A blowing dust advisory remains in effect from 2 PM this afternoon to 9 PM MST this evening.

* 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 the 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.

* Timing...strong and gusty thunderstorm outflows should initially develop across eastern Pima County...southeast Pinal County and the Tohono Oodham Nation by mid to late afternoon. These outflows will generally track to the northwest... potentially consolidating and forming a haboob. This type of scenario would impact the Interstate 10 corridor northwest of Tucson.

* Winds...thunderstorm outflow winds of 35 to 45 mph...generally blowing towards the northwest.

* Visibility...areas of blowing dust will restrict visibilities below a mile. Locally dense blowing dust will significantly reduce visibilities below a quarter mile.
