The hottest temperatures of the week are expected on Wednesday throughout San Diego County,  but relief will arrive this weekend, according to the National Weather Service.

High pressure over Baja California will keep temperatures warm through Friday throughout the county, then temperatures will drop quickly and return to around seasonal average on Sunday, forecasters said.

A heat advisory is in effect until 9 p.m. Friday in the western valleys and an excessive heat watch will also last until 9 p.m. Friday in the deserts.

High temperatures on Wednesday are forecast to reach 82 degrees near the coast, 90 inland, 96 in the western valleys, 95 in the mountains and 110 in the deserts.

With a statewide stay-at-home order in effect, there will be little places for residents to go to beat the heat. "Cool Zones" that are typically open at libraries and other public areas are closed through at least May amid a public health order. The beaches are open in San Diego County but have restrictions that allow them to be utilized for exercise only.

The county advises residents to instead stay cool indoors. SDG&E and the county are partnering to provide free electric fans to low-income families.

To be eligible, a resident must not have access to an air-conditioned space at their home or apartment building. To learn more about the fan program or to request a fan, call Aging & Independence Services at (800) 339-4661.

Nighttime lows are expected to remain in the low- to mid-70s through Saturday in the county deserts, meaning the minimal cooling at night could pose a health risk to those who don't have access to air conditioning because the body needs time to cool down from the day's heat, according to the NWS.

The combination of hot days and warm nights is expected to increase the threat of heat-related illness, and NWS officials urged residents to drink plenty of fluids, stay out of the sun and check up on relatives and neighbors.

Also, young children and pets should be never be left unattended in a vehicle, with car interiors able to "reach lethal temperatures in a matter of minutes," according to the NWS.
