Much of the Bay Area faced 80s or 90s Sunday as hot weather gripped the region.
The high heat prompted the National Weather Service to issue a heat advisory for much of the Bay Area through 9 p.m. Sunday. The sizzling temperatures, coupled with gusty winds, also triggered a red flag warning for the North Bay mountains through Sunday afternoon.
Cities in the East Bay such as Concord and Livermore were slated to reach 99 degrees Sunday, according to the weather service. Santa Rosa and Napa were expected to soar to 96 degrees. In the South Bay, San Jose was expected to bake at 98 degrees while Gilroy was predicted to roast at 100 degrees. San Francisco, which is typically socked in by fog this time of year, was expected to check in at 88 degrees.
Weather officials reminded people to stay hydrated, limit the amount of time they spend outside during the hottest time of the day, and keep an eye on children and pets, making sure not to leave them in vehicles.
While people sought relief from the heat, fire officials were keeping a close eye on mountains across the North Bay as a red flag warning remained in place through Sunday afternoon. Any wildfires that ignite could spread rapidly, the weather service warned.
Spare the Air alerts have been issued for the Bay Area on Sunday and Monday.
"Hot inland temperatures, light winds and motor vehicle exhaust from millions of motor vehicles on Bay Area roads will continue to cause unhealthy ozone accumulation in the region," advised the Bay Area Air Quality Management District, which encouraged the public to avoid driving if possible.
