6PM Alternative Bay forecast for Saturday by Mike Godsey

[windfind]

The Weatherflow server is down so I can not post the forecast in the normal manner or use many of our forecast tools. So the forecast below will have to suffice until 7AM

Slightly weaker version of Thursday's up and down winds. The North Pacific High's surface NW winds are on the verge of departing from the coast but they should hang around through Friday afternoon. In addition strong NW winds will just aloft which will transfer some momentum to the surface winds and make for very up and down conditions at many sites. A moderate low pressure in the Great Basin and the Central Valley will pull these winds over most sites even though the ocean buoys winds are only in the mid teens.


Hedge: Saturday the North Pacific High drifts further away from us and the Central Valley & Great Basin thermal low pushes towards the coast causing the NW wind to fade and the pressure gradient becomes too weak for much wind at most sites. There is a CHANCE all of this could happen late Friday so watch for Updates. Mike
