A rare Particularly Dangerous Situation warning has been issued for Southern California as a powerful and potentially damaging Santa Ana wind event​ is expected.

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

Not only do these winds accelerate the speed and spread of the fires, they also affect how the fires are fought. The strong winds can make it dangerous to fly aircraft used for containing the fires.

Southern California will continue to face "dangerous fire weather conditions" including strong Santa Ana winds and extremely low humidity through later this week, forecasters said Tuesday.

Just a few years after the ozone hole was detected via satellite, the industrialized nations of the world, meeting in Montreal in 1987, adopted what is known as the Montreal Protocol.

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.

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

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.

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

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.
