* WHEN...Until 11 PM PDT Wednesday.
* IMPACTS...Most individuals will be at risk for heat-related
illnesses without effective cooling or adequate hydration,
especially with prolonged outdoor exposure. Without effective
cooling and/or adequate hydration, heat-related illnesses
including heat stroke will be a risk to everyone. Overnight
lows will warm as well leading to poor relief from the heat
specifically in elevated terrain and interior areas.
* ADDITIONAL DETAILS...An exceptionally dangerous situation is
expected to unfold during this potentially historic and deadly
heat event. Several days of temperatures well above normal
will lead to compounding effects among people and
infrastructure, with the possibility of numerous heat related
fatalities. It cannot be stressed enough that while one day at
these temperatures may be manageable for some, an event of
this scale, magnitude, and longevity will likely rival
anything we`ve seen in the last 18 years. Heat is the number
one weather related killer in the United States. By this
weekend, it is VERY LIKELY that we add to that statistic if
preparations are not taken seriously.
PRECAUTIONARY/PREPAREDNESS ACTIONS...
Drink plenty of fluids, stay cool, stay out of the sun, and check
up on relatives and neighbors.
Beat the heat and check the backseat! Do not leave young children
and pets in unattended vehicles. Car interiors will reach lethal
temperatures in a matter of minutes.
Take extra precautions when outside. Wear lightweight and loose
fitting clothing. Try to limit strenuous activities to the early
morning or evening. Take action when you see symptoms of heat
exhaustion and/or heat stroke.
To reduce risk during outdoor work, the Occupational Safety and
Health Administration recommends scheduling frequent rest breaks
in shaded or air conditioned environments. Anyone overcome by
heat should be moved to a cool and shaded location. Heat stroke

Red Flag Warning
URGENT - FIRE WEATHER MESSAGE
National Weather Service San Francisco CA
817 PM PDT Wed Jul 3 2024
...CRITICAL FIRE WEATHER CONDITIONS INTO FRIDAY AND THE UPCOMING
WEEKEND...
.Red Flag Warnings currently in effect for high elevations of the
North Bay, East Bay Hills, and the Santa Cruz Mtns and have been
extended through 9 PM Saturday. The Marin and Sonoma Coastal
Ranges will see their Red Flag Warning end at 5 AM Friday. Also,
Red Flag Warnings go into effect at 5 AM Friday through 9 PM
Saturday for the higher terrain of Monterey and San Benito
counties as well as the southern Salinas Valley. While the winds
are marginal, this decision was made due to a combination of
continued very low RH in the teens, very dry fuels, and the 4th of
July holiday. Also, gusts up to 25 mph will be possible across
ridgetops and higher peaks. Fuels continue to cure and will see no
relief through this weekend. In fact, 10 and 100 hour fuels are
near historic levels in the North Bay in regard to the energy
release component going into the weekend. The same fuels in the
Diablo Range and Santa Cruz Mtns aren`t far behind.

and Northern Salinas Valley, Hollister Valley, and Carmel
Valley.
* WHEN...Until 11 PM PDT Wednesday.
* IMPACTS...Those sensitive to heat, such as the homeless,
elderly, children, and pets will be at risk for heat-related
illnesses. Those without effective cooling and/or adequate
hydration will be at the greatest risk.
* ADDITIONAL DETAILS...An exceptionally dangerous situation is
expected to unfold over the next week as we enter a
potentially historic and deadly heat event for inland areas.
Several days of temperatures well above normal will lead to
compounding effects among people and infrastructure, with the
possibility of numerous heat related fatalities. It cannot be
stressed enough that while one day at these temperatures may
be manageable for some, an event of this scale, magnitude, and
longevity will likely rival anything we`ve seen in the last 18
years. Heat is the number one weather related killer in the
United States. By this weekend, it is VERY LIKELY that we add
to that statistic if preparations are not taken seriously.
PRECAUTIONARY/PREPAREDNESS ACTIONS...
Drink plenty of fluids, stay cool, stay out of the sun, and check
up on relatives and neighbors.
Beat the heat and check the backseat! Do not leave young children
and pets in unattended vehicles. Car interiors will reach lethal
temperatures in a matter of minutes.
Take extra precautions when outside. Wear lightweight and loose
fitting clothing. Try to limit strenuous activities to the early
morning or evening. Take action when you see symptoms of heat
exhaustion and/or heat stroke.

...AIR QUALITY ALERT IN EFFECT FOR ELEVATED OZONE FROM 11 AM
WEDNESDAY TO 7 PM PDT SATURDAY...
The South Coast Air Quality Management District has issued an Air
Quality Alert due to elevated ozone air pollution. This Air Quality
Alert is in effect from 11 AM Wednesday to 7 PM PDT Saturday.
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 pollution can cause respiratory health
problems, including trouble breathing, asthma 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. Increased emissions of chemicals and faster ozone
formation rates due to heat, along with low winds and stagnant
weather can cause unusually high and persistent levels of ozone
pollution.
To help minimize ozone air pollution levels:
- Limit the use of gasoline powered lawn and garden equipment until
the evening hours
- 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 quality index (AQI) levels are Unhealthy for Sensitive
Groups (orange), people with heart or lung disease, pregnant women,
children, and older adults should limit prolonged or heavy outdoor
exertion. When air quality reaches Unhealthy (red) AQI levels,
everyone may experience adverse health effects and sensitive groups
should avoid prolonged time outdoors. At Very Unhealthy (purple) AQI
levels, sensitive groups should avoid all outdoor physical activity
and everyone else should avoid prolonged or heavy outdoor exertion.
To view current and forecasted air quality levels, visit the South
Coast Air Quality Management District website at aqmd.gov or download
the mobile app at www.aqmd.gov/mobileapp. Additional details for
this air quality alert may be available at www.aqmd.gov/advisory.
For the additional information, call the South Coast Air Quality
Management District.
