Deadly dust storm seen from space

Posted: Updated:

On Tuesday afternoon high winds blew across dry desert land and fallow farm fields in Pinal County to blow fingers of dust across Interstate 10 near Picacho Peak. 

These areas of blowing dust were very shallow but thick in spots, which reduced visibility to near zero for drivers. 

The conditions proved deadly. 

Three people died in an accident that included over a dozen cars and trucks. 

The fingers of dust, although shallow, could be seen from space with a special imager on a National Oceanic and Atmospheric Administration (NOAA) satellite.  

Below is the image from the satellite with additional information Tweeted by the Tucson National Weather Service (NWS) office located on the University of Arizona campus.  

The Tucson NWS circled the line of dust that appeared on the satellite imagery at around 1:10 in the afternoon. 

This was about an hour after the accident. 

The dust would blow over the highway, reducing visibility for only minutes at a time before heading off to the northeast. 

The image was taken by the a NOAA satellite by an instrument called the Visible Infrared Imaging Radiometer Suite (VIIRS)

This instrument was developed by Raytheon.
