The storm cells/summary endpoint provides an overall summary of current storm cells based on search/filter criteria. Example uses include obtaining the number of storm cells, maximum amount of hail currently reported within storm cells, or number of storm cells with a high probability of hail within a 50-mile radius. This endpoint can also provide polygons of the storm cell groups included in the summary. Storm cells/summary coverage area includes all 50 US states, as well as Puerto Rico and Guam.

Requests

Every request to the endpoint must include one of the supported actions in the url.
