Disaster history
Hurricane Sandy
Hurricane Sandy brought coastal flooding, power outages, transportation disruption, and building and healthcare impacts across a wide region. It became a major reference point for storm surge planning, evacuation communication, infrastructure resilience, and recovery policy.
What happened
Overview
Hurricane Sandy formed in the Caribbean in October 2012 and later moved toward the U.S. East Coast, where it transitioned into a large post-tropical cyclone near landfall. Its broad wind field and storm surge affected dense coastal communities, including parts of New York, New Jersey, Connecticut, and nearby states. Sandy disrupted power for millions, flooded streets and tunnels, closed transit systems, affected hospitals and high-rise buildings, and damaged homes and businesses. Evacuation and shelter decisions were complicated by timing, public understanding of risk zones, building type, mobility needs, pets, and the difficulty of leaving familiar places. The event became a major case study in communicating storm surge risk, protecting critical infrastructure, planning for long-duration power outages, and rebuilding in ways that account for future coastal flooding. For households, it is a reminder that hurricanes can affect cities, apartments, transit riders, healthcare access, and utilities, not only beach houses.
Timeline
Key moments
Sandy formed in the Caribbean and was monitored by the National Hurricane Center as it developed.
Sandy affected parts of the Caribbean before moving northward and drawing attention from forecasters along the U.S. East Coast.
Warnings, evacuation instructions, transit closures, and preparations expanded across parts of the Mid-Atlantic and Northeast.
Sandy made landfall near the New Jersey coast as a post-tropical cyclone, with major coastal flooding and widespread power outages.
Recovery included restoring power, reopening transportation, repairing buildings, supporting displaced residents, and reassessing coastal planning.
Why it mattered
- It showed that storm surge can produce severe impacts in dense urban and suburban areas.
- It revealed the vulnerability of underground transit, tunnels, basements, mechanical rooms, and coastal utilities.
- It highlighted the importance of understandable evacuation zones and risk communication.
- It stressed healthcare continuity, high-rise building services, backup power, and patient movement planning.
- It influenced later discussions about coastal resilience, rebuilding standards, and infrastructure protection.
Systems that were stressed
- Power distribution, substations, backup power, fuel access, and communications
- Subways, tunnels, roads, bridges, airports, ports, and commuter systems
- Hospitals, nursing facilities, clinics, pharmacies, and building life-safety systems
- Evacuation zones, shelters, pet support, accessible transportation, and public messaging
- Housing repair, temporary assistance, insurance processes, permits, and long-term recovery
Preparedness lessons
- Know your local hurricane evacuation zone and understand whether storm surge, not only wind, is part of your risk.
- Plan for power outages in apartments, high-rises, and homes by considering elevators, phones, medical devices, refrigeration, and lighting.
- Keep a basic emergency kit with documents, medications, chargers, food, water, and items for children, pets, or assistive needs.
- Have a plan for leaving early if local officials order evacuation, including options that do not assume access to a private car.
- Prepare calmly by taking one practical step, such as saving offline maps, emergency contacts, and local alert sources before storm season.
Community lessons
- Coastal cities need clear surge maps, plain-language evacuation messages, and accessible shelter options.
- Critical infrastructure should be assessed for flood exposure, backup power limits, and recovery time.
- Transit-dependent households need realistic evacuation and service-restoration information.
- Healthcare and residential buildings need plans for power loss, elevators, heat, water, medications, and safe movement.
- Recovery planning should include renters, public housing residents, small businesses, schools, and people with limited insurance or savings.
