valleys, and the hills above Camarillo.

The National Weather Service in Los Angeles/Oxnard has issued a
Red Flag Warning for wind and low relative humidity, which is in
effect from 10 AM Monday to 6 PM PST Wednesday. The Fire Weather

* WINDS...Santa Ana winds expected to increase sharply late Monday
morning into afternoon, then peak Monday night into Tuesday.
when speeds of 25 to 40 mph with gusts of 35 to 55 mph will
likely be common. Isolated gusts as high as 55 to 70 mph will be
likely during the peak of the event in the windiest locations,
such as the western San Gabriels, Santa Susanas, western Santa
Monicas, Ventura county valleys, and hills above Camarillo.
Offshore winds are expected to diminish some on Wednesday, with
gusts mostly in the 20 to 40 mph range.
* RELATIVE HUMIDITY...Humidities are expected to lower to around
15 percent in many areas by Monday afternoon, with widespread
humidities of 5 to 10 percent likely from Monday night or
Tuesday, and persisting into Wednesday, with isolated readings
as low as 2 percent likely.
* IMPACTS...If fire ignition occurs, conditions are favorable for
very rapid fire spread, extreme fire behavior, and long range
spotting, which would threaten life and property. There is also
the risk of locally damaging winds including trees and power
lines.
