Weather Brief and Boat locations August 19, Monday

Karl report:
Locations as I know them August 19 - since most of the boats are holed up in port waiting for a weather window before proceeding, i've had fewer location updates.  I'll update on the blogsite as i get more responses today:  http://cohohoho.blogspot.com
sv Journey - in Eureka waiting weather window
sv Non Sequitur - reported in Coos bay yesterday
sv Dawn Treader - in Newport yesterday - heading for Coos Bay
sv Unleashed -  in Eureka waiting weather window
sv Moments - called in 11:45 today - Still in Westport, waiting weather, maybe leaving wednesday.  Adam said some other cruising boats were heading out this morning, hoping to go far out and get around the low.
sv Ohana - in Newport waiting weather window
sv French Leave - Tacoma (they have retired for now, and will no longer be listed by request)

I will email Brad and ask for a updated weather brief for Newport to San Francisco, specifically when to look for a break in the weather that might offer a good passage. but, see the note below

Subject: August 19 weather


High pressure is the dominant weather feature all along the coast with variation on North winds for the entire forecast area, excluding the Strait of Juan de Fuca which will have diurnal winds potentially to small craft warning strength in the central strait late afternoon and evenings.    The weather pattern with stronger pressure gradients between Cape Blanco and Mendocino is in place.  I did a quick check of buoy reports and winds are blowing a steady 20 knots about 15 miles off the coast.   Not too bad, but the speeds will likely pick up today and tomorrow and the relax as the high pressure retrogrades further offshore with an upper level trough predicted to replace the high pressure off the Oregon and Washington coast starting Thursday.

Strait of Juan de Fuca

National weather service is predicting small craft Westerly winds in the evenings Today – Thursday in the late afternoons and evenings to 25 knots.  My gut feeling is the winds will be less, but be prepared

Coastal waters all the way to Cape Blanco (this is a little different area then in the past)

Today – Thursday N to NW winds should prevail from 10 – 25 knots, expect some diurnal pattern with stronger winds afternoon and evening.  Winds will be strongest in the Southern half of this forecast area.   Sea state, West to NW swell up to 7 feet with wind waves to 4 feet

Cape Blanco to Cape Mendocino

Gales Today into Wednesday.  Winds speeds blowing up to 35 knots with gusts to 40.   Waves predicted to max out at 14' with a 9 second period.
Winds should be about 10 knots slower within 10 miles of the coast between the capes.   
Winds should lesson Starting on Wednesday on through the rest of the week, to below 20 knots by Thursday.

Cape Mendocino to SF

Today – Tuesday NW winds to 30 knots in the northern half of the forecast area, with lighter winds to 25 knots in the southern portion.  Within 10 miles of shore the winds should be substantially less, especially once you are well away from the cape.
Wed – Thursday NW winds to 20 in the North half, light winds to SE winds to 10 knots in the South half
Seastate, NW swell to 8 feet at 10 seconds
