With Interactive Hail Maps you can overlay multiple hail dates over the same map for any date range. Zoom in the area you would like to search and then click the Hail Finder button. A list of dates will appear on the left hand side of the map where hail was detected by radar only in the screen’s view area.
Now click on any date to view its hail map or click “Combine” to see every hail map date overlay on the same map.
