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



...Synopsis...

A mid-level trough across the southwest U.S. will rapidly track

eastward toward the Southeast while surface high pressure persists

over the Great Basin through the period. Strong offshore flow will

persist from the Ventura Valley to the Laguna Mountains, with

widespread 20-30 mph sustained winds and 10 percent RH expected

during the day into early Wednesday morning, warranting the

maintenance of Critical highlights across much of the far southern

California shoreline. Furthermore, the latest high-resolution

guidance consensus shows sustained winds exceeding 40 mph,

coinciding with single-digit RH, from the Ventura Valley to the San

Bernardino Mountains, as well as the San Jacinto to Laguna Mountain

ranges, where Extremely Critical highlights were maintained. The

best chance for Extremely Critical conditions will be during the

morning into early afternoon hours.

Day 2 Fire Weather Outlook  

NWS Storm Prediction Center Norman OK

0157 AM CST Tue Jan 21 2025



Valid 221200Z - 231200Z



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



...Synopsis...

A surface pressure gradient will persist across southern California,

with some strengthening of the gradient likely by late Wednesday

afternoon as another in a series of mid-level troughs overspread the

Great Basin tomorrow (Wednesday). Another day of offshore flow

capable of supporting rapid wildfire spread is expected. By

afternoon peak heating, widespread sustained 20-30 mph wind speeds

are likely, along with RH dropping to at least the 10-15 percent

range. Locally higher wind speeds/gusts are also likely in

terrain-favoring areas. Anywhere from the Ventura Valley region to

the Laguna Mountains may experience the aforementioned

meteorological surface conditions, necessitating the introduction of

Critical fire weather highlights this outlook.
