Right now
The most recent data we hold from NOAA arrived 5 minutes ago, and this point is not in it. We record detections, not passes: an absence is not proof that nothing is there.
11 other detections within 20 km in the last 24 hours, the nearest 6 km from here.
This alert expired on 24 September 2026 at 02:16 UTC. It is kept here as a record.
No stronger detection stands among the 27 recorded within 20 km of this point since 16 March 2026 — 18 others scored the same. Another comparable one was recorded here earlier the same day. 14 more were recorded here in the fortnight before it.

How we know
2 recorded sources include NOAA; independence is not established by this count.
Our own score for this event is 16 out of 100.

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