Flood Guidance Statement, 21 February 2017 info

Rain today (Tuesday) into tomorrow (Wednesday) will ‘wet up’ catchments, with a chance of minor river flooding impacts across southern Pennine catchments tomorrow (Risk Area A). On Thursday, persistent and occasionally heavy precipitation will affect the north of England. Some of this is expected to fall as snow on the hills but there is a chance of some minor river flooding impacts across the north-east of England where rain falls into sensitive catchments with already high river flows (Risk Area B). There is a low likelihood of minor impacts continuing in York through Friday. On Saturday, there is the potential for heavy, persistent rain coupled with snowmelt across parts of the north of England to result in significant impacts (Risk Area C). Localised minor river flooding impacts are also possible across north Wales (Risk Area D).

On Thursday, persistent and occasionally heavy precipitation will affect the north of England. This is expected to fall as snow on the hills, but there is a low likelihood of minor impacts where it falls as rain at lower levels. On Saturday, heavy, persistent rain may fall across upland parts of the north of England (Risk Area C). Given the wet conditions during this week and the risk of some snowmelt from the mountains increasing run-off, this contributes to the potential for significant surface water flooding impacts. Localised minor surface water flooding impacts are also possible across north Wales (Risk Area D).

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

The coastal/tidal flood risk is VERY LOW for the next five days. Strong winds bring a low likelihood of minor coastal impacts along the Yorkshire coast at times between Wednesday and Friday.
