List of SPC High Risk days
From Wikipedia, the free encyclopedia
The following days had a declaration of High Risk of severe weather in a certain part of the United States according to the Storm Prediction Center.
Busts indicate days that a severe weather outbreak was expected but never materialized, with little or no severe activity. Limited details are available for days before the late 1990s.
The only month that has not recorded a known High Risk day is September. No High Risk has ever been issued west of the Rocky Mountains.
