Hurricane tops the risk list, and FEMA has declared Maryland a disaster area 38 times since 1953. Here's what to prepare for — and how.
Maryland's disaster profile is shaped by its remarkable geographic diversity — from the Atlantic-facing Eastern Shore and Chesapeake Bay lowlands to the Appalachian ridges of the west. That variety means the state faces credible threats from hurricanes, flooding, and severe winter storms, all rated at medium risk, while tornadoes remain a lower but real concern. Flooding is the most frequently declared disaster type, driven by the Bay's tidal dynamics, slow-moving storm systems, and the state's dense network of rivers and streams. Hurricanes and tropical storms follow closely, with the Atlantic coast and Bay shoreline serving as natural funnels for storm surge and wind damage. Hurricane Isabel in 2003 caused catastrophic flooding across the Chesapeake region, inundating Annapolis and damaging thousands of homes. In 1996, Hurricane Fran delivered destructive flooding to western and central Maryland after tracking inland. More recently, Tropical Storm Isaias in 2020 — Maryland's most recent major federal disaster declaration — brought damaging winds and flash flooding that left hundreds of thousands without power. Winter storms are a recurring challenge as well; significant nor'easters have repeatedly disrupted the Baltimore-Washington corridor and isolated mountain communities. Maryland has received 31 major federal disaster declarations, a record that underscores how consistently residents face disruption from natural events. For those living here today, that history is a practical guide: flood insurance, reliable communication plans, and go-bags suited to both evacuation and shelter-in-place scenarios are not optional extras — they are baseline preparedness for a state that sits at the intersection of multiple hazard zones.
Hurricanes bring storm surge, wind damage, and flooding that can cut off evacuation routes.
Flooding is the most common US disaster — just 6 inches of moving water can knock a person down.
Extended winter storms knock out power for days — prepare to survive without heat.
Tornadoes can form within minutes and level a home — identify your safe room now.
This low-lying, coastal plain region is most vulnerable to hurricane storm surge, tidal flooding from Chesapeake Bay tributaries, and tropical storm rainfall.
Dense urban and suburban development increases flash flood risk from heavy rain events, and the region regularly experiences disruptive nor'easters and ice storms.
Surrounded by the Patuxent River and Chesapeake Bay, this peninsula faces elevated storm surge, riverine flooding, and wind damage during hurricane and tropical storm events.
The mountain counties of Garrett and Allegany face the state's harshest winter storms, with heavy snow and ice capable of isolating communities for days at a time.
Rapid suburban development has increased impervious surface area, making these counties especially susceptible to flash flooding during severe thunderstorms and slow-moving tropical systems.

The state's official emergency management agency — alerts, shelter info, and disaster assistance.
Maryland residents can receive official emergency alerts through the statewide Maryland Emergency Alert System (EAS), Wireless Emergency Alerts on their mobile devices, and by enrolling in their county's local notification system — all coordinated through MEMA at mema.maryland.gov.
What natural disasters is Maryland most at risk for?
Maryland faces its greatest risk from flooding, hurricanes and tropical storms, and severe winter storms — all rated medium risk statewide. Flooding is the most frequently declared disaster type, with 10 federal declarations tied to flood events. Tornadoes occur but carry a lower overall risk rating compared to the state's other primary hazards.
Does Maryland require residents to carry flood insurance?
Maryland does not universally mandate flood insurance, but residents in federally designated Special Flood Hazard Areas with federally backed mortgages are required to carry it. Given the state's extensive Chesapeake Bay coastline and river floodplains, experts strongly recommend flood insurance even for properties outside high-risk zones, as flooding can and does occur widely.
How does Maryland alert residents during emergencies?
Maryland uses the Maryland Emergency Alert System (EAS) alongside Wireless Emergency Alerts sent automatically to cell phones in affected areas. Residents can also register for county-level notification systems, which vary by jurisdiction, and should monitor the Maryland Emergency Management Agency and local county OES websites for official guidance during active events.
What should a Maryland household emergency kit include?
A Maryland kit should account for the state's varied hazards: at least 72 hours of water and food, medications, a battery or hand-crank weather radio for outages, copies of important documents, and flood-specific supplies such as waterproof storage bags. Mountain-area residents should add warm clothing and supplies for potential winter road closures lasting multiple days.
