I particularly remember the Ice Storm of 11-12 February 1994 as it was the first, and still the only, time I witnessed 2" of ice accretion due to freezing rain and sleet. Here is an excerpt from the fantastic Maryland Winters web page, describing the winter of 1993-94 and in particular, the Ice Storm of 11-12 February 1994:
January-February, 1994 Cold and Ice: One storm seemed to come on top of another all dropping snow, sleet, and freezing rain across the state. The most devastating icestorm struck February 10-11. It left a coat of ice, one to three inches thick, from freezing rain and sleet! Meanwhile, across north-central Maryland 4 to 7 inches of sleet accumulated. By far, the hardest hit was an area was about a 50 mile wide band from near Fredericksburg, VA across southern Maryland (Charles, Calvert, St. Marys) up to Annapolis, across the Eastern Shore (Queen Annes, Caroline, and Talbot) and over Sussex and Kent Counties in Delaware. Some counties lost 10 to 20% of their trees from the heavy ice. Trees fell on homes and cars. Roads were blocked and impassable. Electric and phone lines were down with as much as 90 percent of the county's people without power. Outages and damage were so widespread that many people were without power for a week. A presidential disaster declaration was given and damages were estimated at near $100 million. There were numerous injuries from car accidents and people slipping.In Anne Arundel County alone, hospitals reported 104 weather related injuries in two days from the ice. This was likely the iciest winter Maryland has seen this century.
