Residents of the Napa Valley and other North Bay interior valleys can expect temperatures to drop below the freezing point in the early hours of Saturday, according to the National Weather Service.
The NWS has issued a freeze warning effective from 2 a.m. to 8 a.m., meaning that "sub-freezing temperatures are imminent or highly likely. These conditions will kill crops and other sensitive vegetation," according to the warning statement.
NWS forecaster Steve Anderson advised residents to make sure small outdoor pets have warm shelter, and to take precautions with plants that are sensitive to the cold.
"If they're potted plants, bring them inside if they're small enough, or throw a cover over them to keep the frost off if needed," he said.
