Heat Wave To Bake Los Angeles County

LOS ANGELES, CA — Wide swaths of Southern California will bake in triple-digit heat as a heat wave settles over the region, lasting into the work week.

Temperatures are expected to soar above 100 degrees Sunday, Monday and Tuesday, creating life-threatening conditions for vulnerable people in some areas. The National Weathers Service issued heat advisories across the hottest parts of the Southland.

The advisories are in effect from 10 a.m. Sunday to 8 p.m. Monday in the mountains and the San Fernando, San Gabriel and Santa Clarita valleys. As hundreds are expected to gather in Downtown Los Angeles for abortion demonstrations Sunday, they'll face temperatures in the low 90s, according to Accuweather. On Monday, the Downtown high is expected to reach 94 degrees.

"Warm temperatures can quickly rise to dangerous levels — especially in the summer and in parked cars. Stay #WeatherReady and don’t underestimate the heat," the National Weather Service's Los Angeles office tweeted. "Children, the elderly, and those with chronic illness are especially vulnerable to heat exposure."

In the San Fernando Valley, Saturday's high was 97 in Calabasas, where temperatures of 99 degrees on Sunday and 100 on Monday were expected. In Woodland Hills, a high of 99 on Saturday was expected to rise to 100 on Sunday and Monday.

In the Antelope Valley, Lancaster was expected to reach 103 on Sunday, Monday and Tuesday, forecasters said.

Pasadena had a high of 94 on Saturday, but it will rise to 95 on Sunday and 97 on Monday.

In inland Orange County, highs were expected to linger in the upper 80s and lower 90s for the next few days.

The very warm and dry conditions will produce elevated fire weather conditions through Tuesday with brief critical conditions in the windiest areas, according to the NWS.

Temperatures are expected to drop to less dangerous levels beginning Wednesday and stay relatively mild heading into the weekend.

As usual during heat waves, forecasters urged people to drink plenty of fluids, seek out air-conditioned spaces and check in on vulnerable relatives and neighbors.

"Extreme heat will significantly increase the potential for heat related illnesses, particularly for those working or participating in outdoor activities," according to the NWS.

"Young children and pets should never be left unattended in vehicles under any circumstances. This is especially true during warm or hot weather when car interiors can reach lethal temperatures in a matter of minutes."
