Right now

This alert expired on 3 June 2026 at 13:30 UTC. It is kept here as a record.

It is the 23rd strongest of the 67 detections recorded within 20 km of this point since 8 March 2026. Another comparable one was recorded here earlier the same day. 2 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.

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