Heat Wave Blazes On In San Diego County

KPBS Staff
The sun shines over the I-5 South and the Sherman Heights neighborhood of San Diego on Feb. 21, 2021.

A heat wave will continue Saturday in San Diego County, but conditions are starting to shift slightly, and only the deserts will remain hot by Sunday, according to the National Weather Service.

The high pressure system over the Southwestern United States remains in place and will keep most of the region blazing hot through Saturday, forecasters said.

An NWS excessive-heat warning will remain in effect through 9 p.m. Saturday in the western valleys, 9 p.m. Sunday in the mountains and 9 p.m. Sunday in the deserts.

These conditions significantly increase the potential for heat-related illnesses, particularly for those working or participating in outdoor activities, authorities advised. People are advised to drink plenty of fluids, stay in air-conditioned rooms, seek out shade and check up on potentially at- risk relatives and neighbors.

Young children and pets should never be left unattended in vehicles — but particularly during such hot weather, when car interiors can reach lethal temperatures in a matter of minutes, the NWS cautioned.
