URGENT - FIRE WEATHER MESSAGE
National Weather Service Los Angeles/Oxnard CA
952 AM PST Sat Dec 7 2024
...FIRE WEATHER WATCH IN EFFECT FOR MUCH OF LOS ANGELES AND
VENTURA COUNTIES 10 AM MONDAY UNTIL 6 PM WEDNESDAY DUE TO
MODERATE TO LOCALLY STRONG SANTA ANA WINDS AND VERY LOW
HUMIDITIES...
.As surface high pressure builds into the Great Basin, Santa Ana
winds are expected to increase late Monday morning or afternoon,
then peak Monday night into Tuesday night. Offshore winds are
expected to diminish some by Wednesday, but very dir will
persist. With the strong likelihood of widespread single digit
humidities with this event, confidence is increasing for a long
duration Red Flag event. In addition, there is the potential for a
high end Red Flag event across some of the windiest areas Monday
night through Tuesday night, as localized wind gusts of 55 to 65
mph could overlap with single digit humidities across the western
San Gabriels, Santa Susanas, and western Santa Monicas.

COUNTIES...
* WINDS...Santa Ana winds expected to increase sharply late Monday
