Dust RGB captures dust event in the Intermountain West…

The MODIS RGB image below captured the dust event in portions of the Intermountain West today, April 14th, as strong winds lifted dust across the drought-stricken region.  NWS offices in the region issued high wind warnings and dust storm warnings due to the conditions.  Visibilities below one quarter mile in some instances were reported with portions of I 80 closed near Tooele, Utah.  The dust is indicated by pinkish colored steaks across portions of Utah and Nevada in the Dust RGB below.

Addendum… I just wanted to update with another image a little later on the 14th to show the evolution of the blowing dust.  The area of dust ahead of the frontal boundary was diminishing by about 2030 UTC in Utah, while the large area of dust continued to impact portions of southern Nevada in strong northwesterly flow in the post-frontal airmass (image below).

  1. Kris, this is a good post to see showing the dust RGB during the day. I am actually using this for the upcoming Southwest Aviation Weather Safety workshop in Las Vegas at the end of the week.
