Cold Weather Advisory Issued In RSM This Week: What To Know

RANCHO SANTA MARGARITA, CA — Orange County health officials advised residents to bundle up this week, as a Cold Temperature Advisory was issued for inland and coastal cities through Friday.

The advisory comes after the National Weather Service forecasted cold overnight temperatures starting Monday and ending Friday. Overnight temperatures in some areas of the county will dip to the low '40s, Orange County Health Care Agency officials said.

In Rancho Santa Margarita, residents can expect temperatures ranging from the low-'60s in the daytime to the high-'40s in the nighttime through the week, according to Accuweather.

County health care officials warned the public of an increased risk of cold-related illnesses, such as hypothermia, especially for those who are more sensitive to extreme weather changes.

Hypothermia occurs often at very cold temperatures, but it can also occur at cool temperatures above 40-degrees. Residents were encouraged to check in on loved ones while the cold spell stays in the county.

"When prolonged exposure to very cold temperatures occurs, it is important to make certain that you are protected from hypothermia. In addition, it is critical to check that seniors who live alone, your neighbors, pets and vulnerable populations are safe during this time," Dr. Regina Chinsio-Kwong, county health officer and OC Health Care Agency Chief Medical Officer, said in a statement.
