Flood Guidance Statement, 13 February 2020 info

The river flood risk is MEDIUM on Saturday and Sunday. Persistent, heavy rain is forecast from Storm Dennis on Saturday and Sunday and this will fall on responsive catchments across much of England and Wales. Significant river flooding is probable across parts of the south of England, south Wales and some Pennine areas, and is possible in other parts of Wales, the north and south of England and the Midlands. Significant river flooding impacts may continue into the middle of next week on large rivers such as the Yorkshire Ouse and Thames. Minor river flooding is also possible across the rest of the Midlands over the weekend and for central and the south of England on Monday. Minor river flooding impacts are also possible on Friday over the north of England due to snowmelt combining with frontal rain.

The overall surface water flood risk is MEDIUM on Saturday and Sunday. Persistent, heavy rain is forecast from Storm Dennis on Saturday and Sunday and this will fall on saturated catchments across much of England and Wales. Significant surface water flooding is probable across parts of the south and south-west of England, south Wales and some Pennine areas, and is possible in other parts of Wales, the north and south of England and the west and south Midlands. Minor surface water flooding is also possible in other parts of the Midlands on Saturday and Sunday.

The groundwater flood risk is VERY LOW for the next five days. Groundwater levels remain high in Hampshire, Dorset, Wiltshire, North Lincolnshire, East Sussex, West Sussex and Brighton and Hove, although impacts are minimal.

The coastal/tidal flood risk is VERY LOW for the next five days. Minor coastal impacts are possible but not expected today (Thursday) for the north-east and south-west coasts of England parts of the Welsh coast, and parts of the Severn Estuary/Bristol Channel. This is due to a combination of high water levels, coastal gales and large waves in some places.
