Triple digit temperatures are in the forecast for Riverside County Monday and it will remain hot all week, according to the National Weather Service.
Temperatures in Riverside County valleys will potentially reach 106 degrees by Tuesday and in the mountains at elevations below 5,000 feet up to 100.
The National Weather Service’s Monday forecast calls for highs of up to 114 degrees in the Coachella Valley, up to 104 degrees in the Riverside County valleys and the Inland Empire and up to 100 degrees in the Riverside County mountains.
“Extreme heat will significantly increase the potential for heat related illnesses, particularly for those working or participating in outdoor activities,” NWS forecasters warned. “Know the signs and symptoms of heat exhaustion and heat stroke. Wear lightweight and loose fitting clothing when possible and drink plenty of water.”
Lightning strikes were reported in the Riverside County deserts Sunday morning.
“[10 AM Radar]: Showers and isolated t-storms continue to move northwestward this morning. Lightning strikes have been reported in the deserts in San Diego County and Riverside County in the past few hours, so please use caution and remember if thunder roars, go indoors,” the National Weather Service’s San Diego office tweeted.
Forecasters said the sweltering conditions will likely linger through next weekend as well.
