Excessive Heat Prompts Warnings in LA Valleys, Inland Empire

Temperatures in the Santa Clarita, San Fernando and San Gabriel valleys were expected to range between 103 and 110 degrees Sunday

A slew of heat advisories, excessive heat warnings and fire watches were in place Sunday as temperatures reached triple digits in the LA valleys and Inland Empire over the weekend.

Temperatures in the Santa Clarita, San Fernando and San Gabriel valleys reached the triple digits Sunday. Temperatures in Riverside, San Bernardino and Van Nuys remained in the 90s after sundown.

The National Weather Service issued an excessive heat warning for the LA and Ventura county valleys and Santa Monica Mountains that was expected to last until 7 p.m. Tuesday. A red-flag warning was also in effect through 9 p.m. Tuesday for the mountains of LA and Ventura counties. Other areas will have an elevated fire danger.

“The combination of heat and humidity will create a dangerous situation in which heat illnesses are possible,” according to a statement from the National Weather Service.

A heat advisory was issued in San Bernardino and Riverside counties as temperatures were expected to push past 100 degrees in mountain areas. Residents were advised to stay cool indoors and refrain from strenuous activity.

“Anyone overcome by heat should be moved to a cool and shaded location. Heat stroke is an emergency -- call 911,” NWS stated.

The scorching heat also brought with it concerns of fire potential in the Los Padres and Angeles national forests. Winds gusting up to 20 miles per hour were expected to be paired with low humidity and temperatures in the 90s to low 100s in lower mountain areas.

“Any fire ignition will have the potential for large plume dominated growth over the mountains,” according to NWS.
