Orange County Under Cold Temperature Advisory Overnight Tuesday

ORANGE COUNTY, CA — The Orange County Health Care Agency has issued a cold weather advisory for much of the county as temperatures will significantly drop overnight Tuesday into Wednesday.

Inland, coastal and south Orange County cities can expect the colder-than-normal temperatures, the National Weather Service has forecasted, and temperatures in some areas will dip into the low 40s.

Officials are warning Orange County residents that temperature drops increase the chance of illnesses like hypothermia, as the human body begins to lose heat faster than it can be produced when exposed to cold temperatures.

Hypothermia is possible at temperatures above 40 degrees, officials said, if a person becomes chilled from rain, sweat or submersion in cold water.

"When prolonged exposure to very cold temperatures occurs, it is important to make certain that you are protected from hypothermia," said Dr. Regina Chinsio-Kwong, Deputy County Health Officer. "In addition, it is critical to check that seniors who live alone, your neighbors, pets and vulnerable populations are safe during this time."

The health agency is recommending community members wear warm clothing, and cautioning them against using a kitchen range or oven to heat their home.

If you're using a space heater, officials said, it should not be covered or placed within three feet of anything that could catch on fire — like bedding, drapes or furniture — and parents should ensure their children aren't left unattended near it.

If power is lost, don't use a gas-powered generator indoors, in a garage or near doors or windows where air may enter a home, the health agency said, to prevent carbon monoxide poisoning.
