High pressure over the desert southwest is expected to bring extremely hot weather to the Inland Empire and the Coachella Valley through the beginning of next week, prompting the National Weather Service to issue a heat advisory and an excessive heat warning for parts of Riverside County Friday.
The two weather warnings will be in effect from 10 a.m. Saturday until 8 p.m. Monday, though a high pressure system moving in from the east will bring scorching temperatures until Tuesday, according to the National Weather Service. The Coachella Valley is not expected to see significant cooling until Wednesday.
Temperatures of 113 to 118 are predicted in the desert region — where the excessive heat warning is in effect — every day through Monday, forecasters said. The less-serious heat advisory covers most of western Riverside County, where temperatures between 102 and 107 are expected.
The mercury is expected to reach 106 on Sunday in the Riverside metropolitan area, while Palm Springs could see highs of 116 on Saturday, Sunday and Monday.
No monsoonal moisture is expected with the system, but humid conditions could return early next week, forecasters said.
The NWS warned that several days of hot weather in the area “may cause heat exhaustion for those not prepared for excessive heat or for those who are active outdoors during the day.”
NWS officials urged residents to drink plenty of fluids and check up on elderly relatives and neighbors, especially those without air conditioning.
Residents were advised to take extra precautions when working or spending time outside, to reschedule any strenuous activities for the early morning or evening, to wear loose clothing whenever possible and drink plenty of water, forecasters said.
“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,” the NWS said.
Cooling centers are open daily across the county, providing residents who do not live in climate-controlled environments a free, cool space to relax until the evening hours.
