...BLOWING DUST ADVISORY IN EFFECT FROM 1 PM THIS AFTERNOON TO 10 PM
MST THIS EVENING...
* WHAT...Isolated thunderstorms with strong thunderstorm outflow
wind gusts to 45-50 mph will result in blowing dust lowering
visibility between one-quarter and one mile at times. The threat
for blowing dust will persist into the evening as stronger
sustained east-to-southeast winds 20-30 mph move into the area
from the east.
* WHERE...Eastern Cochise County below 5000 feet and Upper San Pedro
River Valley.

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
