Three wildfires broke out in quick succession overnight and into early Tuesday in northern San Diego County, California.

The National Weather Service issued its most serious red flag warning for parts of Los Angeles and Ventura counties this week as the fires still burn

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.

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.

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

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 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.

Santa Ana winds return to Southern California from Monday to Tuesday, once again raising fire danger concerns.

There are no evacuation orders in place now for the Eaton and Sepulveda Fires in LA County, the Clay Fire in Riverside County or the Laguna Fire in Ventura County. Evacuation orders were in place for areas near the Laguna Fire but have since been changed to evacuation warnings, according to Cal Fire.

As wildfires continued to burn in Los Angeles, three fires broke out in San Diego County, prompting evacuation orders and warnings.

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

The Palisades and Eaton wildfires also continue burning in the Los Angeles area, leaving parts of Southern California with devastating fire damage.
