...EXTREMELY CRITICAL FIRE WEATHER AREA FOR PORTIONS OF THE SOUTHERN
CALIFORNIA COAST...
...CRITICAL FIRE WEATHER AREA FOR THE SOUTHERN CALIFORNIA COAST...

...Synopsis...
Critical to extremely critical fire weather conditions are expected
Tuesday morning along the southern California coast. An unseasonably
strong surface high across the northern Great Basin will maintain a
robust offshore pressure gradient along the southern CA coast for
much of Tuesday and into early Wednesday (see the current D1 Fire
Outlook for additional details regarding the synoptic regime).
Recent guidance continues to suggest that the LAX-DAG gradient
should peak sometime during the 12-17 UTC period Tuesday morning at
around -9 to -10 mb. A gradient of this magnitude typically supports
wind gusts within the coastal terrain between 50-70 mph, though
localized stronger gusts appear possible based on some high-res
solutions. 

By early Tuesday morning the offshore flow regime will be well
established with 12 hours of preceding downslope warming/drying. Not
only will this support more widespread areas of single-digit RH
values (and extremely critical fire weather conditions), but should
also promote rapid curing/drying of 1 and 10-hour fuels.
Consequently, the greatest fire weather threat will likely emerge
Tuesday morning. Recent ensemble guidance and high-res deterministic
solutions suggests extremely critical conditions will be most
widespread across western Los Angeles and eastern Ventura counties
within the San Gabriel and Sierra Madre mountains, though localized 
extremely critical conditions will be possible further south along
the southern CA coast.
