Right now

The most recent data we hold from NOAA arrived 2 hours 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 20 May 2026 at 21:15 UTC. It is kept here as a record.

No stronger detection stands among the 6 recorded within 20 km of this point since 1 May 2026 — one other scored the same. Another comparable one was recorded here earlier the same day. One more was recorded here in the fortnight before it.

How we know

One source: NOAA. Not yet confirmed by a second, independent source.

Our own score for this event is 43 out of 100, at 80 % confidence.

The score is ours, computed from intensity, exposed population and local history — not the source’s.

Computed under scoring rules v1. Rows carrying other versions were judged by different rules and are not directly comparable.

Safety Information

During flooding: never walk, swim, or drive through floodwaters. Six inches of moving water can knock you down, and one foot of water can sweep away a vehicle. Move to higher ground if waters rise. After flooding, avoid contact with floodwater which may contain sewage, chemicals, or debris. Follow local emergency service guidance.

Series begins 8 March 2026. Comparisons refer to that period only. Collection gap: 14-26 August 2026.

This data is aggregated algorithmically from scientific sources. Not a replacement for official emergency warnings.
