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.

A "Particularly Dangerous Situation" warning remains in effect as strong winds cause extreme fire danger in Southern California.

Critical fire conditions are expected to continue through Friday. But rain could be on the way this weekend. Here's what to know.

The Santa Ana winds are dry, powerful winds that blow down the mountains toward the Southern California coast. The region sees about 10 Santa Ana wind events a year on average, typically occurring from fall into January. When conditions are dry, as they are right now, these winds can become a severe fire hazard.

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.

One of the biggest stories of 2025 thus far has been the wildfires in California. A common occurrence in that state, wildfires are often fueled by a combination of drought and terrain. The terrain allows for the development of Santa Ana winds that cause any fire to spread very quickly.

Katabatic winds? Adiabatic compression? Time for a thermodynamics lesson! The record lack of rain has also made this Santa Ana event different.

The Santa Ana winds are expected to pick up again this week, making the Palisades and Eaton fires, among others, more difficult to contain as they continue to rage in Southern California.
