CONDITIONS.

PM WEDNESDAY WITH GUSTS DIMINISHING THROUGH THE EVENING…
.Strong and gusty offshore winds, critical relative humidity, and
dry fuels continue across much of the region. North to
northeasterly wind gusts will average between 25 and 40 mph,
particularly across the higher terrain of the Santa Cruz
Mountains, East Bay Hills, North Bay Mountains, as well as
interior portions of Napa and Sonoma counties. Wind gusts between
30 to 40 mph with occasional gusts greater than 55 mph will
continue across the North Bay interior mountains through
Wednesday evening. Afternoon humidity values will range between
the single digits and 25 percent. Overnight humidity recovery will
be poor between 20 and 45 percent. Fire crews and residents are
urged to remain abreast of the weather forecast through Thursday
morning.
* AFFECTED AREA…Fire Weather Zone 517 Santa Lucia Mountains
and Los Padres National Forest and Fire Weather Zone 518
Mountains of San Benito County And Interior Monterey County
including Pinnacles National Park.
* TIMING…11 AM Tuesday until 5 PM Wednesday.
* WINDS…Southeast 5 to 10 mph with gusts up to 25 mph.
* RELATIVE HUMIDITY…As low as 17 percent.
* LIGHTNING…None anticipated.
* IMPACTS…Despite recent rainfall, a long duration offshore flow
event is anticipated. This will result in the rapid curing of
fuels. The combination of breezy winds and low humidity will
cause fire to rapidly grow in size and intensity. Wind speeds
will diminish by this evening but critically dry conditions will
persist through Thursday. Outdoor burning is not recommended
and may be prohibited in some areas.
A Red Flag Warning means that critical fire weather conditions
are either occurring now…or will shortly. A combination of
strong winds…and low relative humidity can contribute to
extreme fire behavior.
