...CRITICAL FIRE WEATHER AREA FOR PORTIONS OF SOUTHERN CALIFORNIA...

The previous forecast (see below) remains on track, and only minor
adjustments were made to the Critical highlights based on the latest
observations and high-resolution guidance. Strong/gusty
northeasterly surface winds will gradually strengthen this afternoon
and persist into Day 2/Thursday, with the peak in these winds
expected during the overnight/early morning hours.

...Synopsis...
An amplifying mid-level trough will graze the West Coast today,
resulting in a tightening of the surface pressure gradient across
southern California, where dry offshore flow will continue to
support favorable wildfire-spread conditions. By late afternoon,
widespread 20+ mph sustained winds overlapping with 10-15 percent RH
will be likely across much of the southern California coastline.
Across terrain-favoring areas, localized instances of sustained 40
mph winds (perhaps with higher gusts) and near-single-digit RH are
possible, warranting the maintenance of Critical highlights this
outlook.
