For the weekend, an Excessive Heat Warning has been issued for inland portions of the Bay Area and Central Coast.
According to the National Weather Service, inland temperatures are expected to range from the 90s to 110. Coastal areas are between the 70s to the 80s.
The heat warning takes effect from Saturday morning to late Sunday.
NWS says the hot conditions around the inland Bay Area and Central Coast could cause “life-threatening impacts or major impacts to commerce or travel.”
The weather service warns that there is a “high to very high risk for much of the population due to long duration heat with little to no overnight relief.”
For inland locations like Concord and Livermore, there is a greater than 70% chance of hitting 100-degree temperatures Saturday.
Heat risk will be greatest between 1 p.m. and 6 p.m. The NWS suggests preparing for the heat and limiting outdoor activities during these hours.
Those without air conditioning are advised to visit stores, malls, libraries, movie theaters, and other cool public locations.
“Stay hydrated and take cooling breaks if you must be outdoors,” the weather service advises.
