Right now
The most recent data we hold from NOAA arrived 16 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 19 June 2026 at 09:15 UTC. It is kept here as a record.
What the source measured
NOAA reported: Flood Warning issued June 18 at 10:08AM CDT until June 20 at 12:00PM CDT by NWS New Orleans LA
Urban PEI: 20,480 within a heuristic 50 km radius; not unique people.
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.
