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.
Nothing else has been detected within 20 km in the last 24 hours.
This alert expired on 27 May 2026 at 02:45 UTC. It is kept here as a record.
No stronger detection stands among the 11 recorded within 20 km of this point since 27 May 2026 — 7 others scored the same. Another comparable one was recorded here earlier the same day. One more was recorded here in the fortnight before it.
What the source measured
NOAA reported: Severe Thunderstorm Warning issued May 26 at 8:55PM CDT until May 26 at 9:45PM CDT by NWS Corpus Christi TX
Urban PEI: 1,526,656 within a heuristic 50 km radius; not unique people.
How we know
6 recorded sources include NOAA; independence is not established by this count.
Our own score for this event is 52 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.
