The Environment Agency (EA) will run its annual test of flood sirens in Grimsby and Cleethorpes on Friday, August 24.
Installed after the summer floods of 2007, 17 of the 18 sirens help the EA warn over 25,000 households and local businesses of imminent tidal flooding while one also warns of flood risk from the river.
Testing will take place on Friday, 24 August between 10am and 12pm.
If you hear the sirens during this time, you do not need to take any action.
If flooding is expected on the day, the test will be rescheduled and flood warnings will be issued through the Environment Agency’s free Flood Warning Service (FWS).
Greg Smith, Flood Resilience team leader at the EA, said: “It’s important that we conduct these annual tests to make sure the sirens still work as they should.
“Although our flood defences reduce the risk of flooding to thousands of homes and businesses in Grimsby and Cleethorpes, we can never remove the risk of flooding entirely.”
On the flood siren testing day, North East Lincolnshire Council staff and its partner Engie will be joining the Environment Agency in Freshney Place Shopping Centre between 9am and 5pm to answer any questions on flood risk and how you can prepare.
