...CRITICAL FIRE WEATHER AREA FOR PORTIONS OF FAR SOUTHERN CA...

...17z Update...
The prior forecast remains valid with only minor changes to the
Elevated area over parts of the LA Basin. Morning observations show
offshore gusts of 30-40 mph are ongoing across terrain-favored areas
of the LA Basin. This is expected to gradually diminish through the
morning and afternoon as the offshore pressure gradient and easterly
flow aloft weaken. Still, low humidity (RH values from 10-20%) and
the strong gusts appear likely to support a continued fire-weather
threat into this afternoon. The most likely corridor for sustained
elevated to near-critical conditions will remain over the
terrain-enhanced features of the western LA Basin and farther south
into the San Jacinto to Laguna mountain ranges. Fire concerns should
then abate overnight as upper-level support and offshore gradients
weaken further. See the prior discussion for more information.

.PREV DISCUSSION... /ISSUED 0140 AM CST Fri Jan 10 2025/

...Synopsis...
A series of positively tilted mid-level troughs will progress
southeastward across the western and central CONUS today, supporting
the maintenance of surface high pressure across the Inter-mountain
West. Dry offshore winds should continue off of the southern
California coastline through at least the morning hours. However,
the pressure gradient should diffuse through the day as the first in
a series of mid-level troughs moves away from southern California.
Elevated to Critical dry and windy conditions should be most
prevalent during the morning, and will wane during the afternoon
hours. The best chance for any Critical conditions (i.e. 20+ mph
sustained offshore winds with 15 percent or less RH) will be across
the San Jacinto to Laguna mountain ranges.
