An uptick in Santa Ana winds Wednesday afternoon through Thursday, combined with critically dry vegetation and low humidity, will result in elevated to locally critical fire weather conditions in San Diego County through late Thursday.

The National Weather Service has issued another rare Particularly Dangerous Situation warning in anticipation of Monday's Santa Ana wind event.

As wildfires continued to burn in Los Angeles, three fires broke out in San Diego County, prompting evacuation orders and warnings.

Meteorologists said there was a chance the winds would be as severe as those that fueled the Palisades and Eaton fires, but that different locations would likely be affected.

With the strongest gusts expected on Tuesday, extreme fire condition threats will prevail until midweek, L.A.-area fire chiefs say.

Officials warn the peak of the Santa Ana winds have been pushed back by about a day from the original timeline.

The Santa Anas are expected to be most powerful Monday night into Tuesday. Fire services across the region say they are ready.

The winds fueling Southern California wildfires form when a high-pressure system develops over the Great Basin in Utah and Nevada

LOS ANGELES (AP) — Parched Southern California was forecast to face more dangerous winds on Wednesday but could get some badly needed rain this weekend, dampening the prospects of another round of deadly wildfires though even a small amount of precipitation could could create new challenges like toxic ash runoff.

A fresh round of deadly 100mph Santa-Ana winds will hit western states, raising America’s wildfire threat back to ‘critical’. As much of the country freezes in a minus-20C snow blast, warm, dry winds along the Pacific coast threaten ‘rapid fire spread and extreme fire behaviour’.

The NWS said up to 4 inches (10 centimeters) of snow fell in the Houston area. Texas transportation officials said more than 20 snowplows were in use across nearly 12,000 lane miles in the Houston area, which lacks its own city or county plows.
