Right now
The most recent data we hold from NOAA arrived 2 minutes ago, and this point is not in it. We record detections, not passes: an absence is not proof that nothing is there.
This alert expired on 17 May 2026 at 00:45 UTC. It is kept here as a record.
What the source measured
NOAA reported: Severe Thunderstorm Warning issued May 16 at 7:19PM CDT until May 16 at 7:45PM CDT by NWS Hastings NE
How we know
10 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.
