Right now
The most recent data we hold from NOAA arrived 15 minutes ago, and this point is not in it. We record detections, not passes: an absence is not proof that nothing is there.
Nothing else has been detected within 20 km in the last 24 hours.
This alert expired on 30 June 2026 at 06:00 UTC. It is kept here as a record.
No stronger detection stands among the 59 recorded within 20 km of this point since 15 March 2026 — 18 others scored the same. Another comparable one was recorded here earlier the same day. 29 more were recorded here in the fortnight before it.
What the source measured
NOAA reported: Severe Thunderstorm Warning issued June 30 at 12:21AM CDT until June 30 at 1:00AM CDT by NWS Omaha/Valley NE
Urban PEI: 24,366 within a heuristic 50 km radius; not unique people.
How we know
11 recorded sources include NOAA; independence is not established by this count.
Our own score for this event is 40 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.
