Red Flag Warning issued July 3 at 8:17PM PDT until July 6 at 9:00PM PDT by NWS San Francisco CA

…CRITICAL FIRE WEATHER CONDITIONS INTO FRIDAY AND THE UPCOMING
WEEKEND…

.Red Flag Warnings currently in effect for high elevations of the
North Bay, East Bay Hills, and the Santa Cruz Mtns and have been
extended through 9 PM Saturday. The Marin and Sonoma Coastal
Ranges will see their Red Flag Warning end at 5 AM Friday. Also,
Red Flag Warnings go into effect at 5 AM Friday through 9 PM
Saturday for the higher terrain of Monterey and San Benito
counties as well as the southern Salinas Valley. While the winds
are marginal, this decision was made due to a combination of
continued very low RH in the teens, very dry fuels, and the 4th of
July holiday. Also, gusts up to 25 mph will be possible across
ridgetops and higher peaks. Fuels continue to cure and will see no
relief through this weekend. In fact, 10 and 100 hour fuels are
near historic levels in the North Bay in regard to the energy
release component going into the weekend. The same fuels in the
Diablo Range and Santa Cruz Mtns aren’t far behind.

strong winds, low relative humidity, and warm temperatures can
contribute to extreme fire behavior.
