Rising temperatures prompt Bay Area heat advisory – NBC Bay Area

A heat advisory for much of the Bay Area will go into effect Wednesday morning and last through Thursday night, as temperatures are expected to rise between 90 and 100 degrees Celsius in most places, according to the National Weather Service.

Even San Francisco, usually exempt from such heat alerts, is among the regions under a heat advisory, with temperatures expected to approach the 80s, the weather service says.

Interior temperatures in the East Bay, South Bay and North Bay will climb into the lower 90s and 100s Wednesday and Thursday, the weather service says.

Meteorologist Kari Hall follows warm temperatures and unhealthy air quality with a weekend chill in the Microclimate Forecast.

A heat advisory means there is a moderate risk of heat that could affect those sensitive to heat, especially people without access to cooling or adequate hydration, the weather service says.

Weather officials are advising people in affected areas to drink plenty of fluids, stay in an air-conditioned structure and stay out of the sun if possible. Small children and pets should never be left unattended in vehicles under any circumstances.

The heat advisory officially runs from 11:00 a.m. Wednesday until 11:00 p.m. Thursday.
