SAN DIEGO (KGTV) -- As Santa Ana winds move out of the region, a freeze warning was issued for portions of San Diego County.

The National Weather Service issued a freeze warning for the county's valleys and deserts from midnight through 10 a.m. Friday. Overnight temperatures dropped into the low 30s, with a few areas seeing temperatures in the mid- to upper 20s.

The warning will affect cities including Escondido, El Cajon, San Marcos, La Mesa, Santee, and Poway.

NWS warns the temperatures have the potential to damage crops or vegetation and possibly outdoor plumbing.

"Take steps now to protect tender plants from the cold. To prevent freezing and possible bursting of outdoor water pipes they should be wrapped, drained, or allowed to drip slowly," NWS's alert read. "Those that have in-ground sprinkler systems should drain them and cover above-ground pipes to protect them from freezing."

The frigid temperatures come as San Diego County spent the better half of the week bracing for the worst of Santa Ana conditions. The high winds elevated the area's risk for wildfires, while several fires ignited in other areas of Southern California during the weather event.

Several San Diego communities did see public safety power outages to mitigate the risk for fires due to electrical equipment.

Though wind speeds tapered off with the expiration of the Red Flag warning, the risk for fires remains due to low humidity levels and very dry brush.
