What does the colored area (swath) indicate?

The hail swath depicts areas that may have been hit by hail, but are not guaranteed to have been hit. The colored areas represent a proprietary algorithm that contours around the maximum size hail as detected by radar as a storm moves through an area over the course of a 24-hour period (6am to 6am). As such, the swaths identify the most likely areas of hail damage.

Some maps, such as the example above, may be labeled for a certain state but have no swaths visible in that state. This is particularly common in smaller states. Swath maps are labeled for the location of the Radar station monitoring the hail activity, but can include locations up to 200 miles away.
