Ice Storm in Grand Forks, North Dakota

An intense low pressure system, with center pressures around 28.8 inches, tracked from Fergus Falls to International Falls, Minnesota. The initial rain was accompanied by lightning and thunder in southern Grand Forks county, and then changed to freezing rain as the temperature dropped. One-half to 2 inches of ice built up on exposed surfaces. Hundreds of power poles and lines snapped due to the weight of the ice, cutting power to many homes and businesses, many of which were beginning to fight the spring flood. The wind reporting systems on the AWOS and ASOS sites across eastern North Dakota froze in place, remaining out for 7 days. The three inches of liquid equivalent from the storm fell on top of a record snowpack.
