DUE TO STRONG SANTA ANA WINDS AND LOW HUMIDITIES...

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

.A very strong, widespread, and long-duration Santa Ana wind
event will bring widespread Extremely Critical fire weather
conditions to many areas of Los Angeles and Ventura counties
Wednesday into Thursday. This will be a PARTICULARLY DANGEROUS
SITUATION (PDS) Red Flag Warning event in many areas, with the
combination of strong upper level wind support, tightening
offshore pressure gradients (LAX-Daggett peaking at -7 to -8 mb),
and moderate cold air advection. The strongest winds with this
Santa Ana wind event are expected to be Wednesday morning into
Wednesday night when widespread damaging wind gusts of 60 to
80 mph are likely in the mountains and foothills of Los Angeles
and Ventura Counties (including the Santa Monicas and Santa
Susanas), with isolated gusts of 80 to 100 mph possible in
favored areas of the San Gabriels. Similar winds are expected
once again in the mountains Thursday night. For wind prone
coastal and valley areas of Los Angeles and Ventura counties,
damaging gusts of 50 to 70 mph will be likely (including the
Malibu Coast and Ventura County coastal plain). Due to the strong
upper level wind support, typical wind sheltered areas such as
portions of the LA basin all the way to the coast, Lake Casitas
and Ojai, as well as the Channel Islands and Catalina Island are
expected to see gusty north to northeast winds with associated
Red Flag conditions. Humidity levels are also expected to lower
to between 8 to 15 percent by Wednesday afternoon with these low
humidities likely to linger into Thursday and Friday.

These are Extremely Critical and highly volatile conditions. Any
new fires in the Red Flag Warning area -- and especially the PDS
Red Flag Warning area -- will have rapid fire spread, extreme
fire behavior, and long range spotting.

...RED FLAG WARNING REMAINS IN EFFECT UNTIL 6 PM PST THURSDAY FOR
THE ANTELOPE VALLEY AND FOOTHILLS AND THE SAN GABRIEL VALLEY AS
WELL AS CALABASAS AND AGOURA HILLS DUE TO STRONG SANTA ANA WINDS
AND LOW HUMIDITIES...

* WINDS...Northeast winds will increase to 30 to 45 mph with
  damaging gusts of 50 to 70 mph through tonight. Strongest winds
  expected along the Highway 118/210 corridors in eastern Ventura
  county valleys to western San Fernando valley, with highest
  risk for Simi Valley, Moorpark, Porter Ranch, and San Fernando.
  Offshore winds are expected to be 5 to 10 mph weaker on
  Thursday.

* RELATIVE HUMIDITY...Humidity levels will likely fall to
  between 8 and 15 percent by Wednesday afternoon, and linger
  into Thursday.

* IMPACTS...If fire ignition occurs, conditions are favorable
  for rapid fire spread and extreme fire behavior which would
  threaten life and property. With the threat of even stronger
  Santa Ana winds and drier fuels with the Wednesday/Thursday
  Santa Ana event, there will be an increased risk for long
  range spotting.

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
