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

...Elevated fire danger expected to continue through at least Friday
much of Southwest California due to weak to moderate offshore winds
with warm and dry conditions...

Northeast winds continue this afternoon but lighter with gusts
generally 30 mph or less focused across the mountains near the Los
Angeles and Ventura county border. Winds are expected to pick up
again later tonight across this region. Tuesday looks to be  similar
to Wednesday overall with slightly stronger winds. So brief
critical conditions are more likely for wind prone areas, especially
 across the western Santa Monica mountains. Lighter winds are
expected Wednesday and again Thursday with lingering dry conditions
away from the coast.

Otherwise and elsewhere away from the coast will likely experience
elevated fire weather conditions through at least late this week,
mainly due to weak offshore flow supporting hot and dry conditions
with very dry fuels in place. Widespread humidities in the teens are
 expected through the week with single digits possible in the hotter
 valleys at times. The elevated fire weather conditions will likely
support more frequent fire starts, the potential for large fires
with erratic fire behavior, including possibly long range spotting
in wind prone locations.

Lower confidence in the weather conditions for the upcoming weekend,
however continued a warmup focused across the valleys with locally
gusty northerly winds through wind prone mountains is the current
thinking.


...Discussion from Monterey...

...Red Flag Warning in effect for the East Bay Hills and the  North Bay
Hills through Wednesday afternoon...

Offshore flow combined with moderate to poor overnight relative
humidity recoveries will create dangerous fire weather conditions,
especially over the North and East Bay hills. North to Northeast
winds will increase overnight with peak gusts  to 30 mph around
sunrise Tuesday before subsiding. Another round  of gusty offshore
winds and low relative humidities will develop  again Tuesday night.
Daytime conditions will also be hot and dry  adding to fire weather
concerns. Conditions will gradually improve on Thursday as weak
onshore develops.

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