Rain radar images running from 1200 local time (LT) 26 August 2010, with steps of
one hour (left-to-right, top to bottom) until 0200 LT 27 August. A relatively thin
line of high precipitation intensity (red colours) oriented in the southwest-northeast
direction, and slowly moving in the northeast direction, is embedded in a larger
area with lighter precipitation (white and grey colours). During this event more
than 130 mm of precipitation fell in the eastern part of the Netherlands.
On the 26th and 27th August 2010 more than 130 mm precipitation was recorded in the
eastern part of the Netherlands, leading to severe local flooding. The KNMI station
Lievelde recorded 138 mm on the morning of 27th of August; the third highest daily
precipitation amount recorded at a Dutch precipitation station after 1950. In the
E-OBS observational data set, which is based on observations aggregated on a grid
of 25 km, it is even the most extreme event. More information on this event, and
the question how this event could change in the future is presented here.
On the 28th June 2011, during a severe shower, 79 mm of rain was recorded between

Netherlands. More information on this event, and the question how this event could
change in the future is presented here.
