Some East County residents could be fighting frost Monday night.
A frost advisory was issued from 10 p.m. Monday until 9 a.m. Tuesday in parts of the region where temperatures will be in the upper 40s.
The coldest temperatures are expected to occur in the inland valleys near the foothills of the mountains.
A winter weather advisory was in effect in the mountains until 10 p.m. Monday where people could see up to two inches of snow.
Temperatures Monday will be in the mid-50s inland, in the deserts and along the coast and in the upper 20s to lower 30s in the mountains.
"A few scattered showers could pop up, mostly this afternoon and evening," said NBC 7 Meteorologist Jodi Kodesh said. "The big story is the wind & cold temperatures."
Monday saw howling winds up and down the coast strong enough to force an airport weather warning at the San Diego International Airport. Forecasters expected sustained winds of 25 knots or greater and wind gusts of 30 knots or greater.
The warning expired at 4 p.m.
