Coho Ho Ho Rally 2014 - Brads Weather brief August 24 Sunday

Brad Baker's Coho ho ho weather report combined 0900 pdt August 24, 2014

 

Good morning Fleet.  I have to keep it short this morning as I failed to get up early enough and the family has plans for today.  I can tell you its beautiful weather this morning here in Seattle.  In other news a magnitude 6.0 earthquake struck N. California this morning near Sonoma.  It was a shallow quake, therefore fairly violent.  Reports are still coming in of course, but it looks like no deaths, though the wine industry may have taken a bit of hit.

 

The weather forecast has remained consistent.   The high pressure offshore is forecast to weaken while the thermal low move a bit west starting late Monday.  The Northerly winds will remain strong today and Monday from just North of Blanco extending down to near Mendocino.  There will be a shift late Monday as the winds will get lighter South of Blanco and the strongest wind field shifts a bit North before it too moderates come Thursday.  The wind and seas will be worst around Cape Blanco initially and then Cape Blanco and extending North Tuesday into Wednesday.   Wind off the Washington coast will be mellow during the 4 day forecast period blowing 0 -15.

 

Forecast:

 

WA coast – Light winds to 15 from the N.  Seas 3-5 feet from the W to NW.  wind waves 2' or less.  This forecast holds Today through Thursday.

 

Oregon and Northern California Coast

 

Today

 

Columbia River to Newport – N wind 5-15 gusts to 20, Seas, combined wind waves and swell to 6' at 7 seconds from the NW.

 

Newport to Cape Mendocino – N wind 10 – 30 with higher gusts possible.  Seas, combined seas from the N at 11' at 8 seconds mixed with a 2-4' swell from the S at 15 seconds.  Remember that when wave height is forecast this is an average number.  There are always larger waves at times.  And you may have noticed that they come in sets.

 

Cape Mendocino to SF – N to NW wind 5 – 25 with gusts to 30.  More wind in the North portion and more than 10 miles offshore.  Remember there is always the possibility for fog pretty much anywhere on the coast.  Seas 6-8' from the N with a shorter period combined with 4' swell from the S with a long period.

 

Monday August 25

 

Columbia River to Newport – N wind 10 – 25 with higher gusts possible.  Strong winds will be closer to Newport.    Seas Combined seas to 7 ' at 7 seconds from the NW.

 

Newport to Mendocino – N wind 10 – 30 with gusts to 35 possible.  Seas, combine seas from the N to 10' at 8 seconds mixed with 2-4' swell from the S at 15 seconds.

Entire Oregon Coast – N winds 10-25.  Strongest winds at Cape Blanco and starting to extend North.  Seas, Combined waves from the N 5-7'.   South and SW Swell to 2' at 15 seconds.

 

Northern California – N winds 0 -15.  It is possible there will be variable directions but should be light.  Seas Left over slop from the North 7' at 8 seconds.  South to SW swell 4' at 15 seconds.

 

Wednesday August 27

 

Oregon Coast – N wind 5-20 with strongest winds Cape Blanco to Newport.  Winds will subside during the day.  Seas, wind waves from the N. to 5', S to SW swell 2' at 15 seconds.

 

Northern CA – Mostly N winds forecast not to exceed 15 knots.  I imagine there will be a whole lot of nothing at times.  The N wind waves should be about 5' with an impressive 5' Swell at 16 seconds forecast.

 

Thursday August 28

 

For entire Oregon and N. CA coast winds are forecast to not exceed 15 knots, mostly from the N., but I expect variability, especially south of Mendocino where there could be light W and SW winds.  Seas should be mellowed out by now with the exception of the pesky south Swell which should still be running at 3-5' in the N. CA waters.
