Right now
The most recent data we hold from NOAA arrived 21 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 05:00 UTC. It is kept here as a record.
What the source measured
NOAA reported: Severe Thunderstorm Warning issued May 16 at 11:41PM CDT until May 17 at 12:00AM CDT by NWS Hastings NE
How we know
45 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.
