Dry and warm gusts blowing in from the desert have elevated the wildfire risk in Southern California to critical, several weeks after deadly flames tore through wine country to the north.
The strongest Santa Ana winds of the season threaten more than 14,000 square miles covering a population in excess of 19.9 million, according to the U.S. Storm Prediction Center in Norman, Okla. That includes Los Angeles, San Diego and San Bernardino. The winds are expected to last through Thursday.
“Fire does very well in those conditions,” said Richard Bann, a forecaster at the U.S. Weather Prediction Center in College Park, Md. “The fuels, the grasses, anything that might have been growing, they are cured and ready to burn. You get any of these conditions and a fire starts.”
Winds could pick up to 40 to 60 miles per hour, with very low humidity bringing on the “potential for the strongest, longest duration Santa Ana event of the season,” the National Weather Service said. Dust storms could kick up and power disruptions are possible as winds knock down lines and trees.
