Snowmageddon (February 2010)
Two blizzards struck within days of each other, dumping 25-30 inches from Virginia to New York, with Elkridge, Maryland recording nearly 40 inches. The back-to-back storms collapsed roofs, stranded vehicles on highways, and shut down federal government operations in Washington D.C. for nearly a week. Six states declared national emergencies. The storms killed 41 people and caused billions in economic losses.
The region took over a week to dig out; some neighborhoods remained inaccessible for days.
The event highlighted infrastructure vulnerabilities and spurred investments in snow removal equipment and emergency response capacity.
Snowmageddon represents compound storm risk—what happens when the Northeast gets hit repeatedly without recovery time, a pattern climate models suggest may become more common.
