...ELEVATED FIRE WEATHER CONCERNS FOR THE BAY AREA AND CENTRAL
COAST THURSDAY INTO THE WEEKEND AS STRONG OFFSHORE WINDS ARE
EXPECTED TO DEVELOP...
.Gusty north-northeast winds are expected to develop as a
potential "inside slider" system moves into the Great Basin this
weekend. Humidities will still be on the higher end at the start
of the event on Thursday, but are expected to quickly dry out
becoming critically dry Friday and Saturday, as low as 15%.
However, impacts are expected as soon as Thursday afternoon with
winds increasing across the region. Most areas will be affected
to some degree, with likely exceptions being the immediate Big
Sur coast, Monterey Bay coast, and the Marin/Sonoma coast. Winds
largely on the order of 20-30 mph can be expected with gusts to
40 mph...isolated gusts to 50 mph across the highest terrain and
ridgetops.

* WINDS...North 10 to 20 mph with gusts up to 40 mph.
* RELATIVE HUMIDITY...As low as 15 percent.
* LIGHTNING...None.
* IMPACTS...The combination of gusty winds and low humidity can
cause fire to rapidly grow in size and intensity. Outdoor
burning is not recommended. Despite relative humidity being on
the higher end of critical fire weather criteria, we are
expecting a widespread and prolonged offshore wind event which
will likely dry fuels out very quickly given their volatility
over the past several weeks.
