Tropical cyclones move into the contiguous United States from the Atlantic Ocean, the Gulf of Mexico, and the eastern Pacific Ocean. The highest rainfall totals in the country have been measured across the Gulf Coast and lower portions of the Eastern Seaboard. Intermediate amounts have been measured across the Southwest, New England, and the Midwest. The northern Great Plains and Pacific Northwest have received the lowest amounts, as those regions lie exceptionally far from the breeding grounds of Atlantic and Eastern Pacific tropical cyclones.
