PALMDALE (CBS) — Los Angeles County has opened up warming centers to help residents cope with an early cold snap.

Health officials warn that freezing temperatures elevate the risk of hypothermia for residents and pets who are without electricity or spending too much time outdoors.

The National Weather Service says the cold is also endangering unprotected and sensitive vegetation.

Temperatures are expected to stay cool throughout the week, especially during early morning hours when several freeze warnings will be in place.
