Right now

The most recent data we hold from NOAA arrived 6 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 29 May 2026 at 02:45 UTC. It is kept here as a record.

It is the 8th strongest of the 17 detections recorded within 20 km of this point since 7 May 2026. The last comparable one was on 10 May 2026. 4 more were recorded here in the fortnight before it.

What the source measured

NOAA reported: Flood Warning issued May 28 at 9:40AM CDT until May 30 at 1:00AM CDT by NWS Mobile AL

Urban PEI: 46,805 within a heuristic 50 km radius; not unique people.

Nearby, since 7 May 2026

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.

Physical priority index · v1. Heuristic priority, not calibrated probability, predictive accuracy or damage. The legacy data-support index combines assigned source support and field availability. Urban PEI is distance-weighted and does not count unique people; zero does not establish that nobody is present. Model cards.

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.

This data is aggregated algorithmically from scientific sources. Not a replacement for official emergency warnings.
