taken to lessen the impact of the extreme heat.
Stay indoors and seek air-conditioned buildings. Drink water, more
than usual, and avoid dehydrating alcoholic, sugary, or caffeinated
drinks. Dress for the heat - lightweight and light-colored clothing.
Eat small meals and eat more often. Monitor those with a higher
vulnerability to heat, including small children. Check in on family,
friends, and neighbors, especially the elderly. If engaging in
outdoor activity, take longer and more frequent breaks and avoid the
hottest parts of the day. Never leave kids or pets unattended in
cars.
Public cooling shelters are available in some areas. Consult county
officials for more details, which may include guidance for proper
social distancing measures.
Recognize the signs and symptoms of heat-related illness. Early
signs include thirst and muscle cramps. Heat exhaustion may include:
cool, moist, pale skin; headache; dizziness; weakness or exhaustion;
nausea. The most serious illness is heat stroke, which may include:
vomiting; confusion; throbbing headache; decreased alertness or loss
of consciousness; high body temperature (above 105F); hot, dry skin;
rapid, weak pulse; rapid, shallow breathing; seizures.
Heat stroke can be DEADLY. Treat as an emergency and call 9 1 1.
Continue to monitor NWS forecasts, broadcast outlets, and local
government for updates.

The Arizona Department of Environmental Quality (ADEQ) has issued an
Ozone High Pollution Advisory for the Phoenix Metro Area on Saturday

This means that forecast weather conditions combined with existing
ozone levels are expected to result in local maximum 8-hour ozone
concentrations that pose a health risk. Adverse health effects
increase as air quality deteriorates.
Ozone is an air contaminant which can cause breathing difficulties
for children, older adults, as well as persons with respiratory
problems. A decrease in physical activity is recommended.
You are urged to car pool, telecommute or use mass transit.
The use of gasoline-powered equipment should be reduced or done late
in the day.

This Hazardous Weather Outlook is for northwest Colorado, southwest
Colorado, west central Colorado, east central Utah, northeast Utah
and southeast Utah.
.DAY ONE...Today and tonight.
High pressure building into the area today will allow drier air to
build in as well, leading to a downturn in shower and storm activity
compared to previous days. Look for storms to develop over the higher
terrain this afternoon and evening. The main threats will be gusty
winds, frequent lightning, as well as some brief heavy rain and maybe
small hail. Temperatures will be around 5 degrees warmer today.
.DAYS TWO THROUGH SEVEN...Sunday through Friday.
The next push of subtropical moisture looks to arrive on Sunday,
bringing a return of widespread shower and thunderstorm activity.
These storms will be capable of producing prolonged heavy rain and
the threat for flash flooding will be on the increase Sunday into
Monday. Another round of increased activity will be possible
Wednesday and Thursday before drier air once more tries to build in
overhead late in the week.
.SPOTTER INFORMATION STATEMENT...
Spotter activation is not expected today or tonight, however
spotters are encouraged to relay rainfall amounts or any observed
flooding to the National Weather Service in Grand Junction.
