Nothing else has been detected within 20 km in the last 24 hours.
This alert expired on 30 June 2026 at 16:45 UTC. It is kept here as a record.
No stronger detection stands among the 12 recorded within 20 km of this point since 14 March 2026 — 5 others scored the same. 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.
