URGENT - FIRE WEATHER MESSAGE
National Weather Service Los Angeles/Oxnard CA
127 PM PDT Thu Oct 19 2017

...Critical Fire Weather Conditions possible Saturday through
Tuesday for portions of Southwest California...

.Gusty northwest to north winds will increase across much
of Southwest California Friday into Friday night following
the passage of an upper level trough. While there will be
elevated fire danger due to these gusty winds, humidities are not
expected to be sufficiently low to reach critical conditions.
However, on Saturday, gusty northerly winds combined with lowering
humidities will bring the potential for critical fire weather
conditions to the mountains.

As the flow turns more northeast Sunday through Tuesday, there
will be a significant warming and drying trend across all of
Southwest California, with the potential for critical fire weather
conditions extending into the valleys. The most critical fire
weather conditions appear to be Monday through Tuesday, when there
will be a combination of Santa Ana winds gusting to between 35
and 50 mph, record breaking triple digit heat, humidities
lowering into the single digits, and very dry fuels. In addition,
very warm and dry conditions during the overnight hours in the
mountains, foothills, and wind prone areas will add to this fire
weather threat during this long duration of dangerous fire weather
conditions. Coastal areas of Los Angeles and Ventura counties
will potentially need to be included in the Watch area for Monday
or Tuesday as we draw closer to the event.
