The NWS warned in the bulletin that there will be “dangerously hot” temperatures with limited overnight cooling. Temperatures are expected to peak in Livermore and Concord, with both cities predicted to hit 103 on Tuesday and one degree higher on Wednesday.
Because of those warmer-than-usual overnight lows, there will be little relief from the heat even when the sun goes down, particularly in interior areas and elevated terrain.
The warning is in effect for areas across the Bay Area and Central Coast that are not directly coastal, according to the release. It was set to expire Friday evening, although temperatures will begin falling Thursday, according to the forecast.
Experts warned that these elevated temperatures raise the possibility of heat related illnesses, especially for people working outdoors. The NWS advised that people drink plenty of fluids, avoid the sun, stay in air conditioning and check in with relatives and neighbors. They also added that children and pets should not be left in cars unattended, as cars can reach lethal temperatures very quickly.
