The National Weather Service has issued red flag warnings for parts of the Bay Area, including Santa Clara County, in response to thunderstorms. A red flag warning indicates that critical fire weather conditions are happening or are imminent in the area. The warning is in effect until 5 p.m. Saturday (Sept. 10).
The warnings were issued in response to thunderstorms that are moving into the Bay Area from the northeast, National Weather Service spokeswoman Diana Henderson said.
Henderson said dry lightning could ignite wildfires and residents are urged to be watchful and are reminded not to set campfires and be cautious when discarding cigarette butts.
"It's volatile out there," she said.
