URGENT - FIRE WEATHER MESSAGE
National Weather Service Los Angeles/Oxnard CA
952 AM PDT Sun Sep 6 2020

...RED FLAG WARNING IN EFFECT THROUGH 10 PM MONDAY EVENING FOR 
THE SANTA BARBARA COUNTY MOUNTAINS AND SOUTH COAST DUE TO GUSTY 
SUNDOWNER WINDS, LOW RELATIVE HUMIDITY, AND VERY HOT 
TEMPERATURES...

...RED FLAG WARNING IN EFFECT FROM 6 PM THIS EVENING THROUGH 10 
PM MONDAY EVENING FOR THE LOS ANGELES AND VENTURA COUNTY MOUNTAINS
DUE TO GUSTY NORTH WINDS, LOW RELATIVE HUMIDITY, AND VERY HOT 
TEMPERATURES...

.Strong high pressure will continue to bring a dangerous and
record breaking heat wave with low humidities to Southwest 
California through at least Labor Day. Today will be the hottest
day of the current heat wave with ALL-TIME record high
temperatures expected at some locations. The very hot and 
unstable conditions will bring a significant threat of large plume
dominated fires. Gusty Sundowner winds across southern Santa 
Barbara county and gusty northerly winds in the Los Angeles and 
Ventura county mountains (especially near the Interstate 5 
corridor) will likely bring critical fire weather conditions to 
these areas, resulting in the Red Flag Warnings for these areas. 
The critically dry fuels will result in a greater threat of fire 
ignitions as well as rapid fire growth. With an extremely hot air
mass in place, the Sundowner winds will maintain very hot 
temperatures of 100 to 107 degrees with humidities 8 to 15 
percent through much of the night in the foothills and wind 
exposed canyons of the Santa Barbara south coast.

...RED FLAG WARNING REMAINS IN EFFECT UNTIL 10 PM PDT MONDAY FOR
THE SANTA BARBARA COUNTY MOUNTAINS AND SOUTH COAST DUE TO GUSTY
SUNDOWNER WINDS, LOW RELATIVE HUMIDITY, AND VERY HOT
TEMPERATURES...

* Winds...Northwest to north winds 15 to 30 mph with local gusts
  up to 45 mph tonight and Monday night. Strongest winds in the
  Santa Ynez mountains, as well as the foothills and canyons of
  the south coast. Winds will be lighter during the daytime hours
  and become onshore each day across the coast and foothills.

* Relative Humidity...8 to 15 percent in the mountains, 
  foothills, and wind prone coastal areas.

* Temperatures...Record breaking maximum temperatures 95 to 112
  degrees. Hottest temperatures today, especially foothills, lower
  mountains, and windy canyons. Very hot temperatures of 95 to 107
  degrees will linger tonight in the foothills and wind exposed 
  areas during the sundowner wind event.

* Impacts...If fire ignition occurs, conditions will be 
  favorable for rapid fire spread, long range spotting, and 
  extreme fire behavior which would threaten life and property. 
  In addition to the threat of a wind driven fire, there is a 
  significant threat of large plume dominated fires with extreme 
  fire behavior in areas where winds are lighter.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

A Red Flag Warning means that critical fire weather conditions
are either occurring now....or will shortly. A combination of
gusty winds...low relative humidity...very hot temperatures, and
critically dry fuels can contribute to rapid fire spread and
extreme fire behavior. Use extreme caution with potential fire
ignition sources. Prepare now and assemble your emergency kits.
