Right now
The most recent data we hold from NOAA arrived 27 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 22 June 2026 at 01:45 UTC. It is kept here as a record.
No stronger detection stands among the 73 recorded within 20 km of this point since 11 March 2026 — 14 others scored the same. Another comparable one was recorded here earlier the same day. 8 more were recorded here in the fortnight before it.

How we know
9 recorded sources include NOAA; independence is not established by this count.
Our own score for this event is 58 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.

Safety Information
If a tornado warning is issued: go to a basement or an interior room on the lowest floor, away from windows. A vehicle and a mobile home are not shelter. Cover your head and neck. Wait for the official all-clear before going outside, and watch for downed power lines and gas leaks afterwards.
Series begins 8 March 2026. Comparisons refer to that period only. Collection gap: 14-26 August 2026.
