.A long duration Red Flag Warning remains in effect through much
of Los Angeles and Ventura counties through Wednesday, expanding
into the mountains of San Luis Obispo and Santa Barbara counties
by Monday night. THERE WILL LIKELY BE DAMAGING WINDS GUSTING BETWEEN
55 AND 70 MPH ACROSS PORTIONS OF THE RED FLAG WARNING AREA FROM
EARLY TUESDAY MORNING THROUGH WEDNESDAY MORNING, LEADING TO THE
PDS RED FLAG WARNING UPGRADE. AREAS IN THE RED FLAG WARNING
(ESPECIALLY DURING THE PDS TIME FRAME) WILL HAVE A HIGH RISK FOR
LARGE FIRES WITH VERY RAPID FIRE SPREAD, EXTREME FIRE BEHAVIOR, AND
LONG RANGE SPOTTING. WHILE DANGEROUS PDS RED FLAG FIRE WEATHER
CONDITIONS ARE LIKELY WITH THIS EVENT EARLY TUESDAY MORNING INTO
WEDNESDAY MORNING, THIS WIND EVENT IS NOT EXPECTED TO BE AS STRONG
AND DESTRUCTIVE AS LAST WEEK’S WINDSTORM. Due to the more easterly
component of the wind, much of Ventura County will likely have
stronger winds than the offshore wind events this past week.
* WINDS…Periods of northeast to east winds 25 to 35 mph with
gusts to 55 mph on Monday, increasing to 25 to 40 mph with
damaging gusts 60 to 70 mph Tuesday into Wednesday morning.
* RELATIVE HUMIDITY…Daytime humidities of 8 to 20 percent
common, driest Tuesday into Wednesday. Minimal humidity
recovery expected at night.
* IMPACTS…If fire ignition occurs, conditions are favorable
for very rapid fire spread and extreme fire behavior,
including long range spotting, which would threaten life and
property.
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
