River and Aravaipa Valleys including Clifton/Safford-
...BLOWING DUST ADVISORY REMAINS IN EFFECT UNTIL 8 PM MST THIS
EVENING...
* WHAT...Scattered thunderstorms with strong thunderstorm outflow
wind gusts of 45-55 mph will result in blowing dust reducing
visibility between one-quarter mile and one mile at times. Blowing
dust is especially likely across the San Simon Valley in eastern
Cochise county, along Interstate 10 between Willcox and the New
Mexico state line and near the Willcox Playa.
* WHERE...Eastern Cochise County below 5000 feet, Upper Gila River
Valley, and Upper San Pedro River Valley.
* WHEN...Until 8 PM MST this evening.

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.
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'.
