Update on Storm Dennis

Flooding in Yorkshire Dales following Storm Dennis, 15-16 February 2019

Storm Dennis led to extensive flooding over the weekend 15-16 February. The Environment Agency (EA) has advised continued vigilance as more flooding is expected later in the week due to delayed catchment response times and further wet and windy conditions.

On Sunday 16 February, major incidents (threat to life) were declared in South Wales, Herefordshire, Worcestershire and Shropshire due to flooding. There are five severe flood warnings in place around the River Teme in Worcestershire and the River Wye in Herefordshire and a record number of flood warnings have been issued across England. Significant river and surface water flooding is expected to continue with river levels remaining high especially in York, the West Midlands, Derbyshire, Nottinghamshire and the South of England.

One of the worst-hit areas in South Wales was the village of Nantgarw, Rhondda Cynon Taff, near Cardiff, which has seen entire streets left underwater since the early hours of Sunday morning. The storm has claimed the life of a man in his sixties who died after falling into the River Tawe near Gorsedd Park in the Ystradgynlais area of South Wales.

As of 10am on 17 February, the NFU had received reports that thousands of acres of farmland have flooded in Yorkshire and Worcestershire.
