NOAA reported: Severe Thunderstorm Warning issued May 16 at 11:02PM CDT until May 16 at 11:15PM CDT by NWS Hastings NE
How we know
7 recorded sources include NOAA; independence is not established by this count.
Our own score for this event is 22 out of 100.
This is our versioned heuristic index, not source severity or a calibrated probability. Urban PEI does not count unique people.
Computed under scoring rules v1. Rows carrying other versions were judged by different rules and are not directly comparable.
