The southeastern part of Norway experienced during the 1995 spring the highest flood recorded since the devastating flood in July 1789. The snow storage was at the end of April 30 to 50 percent above the average for the period 1961–90. The weather in May was cold, and the snow depth in the mountains even increased after snowfall during the first two weeks in May. A preliminary notice of the risk of flooding was released in early May by the National Flood Forecasting at the Norwegian Water Resources and Energy Administration (NVE). The snow conditions in the Glornma River Basin (41,500 km²) was monitored closely during May by means of field visits and satellite data.
