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 stiff Santa Ana winds that stoked a short-lived but dangerous wildfire Monday in Poway were expected to be flat-out wicked before dawn Tuesday in San Diego’s backcountry, where something as minor as the heat from a car muffler could spark a major blaze,

Parts of Los Angeles, Orange, Riverside and San Bernardino counties all will be under a red flag warning beginning on Monday morning, the NWS said. The strongest Santa Anas are expected Tuesday morning.
