.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 east winds 20 to 35 mph with gusts to 50
mph.
* RELATIVE HUMIDITY…Daytime humidities of 10 to 20 percent
common with minimal improvement 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
information.
