Which 1960 hurricane affected every U.S. East Coast state with hurricane-force winds?

Hurricane Donna was the 1960 hurricane that affected every U.S. East Coast state with hurricane-force winds.

Donna developed south of Cape Verde on August 29, 1960, and became a powerful Cape Verde hurricane. It intensified to peak winds of about 160 mph near the Leeward Islands before moving through the Bahamas and striking the Florida Keys as a Category 4 hurricane on September 10.

After crossing Florida, Donna turned northeast and tracked along the Eastern Seaboard. It brought hurricane-force winds from Florida through the Mid-Atlantic and into New England, including the coastal states from North Carolina to Maine. The eye crossed Long Island, and Donna became extratropical over Maine on September 13.

A common mix-up is confusing this distinction with landfall: Donna did not make a hurricane landfall in every coastal state. Rather, its wind field affected every East Coast state. The storm caused 50 deaths in the United States, extensive flooding and storm surge, and roughly $387 million in U.S. damage in 1960 dollars.
