Septem– A tropical storm crosses over southeastern Delaware.Aug– A Category 2 hurricane parallels the Delmarva Peninsula after striking North Carolina, though effects, if any, are unknown.It is one of only three storms to bring hurricane-force winds to the state. Across Delaware, the hurricane kills 18 and causes $45,000 in damage (1878 USD, $1 million 2008 USD). A 7-foot (2.1 m) storm surge in Lewes drowns four when they can't escape the rising waters. The strong winds wreck four ships, in total killing 14. The flooding washes out railroads, roads, and bridges, and destroys many carriages in Dover. The winds and rain from the storm damages or destroys many houses statewide. The storm drops over 3 inches (76 mm) of rainfall in the northern portion of the state, flooding portions of Wilmington. Octo– The Gale of 1878, which makes landfall on North Carolina, brings hurricane-force winds to the entire state of Delaware.Octo– An extratropical storm, once a Category 3 hurricane, crosses the state, causing several ship wrecks in the Chesapeake and Delaware Bays.Septem– With winds of 70 mph (115 km/h), a tropical storm moves across Delaware.Octo– A tropical storm crosses the state, with no known effects.Septem– A tropical storm crosses the state from south to north.Septem– After weakening from a hurricane, a tropical storm moves northward through Delaware.Aug– A tropical storm parallels the coastline of the Delmarva Peninsula, though impact, if any, is unknown.Septem– Many ships report calls of distress due to powerful winds from a hurricane.

Aug– A hurricane crosses the state, causing gale-force winds along the coast.

Octo– A hurricane impacted the Mid-Atlantic, and impacts were observed in Delaware, but it's unclear at what strength the storm was when it impacted the state.

Since 1749, at least 111 tropical cyclones, some of which had become extratropical, have affected the state, including 21 which passed over the state. The state often experiences the direct effects of landfalling North Atlantic tropical cyclones and from the remnants of some Pacific storms, such as rainfall or strong winds, as well as the effects of storms that remain offshore, such as rip currents or heavy surf. Since reliable records began, no tropical cyclone has struck the state while maintaining hurricane intensity, and only two storms since 1851 caused hurricane-force winds in the state. The following is a list of tropical cyclones that affected the U.S. Track map of all tropical cyclones that passed over Delaware from 1851 to 2005
