Red Flag Warning In Effect In San Diego County

BREAKING: Forecasters warn any fires that develop will spread rapidly.

SAN DIEGO COUNTY, CA – San Diego County is under a red flag warning from Monday morning through Thursday night with Santa Ana winds expected to slam Southern California and raise the risk of wildfires.

The red flag warning is in effect from 3 a.m. Monday through midnight Thursday across the region, with the strongest gusts expected along and below coastal mountain slopes and below passes and canyons.

"A red flag warning means that critical fire weather conditions are either occurring now or will shortly," the National Weather Service said in an advisory. "A combination of strong winds, low relative humidity and warm temperatures can contribute to extreme fire behavior."
