An uptick in Santa Ana winds Wednesday afternoon through Thursday, combined with critically dry vegetation and low humidity, will result in elevated to locally critical fire weather conditions in San Diego County through late Thursday.

The National Weather Service has issued another rare Particularly Dangerous Situation warning in anticipation of Monday's Santa Ana wind event.

After a much quieter weekend, Southern California is experiencing a major shift in the weather pattern. The winds will peak Monday evening and overnight but extend into Tuesday morning.

With the strongest gusts expected on Tuesday, extreme fire condition threats will prevail until midweek, L.A.-area fire chiefs say.

Meteorologists said there was a chance the winds would be as severe as those that fueled the Palisades and Eaton fires, but that different locations would likely be affected.

Nearly two weeks after the start of two of the most devastating wildfires to hit the Los Angeles area, Southern California is under an extreme fire risk warning again.

President Donald Trump will visit southern California this week amid looming winds and threats of new flames with tens of thousands of acres torched and buildings destroyed, according to reports.

Millions of California residents were placed under a red flag warning through Thursday amid threats of further fires with looming winds in the forecast, according to multiple reports.

The Santa Anas are expected to be most powerful Monday night into Tuesday. Fire services across the region say they are ready.

California Governor Gavin Newsom has deployed fire engines, water-dropping aircraft and hand crews across the region—to enable a rapid response if a new fire does break out, according to The Associated Press.

"A strong Santa Ana Wind event is expected to develop Monday and last through at least Tuesday," the National Weather Service said.
