The following is a list of tropical cyclones that affected the U.S. state of Delaware. 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.^[1] 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 1749, at least 111 tropical cyclones, some of which had become extratropical, have affected the state, including 21 which passed over the state.

List of tropical cyclones

Pre-1900

• October 23, 1878 – The Gale of 1878, which makes landfall on North Carolina, brings hurricane-force winds to the entire state of Delaware. The storm drops over 3 inches (76 mm) of rainfall in the northern portion of the state, flooding portions of Wilmington. The winds and rain from the storm damages or destroys many houses statewide. The flooding washes out railroads, roads, and bridges, and destroys many carriages in Dover. Crop damage is severe, as well. The strong winds wreck four ships, in total killing 14. A 7-foot (2.1 m) storm surge in Lewes drowns four when they can't escape the rising waters. Beach erosion is severe, as well. Across Delaware, the hurricane kills 18 and causes $45,000 in damage (1878 USD, $1 million 2008 USD).^[15] It is one of only three storms to bring hurricane-force winds to the state.^[1]

1900–1949

In the days preceding its landfall, Isabel produces strong waves, and upon striking land, the storm causes a 5-foot (1.5 m) storm surge along the Delaware coast. The waves and surge result in beach erosion and overwash. The outer rainbands of Isabel drop around 1 inch (25 mm) of rain, though the storm's large circulation produces strong wind gusts of up to 70 mph (115 km/h). The wind gusts knock down many trees and power lines, causing one of the worst power outages for Conectiv Energy. Damage totals to $40 million (2003 USD, $54.6 million 2019 USD).^[78] Due to the damage, President Bush declares the entire state a disaster area.^[79]

• September 28, 2004 – The remnants of Hurricane Jeanne, combined with two cold fronts, produce heavy rainfall peaking at 8.01 inches (203 mm) in Newark. The precipitation leads to rising rivers, including the Red clay Creek which crests at 13.59 feet (4.14 m) The rainfall also floods roads in the northern portion of the state, resulting in trapped vehicles.^[85] The remnants of Jeanne also spawn an F2 tornado in northern New Castle County. The tornado's 5 miles (8.0 km) path includes moving through the New Castle Airport and several buildings. The tornado damages numerous planes and buildings at the airport and injures five people. Damage totals to around $1 million (2004 USD).^[86]
• July 8, 2005 – The extratropical remnants of Hurricane Cindy move through the state, producing heavy rainfall of up to 4.55 inches (116 mm) in Delmar.
