Brad Baker Coho ho ho weather August 30, 2014
Except a couple of boats that are departing later, it looks as though the remaining fleet still on the water is closing in on San Francisco. I'll continue weather reports through Monday unless everyone has reached SF by before then. All the boats appear to be in California Waters so I will confine my reports to that vicinity.
There are no significant changes to the forecast. The pacific high pressure is moving in from the west combining with the inland thermal low. The strongest wind field has been blowing south of Cape Mendocino. As the high builds this wind field will expand further North and build with the strongest winds in the usual location between the capes. It does appear that the wind field will extend well south of SF though for moderate to strong NW winds all the way to SF. In general the gradients are going to tighten and it will be pretty darn windy at times in these Northern California waters.
