  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.

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.

...AIR QUALITY ALERT FOR AIR POLLUTION DUE TO ELEVATED OZONE AND
ELEVATED LEVELS OF FINE PARTICLE MATTER...

The South Coast AQMD has issued an air quality alert in inland parts
of the South Coast Air Basin and the Coachella Valley due to high
levels of ozone (smog). The air quality alert is in effect 11 AM
Wednesday through 7 PM 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.

Exposure to particle pollution can cause serious health problems,
aggravate heart and lung disease, cause asthma attacks and acute
bronchitis, and increase risk of respiratory infections. People with
respiratory or heart disease, older adults, and children are
particularly susceptible.

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
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

To help keep indoor air clean during periods of poor air quality,
close all windows and doors and run your air conditioner and/or an air
purifier. If possible, do not 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. Limit the use of gasoline powered
lawn and garden equipment.

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.

In the South Coast Air Basin and Coachella Valley, 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
