As the San Francisco Bay Area enters the seventh day of a historic heat wave, forecasters are warning people to drink plenty of water and stay inside if possible due to persisting “dangerously hot” conditions.

“All of the heat warnings and advisories — they’ve all been extended,” NWS meteorologist Nicole Sarment said. “We’ve got a tiny disturbance (Friday), and the main threat from that will be an increase in winds, and there’s some degree of moisture. But this isn’t over yet.”
