...Discussion from Los Angeles/Oxnard...

...RED FLAG WARNING IN EFFECT THROUGH FRIDAY MORNING OVER THE LOS
ANGELES AND VENTURA COUNTY MOUNTAINS, THE VENTURA COUNTY VALLEYS,
AND THE SANTA CLARITA VALLEY...

...FIRE WEATHER WATCH IN EFFECT THURSDAY MORNING THROUGH FRIDAY
MORNING OVER THE LOS ANGELES AND VENTURA COUNTY COASTS, AND THE SAN
FERNANDO VALLEY...

...WIDESPREAD ELEVATED FIRE WEATHER CONDITIONS WITH VERY DRY AIR
POSSIBLY THROUGH EARLY NEXT WEEK...

The extended period of offshore flow will continue into
Friday...focused over Los Angeles and Ventura Counties. Little
change expected through Wednesday with peak gusts in the 20 to
40 mph range in the wind prone areas. Strengthening is expected
Thursday into early Friday. The humidities will remain incredibly
dry with  extremely poor overnight recoveries nearly everywhere.
This will result in continued critical conditions into Friday,
especially Thursday afternoon and night when the winds peak. Santa
Barbara and  San Luis Obispo Counties will continue to see periods
of north to  east winds (gusts of 15 to 30 mph) through the week,
including areas near the Thomas Fire...resulting in elevated to near
critical fire  weather conditions. In addition, the air mass will be
fairly unstable above the Thomas Fire through Wednesday, resulting
in a greater risk for large fire plumes which will locally enhance
winds near the  fire.

Conditions will change Friday afternoon into Saturday as the flow
quickly shifts to more west to northwest, but this shift might
result in gusty winds through southern Santa Barbara County and the
I-5 Corridor. Humidities should improve some as well but will remain
dry. More offshore flow is likely Saturday night and Sunday.


...Discussion from Monterey...

High pressure will remain located over the district. Dry offshore
flow will continue with generally poor night-time  recoveries in the
mountains.

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