RIVERSIDE (CNS) – Extreme heat is expected in the Coachella Valley today and high temperatures are predicted for other parts of Riverside County, according to the National Weather Service.
High pressure will weaken today and cause a slight dip in temperatures, but conditions will strengthen on Tuesday and bring temperatures back up through Thursday, forecasters said.
The NWS issued an excessive heat warning that will last until 9 p.m. Thursday in the Coachella Valley.
High temperatures today will be 89 degrees in Riverside, 103 in the Coachella Valley, 99 in the San Gorgonio Pass near Banning, 75 in Idyllwild, 88 in Lake Elsinore, 85 in Temecula and 89 in Hemet.
Nighttime lows are expected to remain in the low- to mid-70s through Thursday in the Coachella Valley, 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 illness, and the NWS urged residents to drink plenty of fluids, stay out of the sun and check up on relatives and neighbors.
High temperatures in the Coachella Valley could reach 106 on Tuesday, then drop to 103 on Wednesday and Thursday, forecasters said. Highs in the Riverside metropolitan area could rise to the mid-90s through Wednesday.
