Spot Forecast for Department of State Hospitals - Napa Vegetation...Department of State Hospitals - Napa
National Weather Service San Francisco CA
525 PM PST Mon Nov 24 2025

Forecast is based on ignition time of 0800 PST on November 25.
If conditions become unrepresentative, contact the National Weather
Service.

.DISCUSSION...Quiet weather is expected this week as high pressure
builds across the region. Winds will stay light and offshore
through the forecast period with winds gradually transitioning
from more southerly on Tuesday to more easterly by Wednesday.
Probabilistic guidance indicates gusts greater than 10 mph are not
anticipated during the forecast period. Overnight humidity
recoveries remain excellent while continuing light offshore flow
will result in drier, but still fair, daytime humidity retention.
Building high pressure will result in a shallow marine layer
(approx. 500 ft) confined directly along the coastline.
