Fire Danger: Sonoma County Hills Under Red Flag Warning

SONOMA COUNTY, CA — Sonoma County is among the Bay Area locations under the first red flag warning of the fire season.

The National Weather Service issued the warning, which will be in place from 11 p.m. Friday until 6 a.m. Monday. The North and East Bay hills are included in the red flag warning, as are the East Bay valleys and the eastern half of Santa Clara County.

Any fire will spread rapidly, especially in grass and brush, the weather service said.

The warning was issued after officials determined that offshore wind would develop this weekend, with fuels at near-record dry levels following a dry winter, the weather service said. The winds are forecast to hit the Napa County hills first, then spread to the East Bay overnight and early Saturday.

Warm and dry conditions are forecast Saturday and Sunday. The pattern will continue to dry out grasses, the weather service said.
