Right now
The most recent data we hold from NOAA arrived 3 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 22 May 2026 at 21:00 UTC. It is kept here as a record.
It is the 4th strongest of the 38 detections recorded within 20 km of this point since 12 March 2026. Another comparable one was recorded here earlier the same day. 2 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.
