…FIRE WEATHER WATCH IN EFFECT FROM LATE TUESDAY MORNING THROUGH
FRIDAY AFTERNOON FOR POTENTIAL STRONG/DAMAGING NORTH TO NORTHEAST
WINDS AND LOW RELATIVE HUMIDITY FOR MUCH OF LOS ANGELES AND
VENTURA COUNTIES…
…FIRE WEATHER WATCH IN EFFECT FROM TUESDAY NIGHT INTO WEDNESDAY
FOR LA COUNTY COAST EXTENDING INTO PALOS VERDES, AND CATALINA
ISLAND DUE TO MODERATE TO STRONG NORTH TO NORTHEAST WINDS AND LOW
RELATIVE HUMIDITY…
.While there is still some uncertainty in next week’s wind event,
the most likely outcome is for strong/damaging north to northeast
winds with an extended period of Red Flag conditions. While the
longer duration of strong winds is expected to be focused across
Los Angeles and Ventura counties, there is a 20-30 percent chance
of shorter duration Red Flag conditions across portions of Santa
Barbara and San Luis Obispo counties. Due to the potential for
damaging winds, there will be an increased risk for downed trees
and powerlines, as well as power outages. There is also the
potential for moderate to strong north to northeast winds for the
LA county coast (especially Hollywood Hills, Beverly Hills, and
Sepulveda Pass) extending into Palos Verdes and Catalina Island
Tuesday night into Wednesday, resulting in the issuance of a Fire
Weather Watch for these areas.
The National Weather Service in Los Angeles/Oxnard has issued a
Fire Weather Watch for moderate to strong north to northeast winds
and low relative humidity, which is in effect from Tuesday evening
through Wednesday afternoon.
* WINDS…Most Likely Outcome-Moderate to strong north to
northeast winds Tuesday night into Wednesday with sustained
winds of 20 to 35 mph and potential damaging wind gusts of 40 to
60 mph. Strongest winds likely in the Hollywood Hills, Beverly
Hills, Sepulveda Pass, Palos Verdes extending into Catalina
Island.
* RELATIVE HUMIDITY…Most Likely Outcome-Humidities likely
falling to between 20 and 30 percent in many areas by Tuesday
afternoon, then widespread 15 percent or less potentially
Tuesday night into Wednesday. There is also a chance of
localized single digit humidities on Wednesday.
* IMPACTS…If fire ignition occurs, conditions are favorable
for rapid fire spread and extreme fire behavior, including
long range spotting, which would threaten life and property.
There will be the potential for downed trees and powerlines,
as well as power outages.

strong/damaging north to northeast wind event (70% chance),
