A haze over Tucson Friday morning is caused by dust, not smoke from a small wildfire in the Rincon Mountains, and could create conditions for a haboob by the afternoon.

The haze is expected to hang over Tucson throughout the morning. By 2 p.m. the National Weather Service said blowing dust is expected. The agency has issued a weather advisory that will last until 9 p.m. Friday night.

Blowing dust is expected to restrict visibility to a quarter mile to a mile, according to the Weather Service. Motorists should drive with caution.

In the advisory, forecasters predict: “Strong and gusty thunderstorm outflows should initially develop across eastern Pima County, Southeast Pinal County and the Tohono O’odham 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.”

High temperatures are expected to range from 98 to 104 degrees in Tucson and surrounding areas and chances of rain are at 40 percent, the Weather Service stated.
