Hollywood Heat Warning Extended As Cooling Trend Is Pushed Back

LOS ANGELES, CA — Los Angeles baked under another day of triple-digit heat as much as 20 degrees above normal Tuesday. The heatwave is expected to continue one more day before a significant cooldown is expected Thursday, according to the National Weather Service.

An excessive heat warning will remain in place through Thursday. The San Fernando Valley, which saw temperatures of 102 Tuesday, will continue to endure unseasonably warm temperatures as high as 100 degrees on Wednesday, according to forecasters. Downtown Los Angeles and even coastal communities saw highs in the 90s Tuesday, according to the weather service.

The cooldown, which will begin Thursday, is expected to be gradual. In the North Hollywood area, the high is expected to go from about 100 Wednesday to 95 Thursday before settling into the upper 80s by the weekend, according to the National Weather Service.

In the San Fernando Valley, cooling centers include the North Hollywood Amelia Earhart Regional Library at 5211 Tujunga Avenue, and the Studio City Branch Library at 12511 Moorpark Street.

The National Weather Service on Tuesday added the Santa Monica Mountains to its roster of areas under an excessive heat warning through 8 p.m. Wednesday -- up in severity from the heat advisory that had been in place until 8 p.m. Tuesday for that area.

Excessive heat warnings were also extended from Tuesday at 8 p.m. to Wednesday at 8 p.m. for the Santa Clarita, San Fernando and San Gabriel valleys.

The NWS warned of "dangerously hot conditions with temperatures up to 105. Hottest in the San Fernando and Santa Clarita Valleys."

Inland areas such as Beverly Hills, Compton, Lakewood, Norwalk, Culver City and Downey -- where highs of up to 98 degrees are anticipated -- were under an excessive heat warning as well, but only through 8 p.m. Tuesday.

Earlier forecasts had predicted some relief by Wednesday, but now more moderate conditions are expected by Thursday, according to the NWS.

"Persistent high pressure and the associated heat wave will peak (Tuesday) and Wednesday before a weak low to the north brings cooler conditions to the region Thursday," the weather service said.

"Cooler weather should last through the weekend with increasing night to morning low clouds and onshore winds."

The NWS also warned of elevated fire conditions through Wednesday due to the hot and dry weather, with the "potential for large vertical plume growth."

Meanwhile, in Orange County, forecasters issued excessive heat watches through 8 p.m.

"Drink plenty of fluids, stay in an air-conditioned room, stay out of the sun, and check up on relatives and neighbors," the NWS advised. "Young children and pets should never be left unattended in vehicles under any circumstances."
