Right now
The most recent data we hold from NOAA arrived 69 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 13 May 2026 at 17:15 UTC. It is kept here as a record.
It is the 2nd strongest of the 131 detections recorded within 20 km of this point since 8 March 2026. Another comparable one was recorded here earlier the same day. 74 more were recorded here in the fortnight before it.

How we know
One source: NOAA. Not yet confirmed by a second, independent source.
Our own score for this event is 34 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
During flooding: never walk, swim, or drive through floodwaters. Six inches of moving water can knock you down, and one foot of water can sweep away a vehicle. Move to higher ground if waters rise. After flooding, avoid contact with floodwater which may contain sewage, chemicals, or debris. Follow local emergency service guidance.
Series begins 8 March 2026. Comparisons refer to that period only. Collection gap: 14-26 August 2026.
