Right now
The most recent data we hold from NOAA arrived 18 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 30 July 2026 at 22:30 UTC. It is kept here as a record.
No stronger detection stands among the 69 recorded within 20 km of this point since 1 April 2026 — 15 others scored the same. Another comparable one was recorded here earlier the same day. 23 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.
