Excessive heat warning extends into weekend as late heat wave scorches Bay Area
An excessive heat warning has been extended for much of the Bay Area into the weekend, as a late season heat wave continues to bring record-breaking temperatures to the region.
The National Weather Service announced Thursday afternoon that the warning remains in effect for the North Bay interior and coastal ranges, the entire East Bay and South Bay, eastern San Mateo County and the Santa Cruz Mountains, along with interior Monterey County, the southern Salinas Valley and San Benito County until 11 p.m. Saturday.
Meanwhile, a heat advisory remains in effect for coastal regions, including San Francisco, along with the North Bay valleys and northern Salinas Valley, also until 11 p.m. Saturday.
"Hot and dry conditions continue with dangerous heat and potentially critical fire weather conditions for the remainder of the work week. The heatwave did peak the last couple of days, but impacts from Moderate to Extreme Heat Risk at times, will be felt into the weekend," said a Weather Service statement on Thursday.
