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 1⁄4 mile (400 m) or less, generally with winds of 25 miles per hour (40 km/h) or more.[1]
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.[2]
Exampleedit
The following is the first issuance of the new "storm-based" dust storm warnings, which is in use as of June 19, 2018.[3]
