Red Flag Warning
URGENT - FIRE WEATHER MESSAGE
National Weather Service Los Angeles/Oxnard CA
1005 AM PDT Sat Sep 7 2024
...RED FLAG WARNING IN EFFECT THROUGH THIS EVENING FOR ALL
MOUNTAINS, ANTELOPE VALLEY AND ADJACENT FOOTHILLS, AS WELL AS
SOUTHERN SANTA BARBARA COUNTY FOR EXTREMELY HOT AND DRY
CONDITIONS, LOCALLY GUSTY WINDS AND POTENTIAL DRY LIGHTNING...
.A long duration heat wave will continue away from the immediate coast,
with only minor and slow improvement through Monday. Near record high
temperatures will continue this weekend with highs between 105
and 115 common over the valleys, lower mountains, and deserts, and
95 to 105 over the inland coastal plain. Very warm temperatures
will persist at night across the mountains and foothills.
Locally gusty winds will form as well, strongest over southern
Santa Barbara County with Sundowner gusts between 25 and 40 mph
each night through Monday. There will be increasing instability
today, leading to deep mixing heights up to 18,000 feet, which
will also lead to a high risk for erratic plume-dominated fire
behavior, especially in the mountains, foothills, and deserts.
While standard Red Flag Warning criteria is unlikely, there is a
history of large fires during similar weather conditions. As a
result, Red Flag Warnings will remain in place for all mountain
and foothill areas through this evening, with the areas of
highest concern being those with the stronger winds like southern
Santa Barbara County. There is a threat of thunderstorms this
weekend as mid level monsoonal moisture and instability move into
the region. The best chance of storms will be across the mountains
of Los Angeles and Ventura counties, as well as the Antelope
Valley. Any storms that develop today will have the potential for
dry lightning strikes and strong/erratic downburst winds, with
localized gusts to 50 mph possible this afternoon.

WINDS OVER THE MOUNTAINS AND FOOTHILLS OF SOUTHWEST CALIFORNIA...
* WINDS...West to north winds 10 to 15 mph with gusts up to 30
mph. Gusty and erratic winds possible with any new fires or
thunderstorms.
* RELATIVE HUMIDITY...Minimums 8 to 15 percent. Poor overnight
recoveries of 15 to 30 percent.
* TEMPERATURES...Maximums between 100 and 110 common for lower
elevations, with minimums between 82 and 92. Isolated highs
near 115 possible.
* THUNDERSTORMS...There is an increasing risk for dry lightning
over Los Angeles and Ventura Counties this weekend, which can
start new fires, spread them rapidly with gusty downburst
winds, and provide little if any extinguishing rain.
* IMPACTS...If fire ignition occurs, conditions are favorable
for rapid fire spread and extreme fire behavior which would
threaten life and property.
PRECAUTIONARY/PREPAREDNESS ACTIONS...
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

...AIR QUALITY ALERT FOR ELEVATED OZONE AIR POLLUTION AND ELEVATED
FINE PARTICLE POLLUTION LEVELS DUE TO WILDFIRE SMOKE...
The South Coast AQMD has issued an air quality alert in the South
Coast Air Basi n due to high levels of ozone (smog) and increased
fine particle pollution from wildfire smoke in the region. The air
quality alert for smog is in effect until Monday evening. The air
quality alert is in effect until Saturday afternoon.
High ozone levels are expected to impact most of the South Coast Air
Basin. Smok e is expected to impact the Inland Empire and the San
Bernardino Mountains.
Elevated levels of ozone - the predominant summertime pollutant -
are likely to result in poor air quality in the afternoon and early-
evening hours. Ozone air p ollution can cause respiratory health
problems, including trouble breathing, ast hma attacks, and lung
damage. Children, older adults, and people with asthma or COPD may
be more sensitive to the health effects of ozone.
Air quality can change depending on time of day and weather
conditions. Increase d emissions of chemicals and faster ozone
formation rates due to heat, along wit h low winds and stagnant
weather can cause unusually high and persistent levels of ozone
pollution.
If you smell smoke or see ash due to a wildfire, remain indoors with windows and
doors closed or seek alternative shelter, if feasible. Avoid vigorous physical
activity and run your air conditioner and/or an air purifier. If possible, do no
t use whole house fans or swamp coolers that bring in outside air. Avoid burning
wood in your fireplace or firepit and minimize sources of indoor air pollution
such as candles, incense, pan-frying, and grilling. If you must be outdoors, kee
p the time brief and wear a tightly-fitted N-95 or P-100 respirator to help redu
ce exposure. Limit the use of gasoline powered lawn and garden equipment.
Exposure to particle pollution can cause serious health problems, aggravate lung
disease, cause asthma attacks and acute bronchitis, and increase risk of respir
atory infections. People with heart or lung diseases should follow their doctor`
s advice for dealing with episodes of unhealthy air quality. Additionally, peopl
e with respiratory or heart disease, older adults, and children are particularly
susceptible and should avoid prolonged exposure, strenuous activities or heavy
exertion as conditions dictate.
Levels of particle pollution can vary hour by hour and by location depending on
fire behavior and local weather conditions.
To help minimize ozone air pollution levels:
- Limit the use of gasoline powered lawn and garden equipment until
evening hour
- Conserve electricity and set your air conditioner at a higher
temperature
- Try to delay trips to the gas station and the use of
household chemicals until the evening
Check air quality levels and take appropriate action as needed. When air qualit
y index (AQI) levels are Unhealthy for Sensitive Groups (orange), people with he
art or lung disease, pregnant women, children, and older adults should limit pro
longed or heavy outdoor exertion. When air quality reaches Unhealthy (red) AQI l
evels, everyone may experience adverse health effects and sensitive groups shoul
d avoid prolonged time outdoors. At Very Unhealthy (purple) AQI levels, sensitiv
e groups should avoid all outdoor physical activity and everyone else should avo
id prolonged or heavy outdoor exertion.
