Brads Weather Message for August 25th

 

My apologies for missing yesterday!

 

I see that Nutmeg is now South of Newport Oregon by 10 or 20 miles.  Also it appears that Manatee is on the move heading back North perhaps.   The one remaining boat yet to leave is Athanor which has plans to cut lines I believe on the 31^st.  Given boat positions, this forecast will be for the waters from Newport Oregon to SF.

 

The Large scale pattern has now shifted, and the dominant feature is an upper level low currently well off the Washington Coast.  This low is currently far enough off the coast that a week ridge of high pressure remains  between it and the coast itself.   Light Northerlies still prevail from Flattery to San Francisco.  This will change eventually to Southerly winds. The big question is when, and where?  The US and European models don't completely agree on the timing, with the European model being more progressive with a quicker and wetter transition than the US GFS model.   The eventual outcome will be the low will slowly drift towards the coast with a transition to S to SW winds along the coast, starting in the Washington and Northern Oregon waters first and then the southerly winds will progress down the coast likely near or all the way to San Francisco perhaps by Friday.
