Tropical storms and hurricanes are a regular part of weather in the D.C. region and the broader Mid-Atlantic. While the area rarely takes a direct hit from a powerful hurricane, remnants of tropical systems frequently move inland, bringing heavy rain, flooding and occasionally damaging winds. In some years, multiple systems affect the region.
Some of the region’s most memorable weather disasters have come from tropical systems. Hurricane Agnes in 1972 triggered catastrophic flooding across the Mid-Atlantic, while Hurricane Isabel in 2003 sent a powerful storm surge up the Chesapeake Bay and Potomac River, flooding parts of D.C. and the surrounding region. These events serve as reminders that even storms that weaken before reaching the area can still have major impacts.
Mid-Atlantic tropical systems or remnants by year
The broader Mid-Atlantic typically experiences one to two tropical systems — usually their remnants — each year. When atmospheric patterns steer at least one storm into the region, they often linger, allowing multiple systems to affect the area in the same season.
Other storms not shown on the map above, because their cores pass too far away, have still influenced the region indirectly by sending surges of tropical moisture northward. Such remnants play a major role in summer and fall rainfall and occasionally help trigger severe thunderstorms and tornadoes.
The most active modern year for tropical systems in the region was 2004, when the remnants of Charley, Frances, Gaston, Jeanne and Ivan all moved through or near the Mid-Atlantic.
The most common months
About 35 percent of storms affecting the Mid-Atlantic occur in September, making it the most common month for tropical systems to reach the region. August ranks second, while June, July and October occur at roughly similar — and lower — frequencies.
This timing aligns closely with the overall Atlantic hurricane season, which typically peaks in early to mid-September.
D.C.'s most memorable hurricanes and tropical storms
Hurricane of 1878 (October): Historical reconstructions by the National Oceanic and Atmospheric Administration indicate the storm likely made landfall in eastern North Carolina before moving northward. Also known as the Gale of ’78, it is archived as a Category 1 hurricane north of D.C. on Oct. 23 after passing over the city.
Hurricane of 1893 (October): The storm produced a 4- to 6-foot tidal surge on the Potomac and Anacostia rivers. A bridge over the latter was overtopped. Major flooding occurred in Alexandria and D.C., including numerous wharves destroyed and boats capsized. An associate justice of the Supreme Court was injured when a window at his home blew out.
Hurricane of 1896 (September): Newspaper reports described it as one of the worst storms ever recalled. It caused severe damage across parts of the area, including D.C. itself, where losses were estimated at at least $250,000, according to the Smithsonian Institution, and the Castle sustained significant damage. Across the Mid-Atlantic, buildings were destroyed and dozens were killed.
Chesapeake-Potomac (August 1933): After making landfall in southeast Virginia, the storm moved northwest toward the D.C. area. According to the National Weather Service, the storm’s eye passed just west of Washington, allowing powerful winds to push water up the Chesapeake Bay and Potomac River. It caused record high tides and storm surge of up to 11 feet in the city. Rainfall of 8 to 12 inches or more occurred east of the track in D.C., Maryland and toward the coast.
Hazel (October 1954): Hurricane Hazel made landfall in North Carolina as a Category 4 storm. It was already post-tropical when it reached D.C. but still produced the strongest wind ever officially observed in the city, with a 98 mph gust at National Airport. Wind damage was widespread, including toppled trees, blown-out windows and roof damage, with an estimate of $40 million in damage across the region. Three people died in Washington, in addition to 19 in surrounding states.
Connie and Diane (August 1955): Hurricanes Connie and Diane arrived within days of each other. Both brought heavy rainfall, and flooding was a major issue across the region. More than 10 inches of rain fell from the two storms in D.C. Rock Creek, the Potomac and the Anacostia all flooded. The pair also caused catastrophic flooding further northeast in places such as Connecticut.
Agnes (June 1972): At the time, Agnes became the costliest storm to hit the United States. The Weather Service logged reports of 10 to 14 inches of rain. In Fairfax County, the Lake Barcroft Dam collapsed under the strain of floodwaters, killing five firefighters attempting rescues. The Potomac River at Wisconsin Avenue rose 15.5 feet, its third-worst flood. Dozens of people died in the broader region, including two in a raging Rock Creek. Parts of the National Zoo were also left under water.
Floyd (September 1999): Skirting the Atlantic coast just inland, Floyd knocked out power to hundreds of thousands in the D.C. region and left some in the dark for a week. It dropped as much as a foot or more of rain east of D.C. in Maryland. Widespread wind gusts of 50 to 70 mph, including 56 mph in the city, toppled trees and caused other damage. More than $100 million in damage occurred in Virginia alone.
Isabel (September 2003): Hurricane Isabel was one of the worst storms in the D.C. area on record. After making landfall in North Carolina, it raced northwest toward western Maryland. More than 1 million people lost power across the region. Storm surge on the Chesapeake Bay reached as high as 8 feet. Places such as Annapolis witnessed historic flooding, as did parts of Baltimore, where water levels exceeded those of the 1933 hurricane. Unusually strong southeast winds gusted to 80-plus mph, toppling trees across the area.
Ivan (September 2004): The largest tornado outbreak in Virginia state history occurred with Ivan’s swirling remnant low-pressure area as it pushed northward after landfall the previous day along the Gulf Coast. Most of the Mid-Atlantic tornadoes occurred in parts of the D.C. area’s western suburbs and in areas to the south and west. The storm center ended up passing just south of the city before making a large loop back toward the Gulf of Mexico.
Sandy (October 2012): Hurricane Sandy caused catastrophic damage, largely from storm-surge flooding, to areas northeast of the region, including around New York City. Initial uncertainty about the storm’s track and impacts led to two days of federal government closure in the city. Heavy rain dropped about 6 to 10 inches, and some flooding occurred, along with tree falls from wind gusts up to 60 mph. Much of the Mid-Atlantic through southern New York and Connecticut witnessed October low pressure records from the storm, with parts of Md., Pa., N.J. and Del. setting all-time records.
