Subject: Weather for August 16

Just a few tweaks to the overall weather forecast for today.  The overall pattern is pretty much the same with the low pressure trough off the Coast dissipating as High pressure builds from off shore.  the biggest difference is the models show the trough lingering a bit longer in the Northern part of the forecast area from mid Oregon on up.  The net result is the Northerly winds North of Cape Blanco will be a bit slower to fill in and participants in this area will likely experience light southerlies or no wind at all.   Unfortunately (or fortunately depending on your disposition) the strong NW winds and associated building seas from Cape Blanco South are still very much in the forecast.

Strait of Juan de Fuca

Variable winds to 10 knots today, possibly changing to west winds to 15 knots tonight.   For Saturday through Tuesday it looks like you can expect a diurnal cycle of lighter winds in the early morning building to as high as 20 knots (likely lower though) in the late afternoon and evening hours.

Washington and Oregon Coast North of Cape Blanco

I wouldn’t be surprised if you have a whole lot of nothing today and tomorrow, but the gradients do show the possibility of Southerly winds to 10 knots.  The exception being the Southern portion of this area where the N winds will likely start to build later Saturday as you get nearer to Cape Blanco.  For Sunday, Monday and Tuesday it will depend on where you are.  If you are further South the North winds will fill sooner.  If you are off the Washington Coast you may not see the transition until Monday.  Keep in mind this is a FORECAST only.  Sometimes (some may say often) the weather does not do what the models and the really smart meteorologists predict.  It is possible that the transition will happen sooner.  When the change over does happen there is likely to be a relatively sharp increase in the NW winds to perhaps 15 or 20 knots until it settles in.  The predicted average wind speed for the Northerlies ranges from 5 to 20 knots over this area.  Sea state forecast is a West swell 3-5 feet at 8 to 10 seconds.  Wind waves ranging from 0-3 feet depending on the wind conditions.

Southern Oregon and Northern Californian Coast Cape Blanco South

Light winds today transitioning to the North late and starting to fill.  On Saturday the transition should be in full force as the High fills and the inland low increases as well.  Expect N to NW winds to 25 knots by Saturday evening with Higher gusts.  The gradient should put the higher winds further offshore and lighter nearer the coast.  If you are within 10 miles you can expect 5 to 10 knots less.  For Sunday through Tuesday N to NW winds 20-35knots with higher gusts.  Within 10 miles of shore (except the capes which offer no protection) wind speeds should be about 10 knots less blowing in a range from 15 to 25.  This time of year these Northerly winds become more diurnal as the inland low fluctuates with heating and cooling as the days get shorter.  Strongest winds will be afternoon and evening with the lightest conditions occurring after midnight into the morning hours or at least that’s what supposed to happen.  Sea state forecast is West swell to 4 feet at 11 seconds today .  NW waves to 7 feet at 8 seconds on Saturday.  NW waves 11-12 feet at only 8 to 9 seconds Sunday through Tuesday.

For those who are inclined to wait out the strong winds and seas in the Southern Oregon N. California, perhaps in Coos Bay, the long range models do show the Pattern easing a bit starting Late Wednesday of next week.   Beware though that a forecast this far out is always suspect and subject to change.
