Frost Watch begins at 2am and ends at 9am
A frost watch has been issued for the San Francisco Bay Area for Wednesday morning, according to the National Weather Service, when temperatures in inland valleys could drop into the upper 20s.
Frost Watch begins at 2am and ends at 9am. Outside the inland valleys, temperatures can drop to 30 degrees.
People who are unprotected and marginally protected are at risk, weather officials said.
The low temperatures could kill plants and other plants and damage unprotected outdoor installations.
Residents are urged to start protecting outdoor plants and water pipes now. Pipes should be wrapped and deflated or allowed to drain slowly.
Those with underground sprinkler systems should drain systems and cover overhead pipes.
