line.

Have a great race, enjoy the day, and resist the temptation to jump into the water after you finish.

It’s not going to be the nicest weekend but it also won’t be freezing cold. We’ll get most of the rain over by tonight however there will still be a few passing showers around tomorrow. In other words, just another spring-like day in the Pacific NW. The one thing you won’t have to worry about this weekend is too much wind. Tidal currents will be an issue because of the light air. At least for Saturday, you’ll have the big ebb of the day to push you north. Just be ready to take your time at Foul Weather Bluff(FWB), because when the flood starts, the wind will ease, making getting around Marrowstone a challenge.

The sat pic for today and the surface analysis chart show the weak front that’s going over us today as well as the centers of the two low-pressure systems off of the coast. One is off of the Strait of JdF and one off of the Calf-Oregon border. Both are weak systems however with the jet stream remaining well to the south, these systems won’t be moving very fast or very far.

The surface forecast charts for the weekend continue to show a very weak pressure gradient over the Salish Sea. With light conditions for Saturday and 15-20 knots of SSW for Sunday. Saturday will start off with light and variable breeze until about noonish when a light northerly will fill down with the start of the flood tide, the Swihart Effect. You may have 10-12 knts of northerly from Pt No Pt to FWB just not much beyond FWB. There will also be plenty of breeze in the Straits, it just won’t get as far as Pt. Townsend.

Sunday will benefit the big boats and later starters as they will have more breeze and it will be a beat. The early starters will be in less wind and the start of the ebb. By 0900-1000hrs you could have 15-20 knots of SSW breeze. This however will only last until about 1200 hrs when it will start to ease and by 1500 hrs the breeze will be 4-8 knots of SSW from Jeff Head to the finish.

All in all, as it always is, it will be a great, fun weekend. Just be safe, and good luck!

Pacific NW Offshore Race starts May 11th and while it may look like these low-pressure systems may pose a threat, they will remain offshore and provide racers with challenging and frustrating conditions. Maybe a little bit of running for the start off of the Columbia River becoming a close reach and then a beat the rest of the way to Victoria. First finishers in on Saturday afternoon. Luckily this could all change by Thursday, keep your fingers crossed. We will have an update on Monday and then a more detailed forecast for the Skippers meeting on Wednesday.
