Marine Weather and Tide Forecast for Samoa, CA

KEY MESSAGES

-Gusty north winds each afternoon along shore through mid week with gusts near 30 mph.

-Gradual warming and drying trend peaking Tuesday.

-Potential drizzle late week.

DISCUSSION
High pressure will has started to form over the eastern pacific and align with shore. This has helped create strong, persistent north wind along shore and across exposed areas of the interior. Coastal headlands and peaks have seen gusts in excess of 30 mph this afternoon. Temperatures have also warmed for the interior under clear skies with high temperatures in the low 80s.
Gusty north winds will persist near shore all through the week. High temperatures will peak around Monday and Tuesday with the warmest interior valleys reaching near 90. Models suggest a weak, night marine layer may form in protected coastal areas such as Humboldt Bay, but gusty north wind will help quickly mix out any clouds each day.

Looking at the extended forecast, most ensemble models show a quick moving trough clipping the area around next Friday, though compared to previous forecasts, most models now place it further north. As the trough approaches, more clouds will build in, helping to slightly cool conditions once again. A stronger marine layer is likely along shore around Thursday ahead of the trough. If the enough moisture can build along shore, another round of drizzle is likely, though chances for any wetting rain remain low (less than 15%) and mostly north of the area. Stronger high pressure and warming is likely behind the front. /JHW



AVIATION
Strong north winds have once again helped maintain VFR conditions all day today with the wind itself being the main aviation concern close to shore. There is slight potential for some MVFR to IFR ceilings (30% chance) this evening around Humboldt Bay, but most models maintain VFR conditions all night and through tomorrow. /JHW

MARINE
Near gale conditions have built in the outer waters today with very steep short period seas quickly building in response.
Winds will continue to creep upwards through Monday with more widespread gale conditions in the outer waters. Strong north winds and steep short period seas up to 12 feet will also push closer to shore in the inner waters by Monday afternoon. Hazardous and gale conditions will be prolonged, most likely persisting through at least Thursday when a very mild reprieve is expected. /JHW
