Forecasters in Southern California expect to issue a 'particularly dangerous situation' red flag warning for the coming week as the Santa Ana wind forecast worsens.

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 National Weather Service offices across Southern California are warning residents of an increase in weather conditions that are conducive to rapid fire growth. Meteorologists are most concerned about conditions from Monday afternoon through Wednesday morning when winds will be at their peak and relative humidity will be low.

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.

After a weekend of reprieve allowing fire teams to continue making progress battling the deadly infernos burning in Los Angeles County, Southern California now faces another round of fire-fueling Santa Ana winds.

Residents and firefighters across Southern California braced for another round of fierce Santa Ana winds on Tuesday.
