Right now
The most recent data we hold from NOAA arrived 1 minute 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 6 June 2026 at 04:00 UTC. It is kept here as a record.
What the source measured
NOAA reported: Severe Thunderstorm Watch issued June 5 at 3:26PM CDT until June 5 at 11:00PM CDT by NWS La Crosse WI

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.
