Frostbite is a risk in such conditions, and public health officials say people should only use approved heaters, like electric or natural gas heaters or fireplaces, to heat their homes to avoid carbon monoxide poisoning.

“There are places where people can go to stay warm, such as shelters or other public facilities,” Los Angeles County Health Officer Dr. Muntu Davis said. “We also want to remind people not to use stoves, barbeques or ovens to heat their homes due to the risk of carbon monoxide poisoning.”

The National Weather Service is also forecasting unusually high tides starting Sunday. High tides of at least 7 feet are predicted for the LA Harbor, and surf is expected to build 3 to 5 feet along Los Angeles and Ventura county coasts.

“There will be a threat of minor tidal overflow due to astronomical high tides combined with the higher surf,” the NWS statement said. “Some usual vulnerable locations could see some minor ocean water inundation during the peak of the high tides, as well as some minor beach erosion.”
