The National Weather Service is forecasting morning frost on San Diego beaches. Big Sur, on the central coast, prepared for daytime highs almost 20 degrees below Boston’s. Even the snowbird haven of Palm Springs faced the possibility of freezing temperatures at night.
In addition, San Diego zookeepers turned up the heat for chimpanzees, tourists covered their hands on Hollywood walking tours, and some farmers broke out wind machines and took other steps to protect crops from freezing.
Freeze warnings were in effect in San Diego County valleys and this Saturday morning with lows in the 20s and 30s.
In Sonoma County, homeless shelters started handing out extra warm clothes on Friday to protect people from freezing overnight temperatures.
