Blistering summerlike temps are coming to Los Angeles

“If you must be outdoors, drink a lot of water,” said Richard Thompson, a meteorologist with the weather service's office for Los Angeles. “There’s definitely the potential for records being set."

The hottest day around Los Angeles will be Thursday, with the mercury possibly hitting 95 degrees (35 Celsius) in the San Fernando Valley. Temperatures are typically around 70 (21 Celsius), said Thompson.

Workers at outdoor construction sites will have plenty of drinking water and electrolyte packets available to stay hydrated. They're instructed to take frequent breaks, said Junior Pineda, a representative with a local unit of the International Union of Bricklayers & Allied Craftworkers.

“And there’s always shade structures, if guys start feeling a little light-headed and need to take a few minutes,” he said.

Los Angeles city and county officials planned to open cooling centers for residents without air conditioning.

Zack Marquez, who uses a wheelchair, was taking care of errands Wednesday before it got too hot in LA's Koreatown neighborhood.

“Gotta stay hydrated and stay in the shade,” he said.

A sea breeze on Friday should cool down the coast somewhat, but inland areas will still swelter, forecasters said.

Celebrities are streaming into Los Angeles ahead of Sunday’s Oscars, with a bevy of events this week taking advantage of the concentration of stars. But the worst of the weather should be over in time for the ceremony.

The rest of the state will also see hotter-than-normal weather starting next week. Temperatures could top 90 (32 Celsius) on Monday around San Francisco and in the Sacramento area.
