Winchester Itchen Flood alert 4:41pm, Monday 23rd February

Flooding possible. Be prepared.

Flood alert

High river levels over the next two days may lead to flooding. Flooding is possible on 23/02/2026, following a very wet January and February. Flooding could affect North Walls Recreation Ground and River Park. Winchester City Council have installed flood barriers at Park Avenue, River Park, and Water Lane. From Monday (23/02/2026) to Wednesday (25/02/2026), virtually no rain is forecast, giving the river a chance to recover. Further rainfall is forecast on Thursday & Friday (26/02/2026 & 27/02/2026); if this is realised the river may rise again. River levels will remain higher than normal throughout February and into March. We are liaising with emergency services and local authorities including Winchester City Council regarding sluice operation. This message will be updated by 18:00 on 25/02/2026.
