Temperatures reached 116 degrees in parts of the Coachella Valley today, and thunderstorms were scattered throughout the San Jacinto Mountains, according to the National Weather Service.
A flash flood watch was in effect today in the Inland Empire until 7 p.m. because of the potential thunderstorm activity, as well as an excessive
heat warning for the entire area.
“These storms will contain frequent cloud-to-ground lightning, local wind gusts to 45 mph, small hail and heavy rain capable of flooding normally dry creeks and low-lying areas,” the forecast said.
By mid-afternoon today, weather radar showed thunderstorms in the San Jacinto and San Bernardino Mountains. The storms were predicted to continue at least until 4 p.m., according to a short-term forecast.
Portions of the Inland Empire along a line from Lake Elsinore toward Hemet could also have thunderstorm activity with heavy rain and Riverside County valleys could also be affected, according to the NWS.
The weather service also issued an excessive heat warning in the Coachella Valley that will remain in effect until 10 p.m. Monday. Predicted
daytime highs could reach 118 degrees in some areas today and 116 degrees on Monday.
“Hot days followed by warm and humid nights can limit the body’s ability to keep cool,” the NWS warned. “Visiting hikers and campers
unfamiliar with intense desert heat are especially susceptible to heat stroke or heat exhaustion. Pets are also susceptible to this heat as well.”
The NWS advised to take extra precautions in dealing with the heat, such as rescheduling strenuous activities to early morning or early evening, wearing lightweight and loose-fitting clothing when possible and drinking plenty of water.
