***THIS IS A PARTICULARLY DANGEROUS SITUATION (PDS) FOR MANY
  AREAS OF LOS ANGELES AND VENTURA COUNTIES ***

A strong, widespread, and long duration Santa Ana event will
bring widespread critical to extremely critical fire weather
conditions to many areas of Los Angeles and Ventura counties
through Wednesday. This will be a PARTICULAR DANGEROUS
SITUATION (PDS) Red Flag Warning event in many areas, with the
combination of a strong offshore pressure gradient (LAX-Daggett
peaking at -8 to -9 mb), strong cold air advection, and moderate
upper level wind support.

As surface high pressure builds into the Great Basin, Santa Ana
winds are expected to increase through the afternoon,
then peak tonight into Tuesday. A marine layer cloud presence
this morning may delay the onset of offshore winds across
portions of the coast and coastal valleys by a few hours from
what was expected yesterday. Offshore winds are expected to
diminish some by Wednesday, but very dir will persist. With the
strong likelihood of widespread single digit humidities with this
event, there is high confidence for a long duration Red Flag
event. In addition, there is high confidence of PDS Red Flag
Warning conditions late this evening through Tuesday, as
damaging wind gusts of 60 to 80 mph will likely overlap with
single digit humidities across many of the windier mountain and
foothill areas, and with gusts of 40 to 65 mph across most wind
prone coastal and valley areas of Los Angeles and Ventura
counties. With the threat of damaging wind gusts in these windier
corridors, there will be an increased risk for downed trees and
powerlines, along with power outages. The hardest hit areas will
likely be the San Gabriels, Santa Susanas, western Santa Monicas
into Malibu, Ventura county valleys (especially Simi Valley and
Moorpark), western San Fernando Valley (especially Highway
118/210 corridors from Porter Ranch to San Fernando), and the
hills above Camarillo into east Ventura. Due to the expected long
duration of dangerous fire weather conditions and critically dry
fuels, there is an increased risk for any new ignitions to
have very rapid fire spread and extreme fire behavior (including
long range spotting). As a result, there is the increasing threat
for fire weather conditions to rival other historical fires in
recent times including the Mountain and Thomas Fires. Dry
offshore conditions will likely persist into Thursday morning, with
a return of onshore flow and some humidity recovery in the afternoon.

...PARTICULARLY DANGEROUS SITUATION (PDS) RED FLAG WARNING IN EFFECT
FROM 8 PM TONIGHT UNTIL 2 PM TUESDAY DUE TO DAMAGING SANTA ANA WINDS
AND VERY LOW HUMIDITIES FOR THE FOLLOWING AREAS: VENTURA COASTAL PLAIN
(ESPECIALLY FOOTHILLS)/ MALIBU COAST -- AND RED FLAG WARNINGS IN
EFFECT FOR ALL OTHER TIMES UNTIL 2 PM WEDNESDAY IN THESE SAME AREAS...

* WINDS...Santa Ana winds expected to increase sharply by mid to
  late this afternoon, then peak later this evening through
  Tuesday, when speeds of 25 to 40 mph with gusts of 40 to 55
  mph will likely be common. Isolated damaging gusts of 55 to 65
  mph will be likely in the hills above Camarillo and Somis
  extending into east Ventura, as well as Point Mugu and Malibu.

* RELATIVE HUMIDITY...Humidities are expected to lower to around
  15 percent in many areas by late this afternoon or evening,
  with widespread humidities of 5 to 10 percent likely from late
  this evening into Tuesday, and persisting into Wednesday, with
  isolated readings as low as 2 percent likely.

* IMPACTS...If fire ignition occurs, conditions are favorable
  for large fires with very rapid fire spread, extreme fire
  behavior, and long range spotting, which would threaten life
  and property. There is also the risk of damaging winds
  including trees and power lines, as well as power outages.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

A Red Flag Warning means that critical fire weather conditions
are either occurring now, or will shortly. Use extreme caution
with anything that can spark a wildfire. Residents near wildland
interfaces should be prepared to evacuate if a wildfire breaks
out. See readyforwildfire.org and wildfirerisk.org for
information.
