The Bay Area is experiencing a brief but intense heat wave, with temperatures peaking on Thursday before a rapid cooldown. The National Weather Service has issued heat advisories and fire danger warnings, while coastal flood advisories are also in effect.
- Temperatures could reach 100 degrees in inland areas of Contra Costa and Alameda counties, Santa Clara Valley, and North Bay locations like Napa and Santa Rosa. - A red flag warning for fire danger is in effect through Wednesday night, with gusty winds up to 40 mph in the East Bay Hills and North Bay Interior Mountains.
- Coastal flood advisories begin Wednesday night along the North Bay ocean coast and Thursday along the San Francisco Bayshore, with high tides expected. - By Sunday, temperatures will drop significantly, with places that hit 100 degrees Thursday likely staying below 85 as the marine layer returns.
The rapid cooldown will bring relief, but residents are urged to stay hydrated and cautious during the peak heat on Thursday.
