Forecasted temperatures approaching 100 degrees in the Bay Area Thursday and Friday prompted the National Weather Service to issue a heat advisory for the region.
The advisory for the Bay Area and Monterey Bay area takes effect about noon Thursday and lasts until Friday evening, but may be extended into Saturday.
Temperatures are expected to be highest Friday, with coastal areas such as San Francisco climbing to the mid- to high 80s and potentially reaching the mid-90s, weather service forecasters said.
Inland areas are expected to get even hotter, with temperatures in cities like Concord, Livermore and San Jose expected to approach 100 degrees Friday afternoon.
Thursday's temperatures are expected to reach the mid-80s in coastal areas and the mid-90s in inland areas. Saturday is expected to see some cooling, with temperatures similar to today.
The hot weather, dry air and light winds could pose a potential fire danger, forecasters said.
