Scorching heat will retain its grip on Riverside County through at least Thursday, forecasters said Tuesday.
The National Weather Service extended excessive heat warnings for the Coachella Valley and Banning Pass until 8 p.m. Thursday. The warnings went into effect Tuesday morning.
A ridge of high pressure is sending temperatures soaring way past the century mark across the desert areas and the Banning Pass, with the mercury going well into the 90s in much of the rest of the county.
Temperatures were expected to range from 114 to 120 degrees in the Coachella Valley this week, and remain between 85 and 90 degrees overnight.
Palm Springs was expected to reach 118 degrees Tuesday, according to the NWS.
Banning Pass residents can expect temperatures from 105 to 115 degrees mid-week, forecasters said.
Meanwhile, a less severe heat advisory was also extended until 8 p.m. Thursday for the Riverside mountains and the western metropolitan region.
Temperatures were expected to range between 98 and 108 degrees in the valleys and Inland Empire, and in the 90s for the mountains.
“Extreme heat will significantly increase the potential for heat-related illnesses, particularly for those working or participating in outdoor activities. Warm overnight temperatures will compound heat stress for those without adequate cooling,” the weather service said.
People were advised to drink plenty of fluids, stay in an air-conditioned rooms, avoid the sun and check up on relatives and neighbors.
Cooling centers are open countywide, where residents without air-conditioning are able to take a break during daylight hours. A complete list is available at www.capriverside.org/cool-centers.
