The National Weather Service has issued a red flag warning for parts of the San Francisco and Monterey bay areas and the Central Coast due to high fire danger.
The red flag warning will be in effect from 5 p.m. Sunday to 5 p.m. Monday in the North Bay mountains, the East Bay hills, the Diablo Range and the Santa Cruz Mountains.
An extended red flag warning between 11 a.m. Sunday and 5 p.m. Monday will be in effect for the Santa Lucia Mountains and mountain ranges in San Benito County.
Meteorologists said Saturday that there is a slight chance for thunderstorms in the region, and that cloud-to-ground lightning may spark new wildfires.
In addition to extreme temperature conditions, the forecast also calls for gusty outflow winds and increased risk of new wildfire starts and rapid spread.
