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 23 July 2026 at 17:45 UTC. It is kept here as a record.

No stronger detection stands among the 6 recorded within 20 km of this point since 9 May 2026 — 5 others scored the same. Another comparable one was recorded here earlier the same day. 2 more were recorded here in the fortnight before it.

What the source measured

NOAA reported: Tropical Storm Warning issued July 22 at 10:33PM CDT by NWS New Orleans LA

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.
