Red Flag Warning


URGENT - FIRE WEATHER MESSAGE
National Weather Service San Francisco CA
550 AM PDT Sat May 8 2021

...Red Flag Warning for the North and East Bay Hills, as well as
the East Bay Interior Valleys, through 6 am Monday for offshore
winds and low humidity...

.A moderate early season offshore wind event will continue through
the weekend, mainly in the North and East Bay Hills. This will
occur as fuels are near record dry levels after a very dry winter.
The initial burst of dry offshore winds developed at the higher
elevations of the North and East Bay on Friday night and are
expected to develop locally into the East Bay Valleys by late
Saturday morning. These winds will usher in much drier air along
with wind gusts in excess of 50 mph above 2000 feet. Inland
temperatures will warm well into the 80s on Saturday while
humidity values lowering into the teens, and locally as low as the
single digits. This pattern will help to rapidly dry out the fine
fuels through the weekend. There may be some moderate humidity
recovery Saturday night, but warm and dry weather will persist
into Sunday with continued dry northerly winds that will allow
for rapid fire spread on any new ignitions, especially in the
grass and dry brush.

  afternoon with only moderate overnight recovery.

* TEMPERATURES...Highs into the 80s and lower 90s Saturday.
  Slightly cooler on Sunday, but still warm inland.

* IMPACTS...New ignitions will experience rapid fire growth.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

A Red Flag Warning means that critical fire weather conditions
are either occurring now...or will shortly. A combination of
strong winds...low relative humidity...and warm temperatures can
contribute to extreme fire behavior.
