A rare alert called a "Particularly Dangerous Situation" is in effect Wednesday for parts of fire-ravaged southern California. The National Weather Service initially issued the warning for Tuesday but extended it after Tuesday’s conditions were less hazardous than expected.

The most serious red flag fire weather warning has been issued by the NWS for swaths of L.A. and Ventura counties starting before dawn Tuesday.

The Eaton Fire burning just north of Los Angeles and the Palisades Fire that destroyed much of the seaside LA neighborhood of Pacific Palisades broke out Jan. 7 in conditions similar to what’s expected Wednesday. High winds last week pushed flames at remarkable speed and carried fire-sparking embers sometimes miles away.

The “particularly dangerous situation” was in effect for an area that includes parts of Los Angeles and Ventura counties.

LOS ANGELES (AP) — Millions of Southern Californians were on edge as a final round of dangerous fire weather was forecast for the region on Wednesday, along with a rare warning of a “Particularly Dangerous Situation” for an area near where two massive blazes have killed at least 25 and destroyed thousands of homes.

The strongest gusts are expected Tuesday morning and early afternoon, which will then be followed by a break in the evening.

The National Weather Service's Los Angeles page screams “Particularly Dangerous Situation (PDS)” in hot pink letters against a gray background in a rare warning aimed at seizing attention ahead of extreme wildfire risk that's predicted to start in Southern California at 4 a.
