Triple-digit temperatures and humidity was expected in parts of L.A. County Sunday, before the hot weather gave way to rain and potentially dangerous lightning in the coming days.
The valleys would likely reach triple digits, with other parts of Los Angeles nearly reaching that and getting some humidity, according to the National Weather Service.
The weather could pose a danger to those working outside or those without an air conditioner.
But by the following day, L.A. County could see rain and thunderstorms, along with “dangerous lightning” on Monday and Tuesday, the weather service warned.
The storm was expected a week after Southern California got record rainfall, leading to the evacuation of about 100 West Hollywood residents, thousands of Southern California Edison customers to lose power and dozens of crashes.
More than two inches of rain was recorded in downtown L.A. last Tuesday, making it the third-wettest September storm since the 1870s, climatologist Bill Patzert with the Jet Propulsion Laboratory told the Los Angeles Times.
