Right now
The most recent data we hold from NOAA arrived this minute, 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 7 July 2026 at 16:45 UTC. It is kept here as a record.
It is the 3rd strongest of the 109 detections recorded within 20 km of this point since 10 March 2026. The last comparable one was on 5 July 2026. 11 more were recorded here in the fortnight before it.

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