IEM :: Storm Based Warning Stats

Storm Based Warning Geometry Statistics

Pick a time period of your choice and get back a summary table of storm based warning polygon statistics. You should be able to highlight this table and paste it into Excel, if you wish. Please note that prior to formal implementation of Storm Based Warnings, the polygons were not the official warning and so their shape may not have been accurately representing the threat.
Note: Areal flood warning polygons have only been issued since summer of 2007.
Perimeter values are in kilometers and area values in square kilometers.
