SAN DIEGO — Gusty winds will hit parts of San Diego County Monday morning, while temperatures are expected to drop Monday evening, prompting the National Weather Service to issue a freeze warning for parts of the region.

A high wind warning will remain in effect until noon Monday in the county mountains and deserts. Winds are expected to be between 30 and 45 mph in the mountains, with gusts possibly reaching 75 mph, according to the NWS. Winds in the deserts will be between 20 and 30 mph, with 55 mph gusts possible.

Weather officials warned that the wind gusts could be strong enough to blow around unsecured objects and knock down tree limbs, potentially causing power outages. Conditions will also be hazardous for high-profile vehicles traveling on highways through mountain passes, especially Interstates 8 and 15. A freeze warning has also been issued for the county's valleys and deserts, including the cities of El Cajon, Escondido, La Mesa, Poway, San Marcos and Santee. The warning will be in effect from 10 p.m. Monday until 10 a.m. Wednesday.

Sub-freezing temperatures as low as 30 degrees Monday night and as low as 25 degrees Tuesday night will be possible in the deserts, according to the NWS. Sub-freezing temperatures as low as 28 degrees Monday night and as low as 25 degrees Wednesday night will be possible in the valleys. "Frost and freeze conditions will kill crops, other sensitive vegetation and possibly damage unprotected outdoor plumbing," weather officials said.
