Right now
The most recent data we hold from NOAA arrived 23 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 24 June 2026 at 18:30 UTC. It is kept here as a record.
It is the 122nd strongest of the 209 detections recorded within 20 km of this point since 1 April 2026. Another comparable one was recorded here earlier the same day. 183 more were recorded here in the fortnight before it.

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.
