How to read this
Fact: each shape is an active NWS Severe Thunderstorm Warning polygon carrying a positive structured maximum hail-size value. Limit: the stated size is a hazard estimate, not a measurement everywhere in the polygon. Warnings without geometry remain listed. This map is not a forecast, loss estimate or substitute for official instructions.
