List of Maryland hurricanes (1950–present)

Hurricane Isabel, one of the most significant storms to affect the region, on September 18, 2003

Since 1950, 93 known hurricanes, tropical storms and tropical depressions have affected the U.S. state of Maryland. Many of these storms also affect the country's capital, Washington, D.C., since the city is located on territory ceded by Maryland. Hurricanes are the most intense classification of these storms, while tropical storms and tropical depressions are generally weaker. The Delmarva Peninsula is often affected by cyclones that brush the East Coast.^[1] Central and Western Maryland, as well as Washington, D.C., commonly receive rainfall from the remnants of storms that make landfall elsewhere and track northward.^[2] On rare occasions, the area experiences the effects of Pacific storms; one such example of this is Hurricane Tico, which made landfall on Mexico and moved inland.

Hurricane Agnes of the 1972 season was the deadliest storm, killing 19 people as a result of heavy flooding. The most damaging storm was Hurricane Irene, which resulted in $151 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.^[3] No storms made landfall in Maryland at hurricane intensity. Since 1950, ten tropical cyclones have collectively killed 58 people

2005–2009

• July 8, 2005 – The extratropical remnants of Hurricane Cindy drop upwards of 7 in (180 mm) in the state,^[71] and spawn one tornado.^[72] which causes sporadic tree damage.^[73] The rainfall causes flooding in some locations, leaving numerous roads underwater,^[74] and flooding several basements.^[75]

2010-present

• September 3, 2010 – Hurricane Earl skimmed the coast of North Carolina and moved northeastward, resulting in heavy rain and tropical storm force winds in Southeastern Maryland, near Ocean City. Areas inland were not affected by Earl.
• August 27, 2011 – Hurricane Irene did not make direct landfall, but due to the large size, hurricane conditions were felt to the east of the Chesapeake Bay and tropical storm conditions were felt as far inland as Frederick, MD. Along the Delmarva Peninsula, sustained winds of 60 mph with gusts up to 85 mph and over a foot of rain fell over the area. There was also a five-foot storm surge that inundated regions around Ocean City, MD. The beach was evacuated prior to the storm; due to the minimal damage, it reopened the next day on Sunday and residents and tourists were allowed to return.^[83] In Central Maryland, sustained winds of 30-40 mph and 3-5 inches of rain fell. Gusts of up to 65 mph toppled many power lines. Most of the damage was from falling trees, which blocked roads, crushed power lines, and toppled onto houses. Power was out for over 200,000 people in Maryland; however, by Sunday, most power was restored.^[84]
• October 29, 2012 – Hurricane Sandy makes landfall north of the state. However, due to the tremendous size of the storm, its effects were felt all over Maryland. During the peak of the storm, 60 mph sustained winds were felt from Frederick, Maryland eastward. However, power outages were not widespread and any problems were solved quickly due to better preparation. Heavy rain affected the state, with up to a foot of rain falling in some spots. Storm surge was also a large factor along the beaches, washing out many piers and some boardwalks along Ocean City. Hurricane Sandy is the deadliest tropical cyclone to affect the state, causing 11 deaths.
