As the South prepped for snow and more cold starting Wednesday, residents in Southern California faced off with hurricane-strength winds.

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.

The intense and fast-moving fires that have cut a path of destruction through the suburbs of Los Angeles, killing at least two people, are being driven by the region's powerful Santa Ana winds, with gusts that in some cases surpass hurricane-strength.
