Track map of all tropical cyclones that passed over Delaware from 1851 to 2005
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 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 108 tropical cyclones, some of which had become extratropical, have affected the state, including 21 which passed over the state.

The storm drops over 3 inches (75 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 wrecked four ships, in total killing 14. A 7 foot (2.1 m) storm surge in Lewes drowned four when they couldn't escape the rising waters. Beach erosion was severe, as well. Across Delaware, the hurricane killed 18 and caused $45,000 in damage (1878 USD, $1 million 2008 USD).[19] It is one of only two storms to bring hurricane-force winds to the state.[1]

The currents result in nearly 100 rescues and four injuries, and also forces beach closures and restrictions. The strong winds and waves cause beach erosion, as well.[85]
- September 16, 1999- Tropical Storm Floyd crosses over the southeastern portion of the state. The storm produces strong wind gusts of up to 64 mph (103 km/h) in Sussex County and heavy rainfall peaking at 10.58 inches (269 mm) in Greenwood, a 24-hour state record. The flooding, which exceeded the 100-year flood return period, kills two and causes record-breaking river levels across the state. Hundreds of roads, railroad lines, and bridges are closed or destroyed, trapping dozens due to flooded vehicles. The winds uproot hundreds of trees, leaving 25,000 homes and businesses without power for 3 days. Floyd damages 171 homes, 44 severely, and destroys 33 in New Castle County. Damage is minimal near the ocean, and amounts to minor beach erosion and tidal flooding. Throughout the state, damage totals to $8.42 million (1999 USD, $10.9 million 2008 USD).

- June 16, 2001- The subtropical remnant of what was once Tropical Storm Allison passes just to the southeast of the state. The storm drops moderate amounts of rainfall, peaking at 4.2 inches (107 mm) in Greenwood, which results in drainage problems yet little damage.[88]
- September 11, 2001- Hurricane Erin generates rough surf and rip currents along Delaware beaches, forcing restrictions and closures.[89]
- July 3, 2003- The remnants of Tropical Storm Bill cross over the state, dropping light rainfall of around 1 inch (25 mm).[90]
- September 15, 2003- Moisture from the remnants of Tropical Storm Henri produce heavy rainfall over portions of Delaware, including a peak of 9.02 inches (229 mm) in Hockessin. The flooding damages hundreds of houses, and traps motorists in submerged vehicles. Several bridges are destroyed or damaged due to rising flood waters, including the Red Clay Creek which peaks at 17.27 feet (5.2 m). Damage totals $16.1 million (2003 USD, $18.9 million 2008 USD).[91] Due to the damage, President George W. Bush declares the state a disaster area.[92]
- September 17, 2003- Hurricane Isabel passes to the southwest of the state as it makes landfall on North Carolina. 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 (112 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 $17.8 million (2003 USD, $20.9 million 2008 USD).[93] Due to the damage, President Bush declares the entire state a disaster area.[94]

- August 30, 2004- Moisture from Hurricane Gaston drops moderate amounts of rainfall, leading to minor stream and drainage flooding.[97]
- September 3, 2004- The combination of swells from Hurricane Frances and a high pressure system causes rip currents along the Delaware coastline.[98]
- September 18, 2004- The remnants of Hurricane Ivan produce heavy rainfall for a few hours, causing creek flooding and drainage problems. Damage is minimal.[99]
- 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.[100] The remnants of Jeanne also spawn an F2 tornado in northern New Castle County. The tornado's 5 mile (8 km) path includes moving through the New Castle Airport and several buildings. The tornado damages numerous planes and buildings at the airport and injured five people. Damage totals to around $1 million (2004 USD).[101]
- 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.

- September 1, 2006- The combined effects of Tropical Storm Ernesto and a large high-pressure system leave about 151,000 without power and several trees damaged from strong winds. The system also drops moderate rainfall peaking at 5.15 inches (129 mm) in Jones Crossing; one person requires assistance to be rescued from a flooded roadway.[107]
- June 4, 2007- The remnants of Tropical Storm Barry drop light rainfall in the state.[48]
