Nothing else has been detected within 20 km in the last 24 hours.

This alert expired on 3 August 2026 at 06:45 UTC. It is kept here as a record.

No stronger detection stands among the 39 recorded within 20 km of this point since 18 June 2026 — 14 others scored the same. Another comparable one was recorded here earlier the same day. 5 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.
