Blowing dust crept into Salt Lake County on Tuesday morning, April 19, timelapse video from the University of Utah’s Department of Atmospheric Sciences shows.

Footage shows the Wasatch Range disappearing behind what University Professor Jim Steenburgh called the “post-frontal dust.” Air pollutant levels were spiking Tuesday due to the airborne dust, the professor said, which he added was “not good for lungs or snowpack.”

The National Weather Service (NWS) warned blowing dust could suddenly reduce visibility as wind gusts up to 55 mph spread dust over southern and eastern Utah. Credit: University of Utah Department of Atmospheric Sciences via Storyful
