Since 1950, 144 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 (120 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, thirteen tropical cyclones have collectively killed 64 people.
