Bruce’s Briefs: Wx for 10,11, 12, 13, and 14 Nov. It will be blustery, at least on Saturday for one of our favorite races: Round the County!

From the past, we have learned to expect almost anything on Round the County and this year will be no different. We have a fast-moving front going through tonight with a post-frontal situation setting up for tomorrow which will bring a strong onshore flow down the Strait of JdF. This will carry up into the race course with the possibility of some fast sailing tomorrow with the only on-the-wind work being a hard beat from Patos to Turn Pt. Sunday will be much different.

Tides can be a factor however this year they are minimal.

Today’s surface analysis chart shows an impressive low-pressure system (973MB) in the Gulf of Alaska with an attached frontal system. The warm front is moving through now with the cold front to follow early tomorrow morning with plenty of rain and wind. The 24-hour Surface Chart also shows the next fast-moving front coming towards us.   Notice today’s 500MB Chart which is very zonal, flowing straight across the Pacific and coming ashore in Central Oregon. This will allow more storms and cooler temps into the Salish Sea this coming week.

For tomorrow the highest winds will be just after midnight and then ease slightly as we get closer to starting. The flow over the race course will be consistently SW with some local variations. As always, the smart thing to do will be to have the jack lines rigged and everyone in PFD’s and safety harnesses before the start. The reason being that while conditions in the starting area will be mild (10-15 knts) after Lawrence Pt the wind will build to SW 20-30 knts. Think about changing to a smaller kite and getting everybody stacked on the aft rail. Remember, always depower the boat from the back to the bow. Main, vang, then kite. Also, having whatever headsail you’re going to use from Patos to the finish,  up under the kite will help you keep the bow down and get the boat back on its feet faster after a crash.  

0900     SW       20-30 knts        Lawrence to Patos

1000     SW       20-25 knts        Lawrence to Patos, Patos to Turn Pt (TP).

1100     SW       15-25 knts        Patos to Turn Pt, Turn Pt to Finish

1200     Same

1300     Same except that the wind will shift to the WSW the closer you get to Stuart Island. Water will tend to flatter closer to the Island and you’ll be out of the flood tide.

1400     SW       15-30 knts        Patos to TP and TP to the Finish.

1500     SW       20-35 knts        Patos to TP and TP to the Finish.

1600     WSW    20-30 knts        same

1700     WSW    15-25 knts        same

1800     WSW    15-20 knts        same

Sunday will be quite different as the first day after frontal passage (Saturday) always brings the strongest breeze. The onshore flow will weaken and we will start to see the effects of another frontal system on Sunday morning. This will bring SE breeze to the area however as this front stalls off the coast, the SE will ease and become more of a drainage easterly-northeasterly coming down out of the Fraser River Valley. It will be this transition that will be the challenge on Sunday. By late Sunday afternoon, a stronger pre-frontal SE breeze will build over the area.

Sunday

0800     SE-ESE  15-25 knts        Start to Davidson Rk
