  • Fire Weather Watch for Ventura County Coast County, California
  • Fire Weather Watch issued October 20 at 2:02PM PDT until October 24 at 6:00PM PDT by NWS
  • Effective: Sunday, October 22, 2017 at 6 a.m.
  • Expires: Tuesday, October 24, 2017 at 6 p.m.
  • ...Critical Fire Weather Conditions likely Saturday through
    Tuesday for portions of Southwest California due to gusty
    north to northeast winds...low humidities...and hot
    temperatures...
    .Gusty northwest to north winds will continue across much of
    Southwest California this afternoon into tonight following the
    passage of an upper level trough. While there will be elevated
    fire danger due to these strong winds, humidities are not
    expected to be sufficiently low to reach critical conditions.
    However, by early Saturday morning, gusty northerly winds combined
    with lowering humidities will likely bring critical fire weather
    conditions to the mountains...especially across the Santa Ynez
    range and Interstate 5 corridor.
    As the flow turns more northeast Sunday through Tuesday, there
    will be a significant warming and drying trend across all of
    Southwest California, with the potential for critical fire
    weather conditions extending into the valleys and coastal areas
    of Los Angeles and Ventura counties. The most critical fire
    weather conditions are expected Monday through Tuesday, when
    there will be a combination of Santa Ana winds gusting to between
    40 and 50 mph, record breaking triple digit heat, humidities
    lowering into the single digits, and very dry fuels. In addition,
    very warm and dry conditions during the overnight hours in the
    mountains, foothills, and wind prone areas will add to this fire
    weather threat during this long duration of dangerous fire weather
    conditions. If fire ignition occurs, there will be the potential
    for very rapid spread of wildfire with long range spotting and
    extreme fire behavior that could lead to a threat to life and
    property.
    ...FIRE WEATHER WATCH IN EFFECT FROM SUNDAY MORNING THROUGH
    TUESDAY AFTERNOON FOR GUSTY NORTHEAST WINDS AND LOW RELATIVE
    HUMIDITY FOR THE VENTURA COUNTY VALLEYS...SAN FERNANDO VALLEY...
    AND SANTA MONICA MOUNTAINS...

    mph across the western portions of the Santa Monicas and
    eastern foothills of Ventura County.
    * Relative Humidity...Minimum values 10 to 15 percent on Sunday,
    lowering to between 5 and 12 percent Monday through Tuesday.
    Very poor humidity recoveries expected each night in the
    foothills and wind prone areas.
    * Temperatures...Max temperatures 88 to 98 degrees on Sunday,
    rising to between 95 and 105 degrees Monday into Tuesday. Very
    warm overnight low temperatures in the foothills and wind prone
    areas...remaining 75 to 80 degrees in warmest locations.
    * Impacts...If fire ignition occurs, there will be the potential
    for very rapid spread of wildfire with long range spotting and
    extreme fire behavior that could lead to a threat to life and
    property.
