River Dun
Water levels in the River Dun continue to fall slowly following drier weather over the last 12 hours. Today (Monday 17/02/2020), small amounts of rain are forecast, but it won’t be enough for the river to flood property. Over the next 24 hours there will be significant out of bank flooding affecting land and roads at West Dean and Dunbridge. Tomorrow (18/02/2020) and through until Thursday (20/02/2020) rain is expected each day. Forecast rainfall totals are not large, but the river will be very sensitive to any further rainfall and it may still cause minor impact flooding. We continue to monitor the forecast. We would like residents to remain prepared for further flood impacts this week. This Flood Alert will be updated by 12:00 on 18/02/2020.

River Dun
Water levels in the River Dun remain high following the heavy rainfall yesterday, but are currently continuing to fall. Today (16/01/2020), the forecast rainfall totals have increased, with up to 30mm expected. This is a large volume of rain and should that affect the river, then levels will rise quickly and could cause the river to flood Rectory Road, near to the railway line at West Dean. The rain will affect Hampshire from lunchtime today. Over the next 24 hours, the river could be higher than normal. Drier weather is forecast at the weekend, so the situation should then improve. Our staff will keep the river free of any reported blockages. Residents in lower lying properties should remain prepared for flood impacts. Today and overnight, we recommend that cars are not parked near to the river. This message will be updated by 12:00 on 17/01/2020.
