List of Maryland hurricanes (1950–79)
Between 1950 and 1979, approximately 29 recorded tropical cyclones have significantly affected the U.S. state of Maryland. The Delmarva Peninsula is often affected by cyclones that brush the East Coast, while central and western Maryland commonly receive rainfall from the remnants of storms that make landfall elsewhere and track northward. Hurricanes are the most intense classification of tropical cyclones; tropical storms and tropical depressions are generally weaker.
Hurricane Agnes of the 1972 season was the deadliest storm, killing 19 people as a result of heavy flooding. Agnes was also the costliest storm, leaving about $80 million in damage. Hurricane Hazel caused sustained hurricane-force winds (winds of 75 mph (121 km/h) or greater) in the state, the only storm during the time period to do so. No storms made landfall in Maryland at hurricane intensity. Between 1950 and 1979, tropical cyclones have collectively killed approximately 40 people and inflicted over $93 million in damage.
- September 9, 1950 – Outer moisture from Hurricane Dog drops heavy rainfall in the Mid-Atlantic. In Bel Air, a car drove into the swollen Gunpowder River; three people in the car drowned and a fourth was injured.
- September 1, 1952 – Tropical Storm Able crosses the state, although damage, if any, is unknown.
- October 15, 1954 – Hurricane Hazel crosses the state, producing hurricane-force winds. In addition to wind damage, flooding was severe along the Chesapeake Bay, while flash flooding was reported inland. Overall, six deaths and about $11 million in damage were reported.
- August 12, 1955 – Tropical Storm Connie makes landfall in southern Maryland, dropping heavy rainfall peaking at 12.32 in (313 mm) in Preston. The rainfall leads to flooding which causes $2.5 million in damage. When the schooner Levin J. Marvel capsizes in high seas, 14 people drown.
- August 18, 1955 – As Tropical Storm Diane begins its turn to the east-northeast over Virginia, associated heavy rains, combined with saturated grounds from Connie just days before, cause flooding in central parts of the state, especially along the Potomac River.
- September 19, 1955 – Hurricane Ione makes landfall in North Carolina; its outer moisture produces light rainfall across the state.
- September 28, 1956 – Hurricane Flossy passes southeast of the state, producing up to 3.30 in (84 mm) of rain. In nearby Washington, D.C., a peak wind gust of 45 mph (72 km/h) is reported.
- September 28, 1958 – Hurricane Helene remains well off of the Carolina coast, though light rain falls across the Mid-Atlantic states.
- September 30, 1959 – The remnants of Hurricane Gracie drop moderate rainfall over western Maryland.
- July 30, 1960 – Tropical Storm Brenda crosses southeastern Maryland. The storm's rainfall causes flooding in St. Mary's County.
- September 12, 1960 – Hurricane Donna passes just offshore, producing wind gusts of over 100 mph (160 km/h) in Ocean City. Flooding along the eastern shore causes two deaths.
- September 21, 1961 – Hurricane Esther moves northward, parallel to the coast. Wind gusts to 45 mph (70 km/h) are observed at Ocean City, and storm surge flooding causes damage to the city's sea wall and boardwalk.
- September 1, 1964 – In Westernport, 5.80 in (147 mm) of rain falls as Tropical Storm Cleo tracks just south of the state.
- October 4, 1964 – The remnants of Hurricane Hilda cause light to moderate precipitation.
- October 17, 1964 – The remnants of Hurricane Isbell drop light rainfall.
- September 13, 1965 – The remnants of Hurricane Betsy produce light rainfall across western part of the state.
- September 16, 1967 – Tropical Storm Doria makes landfall in Virginia; associated high seas damage the boardwalk at Ocean City.
- June 13, 1968 – Tropical Depression Abby produces 3.83 in (97 mm) of rainfall at Centreville.
- June 26, 1968 – The remnants of Tropical Storm Candy drop moderate rainfall.
- September 11, 1968 – Tropical Depression Fourteen produces 4.68 in (119 mm) of rain near Parkton.
- October 20, 1968 – As Hurricane Gladys parallels the east coast, tides of up to 4 ft (1.2 m) are felt along the coast. As a result, street flooding is reported in Ocean City.
- August 20, 1969 – The remnants of Hurricane Camille cause extensive flooding in Virginia, though they drop only moderate rainfall peaking at 6.55 in (166 mm) in Maryland.
- September 9, 1969 – Hurricane Gerda intensifies offshore, prompting a hurricane watch for eastern Maryland. Because the storm remained offshore, only light precipitation falls.
- August 28, 1971 – Tropical Storm Doria parallels the east coast, resulting in tides 2.7 feet (0.8 m) above normal in Fort Henry.
- September 13, 1971 – Tropical Storm Heidi passes offshore, dropping 2.86 in (73 mm) of rain in parts of the state.
- Early October, 1971 – The remnants of Hurricane Ginger make landfall in North Carolina, turn north-northeast, and brush southern Maryland with light rainfall.
- June 2, 1972 – Heavy rainfall from Tropical Storm Agnes, combined with a separate low to the west, contribute to the state's worst flooding in 36 years. Severe damage and at least 19 deaths are reported throughout the region. Throughout the state, 1,930 were damaged, of which 103 were destroyed. 17 farm buildings were destroyed and 44 damaged, and 82 small businesses were destroyed. Total damage is estimated at $80 million.
- September 3, 1972 – Tropical Storm Carrie remains well offshore, though its outer bands drop light precipitation across the southern Delmarva Peninsula.
- September 23 – September 26, 1975 – Hurricane Eloise becomes an extratropical frontal low over Virginia. The storm's moisture drops 14.23 in (361 mm) of rain in Westminster, causing severe flooding, particularly in the Monocacy and Patapsco River basins.
- October 27, 1975 – Tropical Storm Hallie becomes extratropical to the east of the state; light rain falls over the southern Delmarva Peninsula.
- August 9, 1976 – Hurricane Belle parallels the east coast, prompting hurricane warnings for the coastline. The center of the storm passes to the east of the state, producing wind gusts of around 70 mph (110 km/h) at Ocean City.
- Mid-September 1976 – Subtropical Storm Three becomes extratropical to the south of the state. The resulting low moves northward, dropping moderate rainfall.
- July 29 – July 31, 1979 – The remnants of Tropical Storm Claudette drop light, spotty rainfall in southern areas.
- September 5, 1979 – Tropical Storm David crosses the western part of the state, dropping up to 9.40 in (239 mm) of rainfall. Associated bands spawn seven tornadoes throughout the state. One of the tornadoes strikes near Crofton, causing tree and structure damage, as well as one injury.
