GORMAN, Calif. (KABC) -- After a mostly mild winter, a big chill has come to Southern California this week, with Monday being the coldest day.
A winter weather and wind advisory is in effect in some areas, with wind gusts up to 50 to 60 mph expected in the mountains and deserts. A hard freeze warning is in place for the valleys and Ventura County.
Temperatures in the mountains are expected to stay in the 20s on Monday and Tuesday, and drop as low as 10 degrees overnight.
Areas like the windy Tejon pass are dropping down to the lowest temperatures of the year and travelers are already feeling the chill.
"It just cuts through your skin," said Kathy Ricossa, of Anaheim. "It feels like it's cutting right through. Biting."
