Heat warning for the Bay Area in effect until Wednesday evening – NBC Bay Area

Temperatures in the Bay Area are expected to rise rapidly through late Monday morning and a heat advisory is in effect for the entire region.

“A fall heat wave begins today and will last for several days,” the National Weather Service said in a statement released Monday.

The heat warning goes into effect at 11 a.m. and lasts through Wednesday night, but it could be extended for some parts of the Bay Area.

Interior temperatures are expected to reach low to mid 100s and coastal areas will be in the 80s to mid 90s.

“As offshore winds battle the marine layer, the coast will also feel the heat today,” the weather service said.

A sea breeze is expected to cool the coast somewhat in the late afternoon.

The heatwave is likely to bring red flags as offshore winds are expected to continue from Tuesday night into Wednesday morning.

“This period will bring the peak of fire weather concerns, particularly at higher elevations,” the weather service said.

People and pets should not be left in cars without air conditioning, and outdoor activities should be limited for those sensitive to heat, and people should stay hydrated.
