Forecast issued by the Met Office at 10:30am, Friday 20th April
Local flooding is possible from surface water across much of England and Wales from tomorrow (Saturday) afternoon until Sunday morning as a result of locally heavy, thundery showers. Land, roads and some properties may flood and there may be travel disruption.
The river flood risk is VERY LOW for the next five days, despite the possibility of heavy, thundery showers on Saturday afternoon and overnight into Sunday. Any river flooding impacts are expected to be minimal and limited to small, fast responding urban catchments.
The coastal/tidal flood risk is VERY LOW for the next five days.
Minor surface water flooding impacts are possible from Saturday afternoon and overnight into Sunday for much of England and Wales, due to heavy, thundery showers - see Specific Area of Concern Map 1. Showers are most likely to develop through central and western parts during Saturday afternoon, moving gradually east or north-east overnight and during Sunday morning. Any impacts are expected to be localised.
The overall surface water flood risk is VERY LOW for the next five days.
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 East Riding of Yorkshire and are expected to slowly rise, but 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.
