Heat wave continues in Riverside County

Excessive heat warnings are in effect today in parts of Riverside County until Saturday with hot conditions and high temperatures expected in the valleys, mountains, deserts and Inland Empire, the National Weather Service announced.

In the valleys and Inland Empire, temperatures are expected to reach between 95 and 100 degrees through Wednesday. Temperatures could reach 105 degrees from Thursday to Saturday.

In the mountains, temperatures below 5,000 feet are expected to be in the upper 80s through Wednesday. Hotter conditions with highs in the 90s to 100 degrees are expected Thursday through Saturday.

Excessive heat warnings are in effect until 8 p.m. Saturday in the valleys, mountains and Inland Empire.“Strong high pressure aloft will maintain hot weather inland into next week, with periods of high clouds,” according to the NWS. “Breezy west to southwest winds near the passes will keep fire weather conditions elevated.”

Excessive heat warnings will be in place until 11 p.m. Wednesday in the Coachella Valley and the San Gorgonio Pass, where high temperatures of 115 to 121 degrees are possible.
“The peak of the heat is expected this weekend with slight cooling for early next week,” according to the NWS. “High temperatures near 115 degrees could continue through the week. “… Drink plenty of fluids, stay in an air-conditioned room, stay out of the sun, and check up on relatives and neighbors. Young children and pets should never be left unattended in vehicles under any circumstances. This is especially true during warm or hot weather when car interiors can reach lethal temperatures in a matter of minutes.”

In addition to the heat, Riverside County is also coping with poor air quality, a result of multiple brush fires that have erupted since Friday. The South Coast Air Quality Management District issued a smoke advisory that will be in effect through at least 4 p.m. Sunday.

AQMD officials urged people to limit exposure by remaining in doors with windows and doors closed, avoiding strenuous physical activity, using air conditions rather than swamp coolers or fans that bring in outside air, avoiding burning wood in fireplaces and firepits, and wearing respirator masks while outdoors.
