Right now
The most recent data we hold from NOAA arrived 29 minutes ago, and this point is not in it. We record detections, not passes: an absence is not proof that nothing is there.
This alert expired on 10 July 2026 at 19:45 UTC. It is kept here as a record.
What the source measured
NOAA reported: Flood Warning issued July 10 at 12:43PM CDT until July 10 at 2:45PM CDT by NWS Memphis TN

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.

After flooding, avoid contact with floodwater which may contain sewage, chemicals, or debris. Follow local emergency service guidance.
