Bay Area heat wave could be 'deadly, historic' as parts of region face extreme weather next few days

Parts of the Bay Area will be experiencing triple digit heat for several days this week beginning on Tuesday.

On Tuesday afternoon, the National Weather Service said the Bay Area is headed into "an exceptionally dangerous situation" with the triple-digit heat wave.

"An exceptionally dangerous situation is underway as we enter a potentially deadly, historic, and prolonged heat event. Protect yourself during excessive heat and stay," the NWS tweeted on X .

Because of the heat, the Bay Area Air Quality Management District on Tuesday morning issued a Spare the Air alert for both Tuesday and Wednesday .

"Anytime we have very high temperatures, combined with sunlight and vehicle exhaust from cars and trucks on our roads, those are the perfect conditions for smog to form," Erin DeMerritt, a spokesperson for the Bay Area Air Quality Management District said. "One of the best ways that Bay Area residents can limit air pollution all year round and especially in the summertime, is to limit driving to reduce smog."

"It's summertime they're on break, they're at home, they love the water, every parent knows they love to play in water and with it being so warm, it would be the perfect day for this," Omar Mojaddidy, a Fremont resident said. "We're planning on letting them swim for a few hours and get home before noon to 1 o'clock before it starts to really hit."

Doctors are warning people to be careful during this heat wave.
