...RED FLAG WARNING IN EFFECT FROM 11 AM TO 8 PM PDT MONDAY FOR  DRY
CONDITIONS AND GUSTY NORTHERLY WINDS FOR INTERIOR HIGH  ELEVATION
PORTIONS OF NAPA COUNTY...

...ELEVATED FIRE WEATHER CONDITIONS ELSEWHERE THROUGHOUT TUESDAY...

Breezy to gusty dry northerly flow will continue to impact the
region throughout Tuesday. Fire weather conditions  will be most
critical away from the coast and over the higher  terrain,
especially the North Bay Interior Mountains where a Red Flag Warning
is in effect from 11 AM to 8 PM Monday. Conditions  gradually
improve by Wednesday. High pressure begin to build over  the region
for the second half of the week kicking off a marked  warming and
drying trend.

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

......RED FLAG WARNING IN EFFECT UNTIL 3 PM PDT MONDAY FOR GUSTY
NORTHWEST TO NORTH WINDS AND LOW RELATIVE HUMIDITY FOR THE
INTERSTATE 5 CORRIDOR AND VENTURA COUNTY MOUNTAINS...

...ELEVATED TO BRIEF CRITICAL FIRE WEATHER CONDITIONS THROUGH
TUESDAY FOR REMAINING INTERIOR AREAS AND SOUTHERN SANTA BARBARA
COUNTY DUE TO GUSTY WINDS WITH WARM AND DRY CONDITIONS...

Strong northwest to north winds will remain widespread across
interior Southwest California through Monday evening, with the
strongest wind surge expected tonight. The combination of a long
duration of strong northwest to north winds and low relative
humidity has resulted in a Red Flag Warning until 3 pm Monday for
the I-5 corridor and the Ventura County mountains as conditions will
remain favorable for large fire growth across the Post Fire complex.
Wind gusts in this region are expected to be 40-55 mph this
afternoon, increasing to 60-70 mph tonight, and 35-50 mph on Monday
into Monday evening. By late Monday night into Tuesday morning, the
wind is expected to shift to the northeast with gusts up to 35 mph
near the Post Fire. Daytime humidity levels in this region are
expected to fall to between 15-25 percent today and  Monday, lowest
in downslope flow favored areas. By Tuesday, humidity levels will
potentially fall to less than 10 percent. As a result, there is a
40 percent chance of the Red Flag Warning being extended into Monday
night and Tuesday.

Elsewhere across the region, northwest wind gusts of 30 to 50 mph
will be common at times through Monday evening across the interior
and southwest Santa Barbara county. Isolated gusts to 60 mph will be
likely in the strongest periods of wind across the western Santa
Ynez Range and adjacent western Santa Barbara County South Coast,
especially near Gaviota and Refugio in the evening and overnight
hours in conjunction with Sundowner wind enhancements. Meanwhile, a
warm and dry air mass will remain in place, with widespread 8 to
15 percent humidities across the interior today, and 12 to 20
percent on Monday. Poor overnight recoveries in the foothills are
also expected. The warm and dry air will continue to descend into
some coastal foothills today, including portions of southern  Santa
Barbara County. With the northeast winds gusting between 25 and
45 mph and very low humidities falling to between 5 and 10 percent
on Tuesday, the elevated to brief critical fire weather conditions
have been extended across the interior through Tuesday. There is an
increased risk for fast-growing grass fires over much of the area,
that could transition into wildfires where the fuel beds are most
abundant and dry.
