…BLOWING DUST ADVISORY IN EFFECT FROM 3 PM TO 10 PM MST
WEDNESDAY…
…EXTREME HEAT WARNING REMAINS IN EFFECT UNTIL 8 PM MST FRIDAY…

* WHAT…Strong thunderstorms with organized outflow wind gusts of
45-55 mph will result in blowing dust, reducing visibility between
one-quarter mile and one mile at times. Haboob formation is
possible. Dense blowing dust will initially develop across
southeast Pima and western Santa Cruz counties during the late
afternoon and spread west to northwest across the Tohono O’odham
Nation and into western Pima and southeast Pinal counties through
the evening. Dangerously hot conditions with high temperatures
ranging between 103 to 110 degrees and low temperatures 79 to 85
degrees. Major HeatRisk is expected.

* WHERE…Pinal County, Tohono O’odham Nation, Tucson Metro Area, and
Western Pima County.

* WHEN…For the Extreme Heat Warning, until 8 PM MST Friday. For the
Blowing Dust Advisory, from 3 PM to 10 PM MST Wednesday.

* IMPACTS…Blowing dust can restrict visibilities below a mile
posing a significant hazard to motorists. In addition, strong and
gusty winds will likely suspend dust into the air that people and
animals breathe. Individuals with heart disease and respiratory
sensitivities may want to reduce their level of exertion to limit
the dust they breathe into their lungs, especially if they are near
dust prone locations. Those most at risk may feel better if they
avoid outside exercise today, keeping windows and doors closed to
help reduce exposure. For the Extreme Heat Warning…heat related
illnesses increase significantly during extreme heat events.

PRECAUTIONARY/PREPAREDNESS ACTIONS…

Persons with respiratory problems should make preparations to stay
indoors until the storm passes. Be ready for a sudden drop in
visibility to near zero. If you encounter blowing dust or blowing
sand on the roadway or see it approaching, pull off the road as far
as possible and put your vehicle in park. Turn the lights all the way
off and keep foot off the brake pedal. Remember, ‘Pull Aside, Stay
Alive’.

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 is an
emergency! Call 9 1 1.

Take extra precautions if you work or spend time outside. When
possible, reschedule strenuous activities to early morning or
evening. Know the signs and symptoms of heat exhaustion and heat
stroke. Wear lightweight and loose fitting clothing when possible and
drink plenty of water.
