Extreme Temperatures Expected As Another Heat Wave Hits Agoura

LOS ANGELES, CA — Another heat wave will bring triple-digit heat to Los Angeles and warm overnight lows, thanks to a high-pressure system, the National Weather Service warned. It will also bring extreme fire danger.

Parts of the San Fernando Valley will surpass 100 degrees Thursday with the heatwave peaking Saturday, forecasters warned. Agoura Hills is expected to swelter with highs in the upper 90s through the weekend. An excessive heat warning will be in effect for parts of Los Angeles County from 10 a.m. Thursday through 9 p.m. Monday, with the National Weather Service predicting "dangerously hot conditions with temperatures up to 113 expected" in the high desert. Combine with the dry vegetation, the extreme heat will trigger elevated fire danger, the NWS warned.

“Vegetation is very dry on the hillsides because we’ve had two very dry years in a row,” said meteorologist David Sweet with the National Weather Service in Oxnard told the Los Angeles Times, “and we’re also looking at 111 degrees. Any time you have hot temperatures, that’s also a contributing factor.”

Forecasters said temperatures won't drop dramatically overnight in the area, with lows expected in the mid-70s to mid-80s.

"High pressure will continue to build over the region into the weekend, leading to warming temperatures each day mainly away from the coast," according to the NWS. "The warmest days will likely be Friday through Sunday when excessive heat will be likely for interior areas.

"Low clouds and fog will be confined to the coastal plain and possibly lower coastal valleys during the overnight and morning hours."

Forecasters said the excessive heat warning could potentially be extended to the Santa Clarita Valley on Friday and beyond, depending on how the high-pressure system unfolds. A continuing onshore flow will keep temperatures cooler along the coast.

While the weather is expected to be hot, forecasters said temperatures will likely remain just shy of daily-record levels, which are in the 110- 115 range, and "certainly short of all-time records which are in the 113-117 range."

The high-pressure system is expected to weaken early next week, but it will still be warmer than usual. Triple-digit temperatures are expected throughout next week in the Antelope Valley.

As with other heat events, the NWS advised residents in the Antelope Valley to stay hydrated, avoid the sun when possible and check up on relatives and neighbors who might be susceptible to heat illness.

"Take extra precautions if you work or spend time outside," forecasters advised. "When possible reschedule strenuous activities to early morning or evening. Know the signs and symptoms of heat exhaustion and heatstroke. Wear lightweight and loose-fitting clothing when possible."

The Los Angeles County Department of Public Health issued a heat alert in response to forecasted elevated temperatures. The alert will be in effect from Friday through Sunday in the western San Fernando Valley, and from Saturday through Sunday in the San Gabriel Valley and the eastern San Fernando Valley.

County officials said residents without air conditioning at home can take advantage of cooling centers, with information on locations available at https://ready.lacounty.gov/hea... or by calling 211.
