SAN DIEGO - The 10News Pinpoint Weather Team says near freezing temperatures and areas of frost in San Diego County's deserts overnight and early Wednesday could kill uncovered sensitive outdoor plants.
Weathercaster Robert Santos said a frost advisory was issued for wind-sheltered desert areas including Borrego Springs, which was set to remain in effect until 9 a.m.

Mostly clear and very dry conditions will allow temperatures to fall into the 30s in the lower desert areas.
The National Weather Service advised that pets should be brought indoors, and sensitive plants may be damaged or killed if left uncovered.
However, Santos said that by Friday, temperatures will drop back to the low to mid 60s for the coast and valleys as a trough of low pressure moves into the Great Basin. The weekend will see a warm up into the low to upper 70s. The warming trend is forecast to last into early next week.
