What is the farthest distance inland that a hurricane has traveled in the United States?
Since hurricane record-keeping began in 1949, nine storms have begun their lives as either Atlantic hurricanes or tropical storms (i.e., sustained winds of at least 34 mph) and moved across North America to become Northeast Pacific hurricanes, or vice versa. Two examples are Atlantic Hurricane Cesar in July 1996, which became Northeast Pacific Hurricane Douglas. Another is Pacific Hurricane Cosme (June 1989), which became Atlantic Tropical Storm Allison. It is important to remember, however, that these hurricanes did not travel across the large land mass as hurricanes but were downgraded to tropical storms and then depressions, then rebuilt when they encountered the opposite ocean.
