132 AM PDT Sun Aug 31 2025
...ELEVATED FIRE WEATHER THREAT IN THE INTERIOR MOUNTAINS THROUGH
THE WEEKEND DUE TO LOW RH AND MODERATE AFTERNOON BREEZES...
.DISCUSSION...Large scale sinking air, compressional warming and
drying aloft, a strong low level temperature inversion coupled
with diurnal late August solar warming will continue to produce
hot and dry conditions over the interior today and Monday.
Conditions remain cooler along the immediate coast due to a
shallow marine layer and generally light to locally moderate
afternoon sea breezes. Above the shallow marine layer very low
daytime humidities and poor overnight recoveries have persisted
just away from the immediate coast. Winds remain onshore, but
breezy afternoon winds will elevate the fire weather threat in the
interior mountains, especially through favored gaps and passes.
Note : All winds are 20-foot Winds Unless otherwise specified.
Thunderstorms imply strong, gusty and erratic winds.
