🚨 HEAT ADVISORY: A Heat Advisory is in effect until 11 PM tonight for much of the Bay Area due to widespread Moderate HeatRisk. Interior East Bay & South Bay advisories extend through Friday. Limit outdoor exertion & check the backseat! 🚗 #CAwx #BayAreaWX
Widespread Moderate HeatRisk is anticipated on Thursday and Friday across a good portion of the Bay Area. Moderate Heatrisk means members of heat-sensitive groups will experience negative heat-related health effects, including heat illnesses. Be sure to drink plenty of water, do not leave children or pets in unattended vehicles. Take frequent breaks in air conditions (if applicable) or shade. Shift activities outdoors to cooler times of day.
