Near-freezing temperatures, frost possible in parts of San Diego County's valleys, deserts overnight

SAN DIEGO - Near-freezing temperatures and areas of frost are possible overnight in parts of San Diego County's valleys and deserts, and sensitive outdoor plants could be killed if left uncovered, meteorologists said Sunday.

The National Weather Service scheduled a frost advisory from 10 p.m. Sunday to 9 a.m. Monday for the inland valleys and deserts, where temperatures are expected to fall into the 30s through early Monday.

Frost will be possible in colder, wind-sheltered areas, forecasters said.

Strong, gusty northeast winds are also expected to develop tonight near the coastal foothills and stick around through early Tuesday.

Sunday's lows are expected to be between 34 and 44 degrees along the coast, 35-40 in the deserts, 31-40 degrees in the valleys and just 22-30 degrees in the mountains, according to the NWS.
