Dangerously hot conditions hit states up and down the West Coast over the weekend, owing to a persistent heat wave stretching from the Pacific Northwest to California and the desert Southwest.

Parts of California, Oregon and Washington state will experience extreme heat at least through Tuesday, forecasters said.

More than 30 million Americans are on alert for scorching heat with triple-digit temperatures breaking records. Plus, evacuations grew in California’s wine country as a large wildfire grew overnight.

Southern California should prepare for 'dangerously hot' temperatures through Saturday, but elevated heat will persist into early next week.

Multiple small fires were reported in the Angeles National Forest on Saturday morning due to lightning strikes.

The hottest days of the week are about to blast Southern California on Thursday and Friday, bringing a chance of record temperatures. KTLA's Ellina Abovian reports on Aug. 22, 2025. Details:
