River

The river flood risk is VERY LOW for the next five days, despite the possibility of heavy, thundery showers this (Saturday) afternoon and on Sunday. Any river flooding impacts are expected to be minimal and limited to small, fast responding urban catchments.

Coastal

The coastal/tidal flood risk is VERY LOW for the next five days.

Surface

The surface water flood risk is LOW for today (Saturday) and Sunday.

Heavy, thundery showers this (Saturday) afternoon and overnight will affect much of England and Wales. Showers are most likely to develop through central and western parts this afternoon, moving gradually north-east through this evening. Further heavy showers are possible across parts of East Anglia tomorrow (Sunday) afternoon. Minor surface water flooding impacts are probable across the north of England and north-east Wales and possible elsewhere - see Specific Areas of Concern Map 1. Any impacts are expected to be localised.

Groundwater

The groundwater flood risk is VERY LOW for the next five days.

Groundwater levels remain high across parts of Hampshire and West Berkshire, with some ongoing minimal impacts. Levels are not expected to rise further.

Groundwater levels are high in North Yorkshire and the East Riding of Yorkshire and are expected to slowly rise. However, in the absence of further widespread rain over the next few days, levels should begin to plateau and then slowly decline.

No groundwater flooding impacts are currently expected.
