Dust Storm Warning
A dust storm warning (SAME code: DSW) is issued by the National Weather Service in the United States when blowing dust is expected to frequently reduce visibility to or less, generally with winds of or more. Beginning November 1, 2018, the National Weather Service issued these dust storm warnings in a polygon- and storm-based format, similar to the format of severe thunderstorm and tornado warnings. The zone-based dust storm warning was replaced by the new blowing dust warning. In addition to the new dust storm warning format, a lesser-impact dust advisory will be issued by the National Weather Service if the criteria for a warning is not met and if travel impacts are still expected. Example The following is the first issuance of the new "storm-based" dust storm warnings, which is in use as of June 19, 2018.

Dust Storms
A dust storm, also called a sandstorm, is a meteorological phenomenon common in arid and semi-arid regions. Dust storms arise when a gust front or other strong wind blows loose sand and dirt from a dry surface. Fine particles are transported by saltation and suspension, a process that moves soil from one place and deposits it in another. The arid regions of North Africa, the Arabian peninsula, Central Asia and China are the main terrestrial sources of airborne dust. It has been argued that poor management of Earth's drylands, such as neglecting the fallow system, are increasing the size and frequency of dust storms from desert margins and changing both the local and global climate, as well as impacting local economies. The term ''sandstorm'' is used most often in the context of desert dust storms, especially in the Sahara Desert, or places where sand is a more prevalent soil type than dirt or rock, when, in addition to fine particles obscuring visibility, a consid ...
