Southern California will feel the remnants of a tropical storm Thursday as extreme heat settles in for an extended stay.
Thunderstorms are possible in mountain areas, including the Lake Fire zone north of Los Angeles, and triple-digit temperatures are expected. The ridge of high pressure will continue building over the southwestern United States through Monday, ushering in the scorching heat.
“If you have to do your workout outside, do it early in the day,” said NBC4 forecaster Belen De Leon.
Moisture from Elida — which has weakened to a tropical depression and is currently centered roughly 700 miles south of San Diego — will create a chance of thunderstorms. Light rain was reported early Thursday in parts of Ventura County and the San Fernando Valley.
“It’s brought in the clouds, it’s brought in that moisture and higher humidity,” said De Leon. “This is an extended period of very high temperatures.”
Air quality will be unhealthy today for sensitive individuals in the East San Gabriel Valley, West San Fernando Valley and the San Gabriel Mountains, according to the South Coast Air Quality Management District.
An excessive heat warning will go into effect Friday and continue into early next week for most of Southern California. Widespread triple-digit heat is in the forecast through the weekend.

The Apple Fire, which has burned 33,424-acres in the San Bernardino National Forest including a portion of the San Gorgonio Pass near Banning, was 60% contained as of Wednesday night. U.S. Forest Service officials said the gusty winds and increasing temperatures through the weekend could pose a challenge to containment efforts.
