On February 5, the first major snow storm of 2010 pounded the East. New Jersey to Washington, DC received more than 20 inches of snow, closing interstates and shutting down rails. The blizzard was followed four days later by another major snow dump. From February 9-11, Philadelphia to Washington, DC received another 16-20 inches of snow. The winter storms prompted President Obama to refer to the weather system as 'Snowmageddon'.
