Right now
The most recent data we hold from SPC arrived 51 minutes ago, and this point is not in it. We record detections, not passes: an absence is not proof that nothing is there.
11 other detections within 20 km in the last 24 hours, the nearest <1 km from here.
Reported by SPC today.
No stronger detection stands among the 125 recorded within 20 km of this point since 24 March 2026 — 6 others scored the same. Another comparable one was recorded here earlier the same day. 14 more were recorded here in the fortnight before it.

How we know
2 recorded sources include SPC; independence is not established by this count.
Our own score for this event is 32 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 v5. Rows carrying other versions were judged by different rules and are not directly comparable.
