...ELEVATED GRASS FIRE DANGER TODAY AND MONDAY WITH GUSTY WINDS
ACROSS GAPS AND PASSES...
.DISCUSSION...Another round of gusty NW winds this afternoon.
Good moisture remains across much of the region with a reinforced
marine layer thanks to the robust onshore flow. However, areas
above about 2,000 feet will see very limited overnight recovery,
and far inland areas will be very dry during the afternoon hours.
The strongest gusts will occur mostly across our favored gaps,
passes, and valleys, especially Altamont Pass and the Salinas
Valley. Wind begins to ease later this evening.
Note : All winds are 20-foot Winds Unless otherwise specified.
Thunderstorms imply strong, gusty and erratic winds.
