San Franciscans, prepare to crank up the fans and slather the sunscreen because we're in for a scorcher. According to the National Weather Service, the Bay Area is staring down the barrel of an Excessive Heat Warning starting 11 AM Tuesday through 8 PM Saturday, with sizzling temperatures hitting the upper 90s to 110° range.

It's not just the heat that will be oppressive: fire danger is also ramped up quite considerably. To no one's surprise, Red Flag Warnings are in place for the North Bay Interior Mountains, Marin, Sonoma Coastal Ranges, and the East Bay Hills. 

While those of us closer to the water might enjoy a wee reprieve with cooler temperatures and that onshore flow, it won't provide much comfort for those in higher elevations and away from the immediate coast. Minimal overnight cooling is expected. We're talking overnight temperatures stubbornly sticking like bubblegum in the upper 60s to mid-70s.

The National Weather Service is also dishing out some grade-A common sense, like advising to avoid outdoor activities between 10 AM and 7 PM and suggesting that you "remain in air conditioning if you have that available to you in your residence". And look, if you can't beat the heat, there’s no shame in staking out a spot at the local mall or movie theater. "If you cannot access air conditioned environments, must be outside, work outdoors, or otherwise, there are other precautionary measures you can take to keep yourself and your loved ones safe (including pets!)", warns the NWS advisory.

Lastly, let's not forget about our furry friends. Ensure they have shade and plenty of water—and maybe even treat them to a refreshing spray-down. 

Coastal waters are expected to face "fresh to strong northwesterly breezes" with "gale force to near gale force gusts become more widespread over the coastal waters as high pressure builds", according to the National Weather Service.
