...FIRE WEATHER WATCH IN EFFECT FROM WEDNESDAY EVENING THROUGH THURSDAY
MORNING FOR GUSTY WINDS AND LOW RELATIVE HUMIDITY OVER THE  SANTA
BARBARA COUNTY MOUNTAINS AND SOUTH COAST...

...MODERATE TO STRONG NORTH WINDS WEDNESDAY AFTERNOON INTO
THURSDAY...

...CRITICAL CONDITIONS WITH GUSTY OFFSHORE FLOW POSSIBLE THURSDAY
AND FRIDAY...

Humidities will increase 10 to 20 percent on Tuesday, and more into
Wednesday as a low pressure system sweeps into Nevada and  onshore
flow strengthens. Interior areas like the Antelope Valley will see
gusty winds on Tuesday with gusts up to 40 mph. There is a chance
for very light rain north of Santa Barbara, and a marine layer to
the south. By Wednesday afternoon and evening, confident  that the
flow will shift to northerly and strengthen over the wind  prone
areas including the Santa Ynez Range and the Thomas Fire, as  well
as the I-5 Corridor. Peak wind gusts will likely exceed 40 mph,
with gusts to around 60 mph possible which would be similar to
Saturday. Humidities will be above 15 percent, but a Fire Weather
Watch will be issued due to the extremely dry fuels and the strong
winds which will expand and drive any active fire areas. The winds
will become northeasterly Thursday and Friday and shift focus to Los
 Angeles and Ventura Counties and out of Santa Barbara County.
Drying  is likely during this time and Red Flag conditions are
possible, and  a Fire Weather Watch will be considered on Tuesday.
High uncertainty  remains for the Christmas weekend, but significant
offshore flow and  very dry conditions are possible. Other than
Wednesday, no rain  chances for the next 7 days.


...Discussion from Monterey...

Light offshore flow will continue through tonight with continued low
RH values across the region. Winds will turn  onshore Tuesday ahead
of an approaching cold front which will  result in slightly cooler
temperatures. The front is forecast to  move through Tuesday night
into Wednesday spreading light rain  from north to south across the
fire district. The North Bay is forecast to receive around a tenth
to two tenths on an inch, highest totals in the hills. Areas to the
south will likely only receive a few hundredths. Brisk northerly
winds will fill in behind the front as high pressure returns to the
region. Cool and dry conditions will continue through the remainder
of the  week and through Christmas.

Note : All winds are 20-foot Winds Unless otherwise specified.
Thunderstorms imply strong, gusty and erratic winds.
