This alert expired on 11 July 2026 at 18:00 UTC. It is kept here as a record.
It is the 6th strongest of the 65 detections recorded within 20 km of this point since 16 March 2026. The last comparable one was on 7 July 2026. 12 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.
