A rare Particularly Dangerous Situation warning has been issued for Southern California as a powerful and potentially damaging Santa Ana wind event is expected.The National Weather Service announced a PDS warning will be in effect in Los Angeles and Ventura counties.

Santa Anas are the desiccating winds that are common in winter, blowing out of Nevada and Utah and into southwestern California. Carrying dry desert air, they push over the mountains in the Transverse Ranges and accelerate as they move downslope, howling into the canyons and valleys.

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

Now, Santa Ana winds are expected to sweep through the area early next week, accompanied by low humidity, meaning more potentially dangerous fire conditions. Here's what to expect over the weekend and into next week.
