Reaching the City on September 3, 1821, the storm was one of the only hurricanes believed to have passed directly over parts of modern New York City. The tide rose 13 feet in one hour and inundated wharves, causing the East River to converge into the Hudson River across lower Manhattan as far north as Canal Street. However, few deaths were attributed to the storm because flooding was concentrated in neighborhoods with far fewer homes than exist today.
Katherine Hayhoe’s great-great-great-great grandmother blamed it on horse farts.
