A heatwave that kicked off after Labor Day in the western U.S. will keep bringing dangerous temperatures to millions of people this weekend, and some of the worst heat is settling on Southern California.
On Friday, Downtown Los Angeles reached a heat index of 112 degrees, the third time the area has reached that level since 1877, the local NWS office said on social media . An excessive heat warning is still in effect in Los Angeles County.
In San Diego and Orange counties, coastal towns will reach around 90 degrees while some inland suburbs should hit near 110 degrees. Palm Springs will be a sweltering 112 degrees Saturday.
Meanwhile in Oregon and Washington, hot temperatures have also prompted red flag warnings for wildfire risk in the Cascade Mountains, the NWS Portland office said.
Heat can cause serious illness or death, the Centers for Disease Control and Prevention says . People are at greater risk if they are elderly, younger, work outside, have underlying health conditions or don’t have air conditioning or are homeless.
