Right now
The most recent data we hold from NOAA arrived 4 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 4 July 2026 at 00:30 UTC. It is kept here as a record.
It is the 3rd strongest of the 8 detections recorded within 20 km of this point since 16 March 2026. The last comparable one was on 18 June 2026.
What the source measured
NOAA reported: Flash Flood Warning issued July 3 at 4:23PM CDT until July 3 at 7:30PM CDT by NWS Nashville TN

How we know
7 recorded sources include NOAA; independence is not established by this count.
Our own score for this event is 37 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.
