Fall is currently on hold in the Bay Area as a summer-like heat wave delivers triple-digit temperatures to parts of the region. Much of the Bay Area is now under an excessive heat warning through Wednesday night, the National Weather Service announced Monday afternoon. The warning applies to the following areas: North Bay interior and coastal ranges, San Francisco Bay shoreline, interior East Bay, Santa Clara County, and the Santa Cruz Mountains, according to the weather service. Inland locations could see temperatures peaking as high as 108 degrees, the weather service said. Areas along the coast, which are under a heat advisory through Wednesday night as well, may have to sweat out temperatures in the mid-90s. The weather service reminds the public to never leave people or pets in vehicles, to limit outdoor activities during the hottest parts of the day, and to stay hydrated and take cooling breaks throughout the duration of the fall heat spell. bay area weather 10 mins ago Forecast: Unusual October heat PG&E 7 hours ago PG&E power shutoffs planned in North Bay, Northern California This story uses functionality that may not work in our app. Click here to open the story in your web browser.
