Michigan/the Great Lakes region as a tropical storm. Four people were killed in Washington, D.C. due to a traffic accident. In the Chesapeake Bay, Connie capsized a boat, killing 14 people and prompting a change in Coast Guard regulation. There were six deaths each in Pennsylvania and New Jersey, and eleven deaths in New York, where record rainfall flooded homes and subways. At least 225,000 people lost power during the storm. Damage in the United States totaled around $86 million, although the rains from Connie was a prelude to flooding by Hurricane Diane. The remnants of Connie destroyed a few houses and boats in Ontario and killed three people in Ontario. Hurricane Diane A tropical wave spawned a tropical depression between the Lesser Antilles and Cape Verde on August 7. It slowly strengthened and became Tropical Storm Diane on August 9. After a Fujiwhara interaction with Hurricane Connie, Diane curved northward or north-northeastward and quickly deepened. By early on August 8, the storm was upgraded to a hurricane. Only several hours later, Diane peaked as a Category 2 hurricane with winds of . The storm resumed its west-northwestward motion on August 13. Colder air in the region caused Diane to weaken while approaching the East Coast of the United States. A recently installed radar in North Carolina noted an eye feature, albeit poorly defined. Early on August 17, Diane made landfall near Wilmington, North Carolina, as a strong tropical storm. The storm then moved in a parabolic motion across North Carolina and the Mid-Atlantic before re-emerging into the Atlantic Ocean on August 19. Diane headed east-northeastward until becoming extratropical on August 20. Despite landfall in North Carolina, impact in the state was minor, limited to moderate rainfall, abnormally high tides, and relatively strong winds. Further north, catastrophic flooding occurred in Pennsylvania, New Jersey, New York, and New England. Of the 287 stream gauges in the region, 129 reported record levels after the flooding from Tropical Storm Diane. Many streams reported discharge rates that were more than twice of the previous record. Most of the flooding occurred along small river basins that rapidly rose within hours to flood stage, largely occurring in populated areas; the region in which the floods occurred had about 30 million people, and 813 houses overall were destroyed. The floods severely damaged homes, highways, power lines, and railroads, and affected several summer camps. Overall utility damage was
