Hurricane tops the risk list, and FEMA has declared New Jersey a disaster area 59 times since 1953. Here's what to prepare for — and how.
New Jersey's geography places it squarely in the path of some of the Atlantic seaboard's most punishing weather. Flanked by the Atlantic Ocean to the east and Delaware Bay to the south, the state funnels hurricane energy, coastal flooding, and nor'easter storms directly into densely populated communities. FEMA has issued 43 major disaster declarations for New Jersey, with severe storms and hurricanes accounting for the overwhelming majority of incidents. Hurricane Sandy in 2012 was the state's most catastrophic modern disaster, killing dozens of New Jersey residents, destroying or damaging hundreds of thousands of homes, and causing tens of billions of dollars in losses across the Shore, barrier islands, and even inland river corridors. A decade earlier, Hurricane Floyd in 1999 drove catastrophic inland flooding along the Raritan and Passaic rivers, displacing thousands and demonstrating that storm impacts reach far beyond the coastline. More recently, the remnants of Hurricane Ida in 2021 produced historic flash flooding that killed at least 27 New Jerseyans, many trapped in basement apartments, reinforcing that urban and suburban areas are acutely vulnerable to rapidly rising water. Flooding — coastal, riverine, and flash — is the thread running through nearly every major disaster in state history. For residents preparing today, that record demands flood insurance regardless of zone designation, a practiced evacuation plan, and emergency supplies sufficient for multiple days without power or road access. New Jersey's hazard history is not a series of rare exceptions; it is a recurring pattern that preparedness can interrupt.
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 coastal strip faces the highest risk from Atlantic hurricanes, storm surge, and coastal flooding, as demonstrated devastatingly during Hurricane Sandy in 2012.
Low-lying terrain along the Delaware Bay makes communities here especially susceptible to tidal flooding and hurricane-driven surge from the southwest.
Riverine flooding dominates this region, with major flood events tied to nearly every significant storm system that crosses the state.
The Passaic River basin is one of the most chronically flood-prone watersheds in the Northeast, and the Hudson River corridor also faces serious storm-surge exposure.
Higher elevations here bring the state's most significant winter storm and ice accumulation risk, along with occasional tornado activity.

The state's official emergency management agency — alerts, shelter info, and disaster assistance.
New Jersey residents can register for NJ Alert, the state's official emergency notification system, at ready.nj.gov to receive warnings by text, email, or phone call during disasters and severe weather events.
What natural disasters is New Jersey most at risk for?
New Jersey faces the highest risk from hurricanes and flooding, which together account for the vast majority of the state's 43 major federal disaster declarations. Coastal storm surge, riverine flooding, and flash flooding all pose serious threats. Winter storms present a medium risk statewide, while tornadoes occur but are comparatively rare.
Do I need flood insurance if I'm not in a high-risk flood zone?
Yes. Flooding from storms like Ida in 2021 and Floyd in 1999 caused severe damage in areas outside designated high-risk zones. Standard homeowners and renters insurance does not cover flood damage. FEMA's National Flood Insurance Program is available to most New Jersey property owners and renters regardless of zone designation.
How do I receive official emergency alerts in New Jersey?
New Jersey uses the NJ Alert system, managed by the Office of Emergency Management, to deliver warnings via text, email, and phone. Residents should also ensure Wireless Emergency Alerts are enabled on their mobile devices, which automatically receive geotargeted alerts from the National Weather Service during imminent threats.
What should a New Jersey emergency kit include given the state's hazard history?
Given frequent multi-day power outages from hurricanes and nor'easters, kits should include at least 72 hours of water and food, flashlights with extra batteries, a battery-powered or hand-crank radio, medications, important documents in waterproof storage, and a phone charger with backup battery. Residents in flood-prone areas should also keep go-bags ready for rapid evacuation.
