The October 2013 North American storm complex was a massive blizzard and tornado outbreak that affected the Northwest, Rockies, and much of the Midwest in early-October 2013. A total of 22 tornadoes were confirmed as the system moved eastward across the eastern half of the United States, including two that were rated EF4. The storm was unofficially named Winter Storm Atlas by The Weather Channel.
Additionally, the system's tail end cold front absorbed the remnants of Tropical Storm Karen, later becoming a nor'easter off the East Coast of the United States and caused minor flooding in a few states, including Delaware, Georgia, New Jersey, and Pennsylvania.
