Heavy rainfall/flooding - June 2007

Record June totals and heavy rainfall on 12/15 June (N Ireland & N England) and 24/25 June (Yorkshire and the Humber), resulted in widespread flooding and disruption...

In excess of 150 mm of rain fell over much of Wales, the Midlands, Northern England, Northern Ireland and parts of Scotland and South-west England, with over 250 mm locally. This represents over three times the average June rainfall over much of the West Midlands, Lincolnshire, Yorkshire and the Humber, and over four times the June average in places, as can be seen in the June 2007 per cent of average map below. The estimated average frequency of occurrence (return period) of these high totals is over 200 years (June 2007 - return period map Rainfall anomaly map

24-25 June 2007 - Heavy rainfall/flooding

There was a further significant rainfall event during the month on 24/25 June 2007, affecting Northern England, north Wales and the Midlands, with Yorkshire and the Humber particularly wet on both days. The heavy and prolonged rainfall was caused by a slow moving area of low pressure and associated frontal system. (6-hourly surface animation between 1800 UTC on 24 June 2007 and 0000 UTC on 26 June 2007). The rainfall resulted in thousands of homes and businesses being flooded and disruption to road and rail transport across a wide swathe of northern and western England. Several deaths were attributed to the flooding.
