Temperatures will remain high at 5 to 10 degrees above normal in San Diego County on Sunday as the weekend heat wave continues through Wednesday, according to NWS.

This raises fears of heat-related illnesses and wildfires, said forecasters.

High temperatures during the weekend have been 76 to 81 degrees along the coast, 81 to 86 degrees inland, 84 to 89 in the western valleys, 87 to 92 near the foothills, 91 to 98 in the mountains and 108 to 113 in the deserts, according to the National Weather Service.

Building high pressure is expected to push temperatures a couple degrees higher in much of the county on Sunday.

“We will begin feeling the heat on Saturday,” said a report from the weather service. “The forecast for Sunday elevates the risk for heat-related impacts to moderate levels across much of our region.”

The heat is expected to continue into next week, according to the NWS, and forecasters said heat advisories may be necessary. Lifeguards said they expected large crowds today at San Diego County beaches — including ones in Del Mar and Encinitas — as residents sought relief from the toasty temps. Lt. Rich Stropky of the San Diego Lifeguard department said that despite the crowds, there were no unusual incidents on Saturday.

Forecasters advised residents to avoid potentially serious heat-related ailments by staying hydrated, avoiding unnecessary outdoor labor and checking on neighbors and relatives.

Authorities also warned against leaving people or pets in parked cars, which can quickly become death traps in high heat.
