Hurricane Storm Risk Expands Beyond Traditional Coastal Hotspots
The nation’s largest concentration of hurricane-related property risk is no longer found along Florida’s beaches or Texas’ Gulf Coast. It is concentrated in and around New York City, where millions of homes and trillions of dollars in real estate value sit in the path of increasingly costly storms.
A new analysis released Tuesday by property intelligence firm Cotality found that more than 3.27 million homes across New York face moderate-to-severe hurricane wind exposure, representing nearly $1.93 trillion in potential reconstruction costs. The figure marks the highest concentration of hurricane-related residential exposure in the United States.
The findings underscore a growing reality confronting homeowners, insurers, and policymakers: hurricane risk is spreading far beyond the regions traditionally associated with tropical storms, while property values in vulnerable coastal markets continue to climb.
Nationally, more than 32 million homes now face moderate or greater hurricane wind risk, representing an estimated $12.26 trillion in reconstruction value, according to the report.
“Population growth, rising property values, and changing storm dynamics are creating unprecedented concentrations of risk,” said Maiclaire Bolton-Smith, vice president of insurance market insights at Cotality. “The geographic footprint of hurricane exposure is broader than many homeowners realize.”
The Northeast’s Growing Vulnerability
While Gulf Coast states experience more frequent hurricane landfalls, the Northeast’s dense population and high-value housing stock have elevated the region into one of the country’s most financially exposed areas.
New York ranked first nationally not only for hurricane wind exposure but also for storm surge vulnerability. More than 631,000 homes across the state face potential storm surge impacts, representing approximately $329 billion in reconstruction value.
The findings reflect lessons learned from major storms such as Hurricane Sandy, which struck the Northeast in 2012 and caused widespread flooding, infrastructure damage, and tens of billions of dollars in economic losses.
Industry analysts note that a single major hurricane making landfall near New York City could generate losses rivaling or exceeding some of the costliest natural disasters in U.S. history.
Houston ranked second nationally for hurricane wind exposure, with approximately 2.17 million at-risk homes representing roughly $824 billion in reconstruction value. Miami followed closely behind, with about 2.04 million homes exposed and an estimated $616 billion in property value at risk.
Florida and Texas Remain Ground Zero
Despite New York’s position atop the metropolitan rankings, Florida and Texas continue to represent the largest statewide concentrations of hurricane risk.
Florida leads the nation with approximately 8.25 million homes exposed to moderate or greater hurricane wind risk, accounting for more than $2.56 trillion in reconstruction costs. Texas ranks second with nearly 4.8 million vulnerable homes, followed by North Carolina with more than 3.1 million.
Storm surge exposure remains heavily concentrated in Florida as well. The state contains roughly 2.47 million homes vulnerable to surge-related flooding, representing nearly $748 billion in property value–more than three times the exposure found in Louisiana, the nation’s second-most vulnerable state for storm surge losses.
The findings arrive as insurers continue to reassess coastal risk models and homeowners in many hurricane-prone regions face rising insurance premiums, stricter underwriting standards, and shrinking coverage options.
The Insurance Gap Few Homeowners See
Perhaps the report’s most concerning finding involves what researchers describe as a growing “hidden flood risk” affecting nearly one million American homes.
Cotality identified approximately 927,000 properties facing significant hurricane-related flood exposure despite being located outside federally designated flood insurance requirement zones. Together, those homes represent roughly $405 billion in property value and are estimated to generate more than $1.7 billion in annual flood losses.
Because many homeowners outside mandatory flood zones do not carry flood insurance, these properties may be particularly vulnerable to catastrophic out-of-pocket losses following a major storm.
Louisiana emerged as one of the nation’s most concentrated areas of hidden flood exposure. Orleans Parish accounted for more than $41 billion in at-risk property value located outside mandatory flood insurance boundaries, followed by neighboring Jefferson Parish with approximately $29 billion.
Other counties ranking among the nation’s most exposed include Brevard County, Florida; Harris County, Texas; and Suffolk County, New York.
Beyond Traditional Flood Maps
The report highlights growing concerns among risk analysts that federal flood maps may not fully capture evolving threats from heavier rainfall, storm-driven flooding, and changing weather patterns.
Researchers increasingly rely on property-level elevation data, advanced flood modeling, and high-resolution geographic analysis to identify risks that may not appear within traditional floodplain boundaries.
“As storms produce more intense rainfall and impacts extend farther inland, understanding risk requires a more detailed view than conventional mapping alone can provide,” Bolton-Smith said.
For homeowners, the implications are significant. Properties located outside mandatory flood insurance zones may still face substantial financial exposure from hurricane-related flooding–often without adequate insurance protection.
As the 2026 Atlantic hurricane season begins, the report serves as a reminder that some of America’s greatest concentrations of storm risk are found not only along the Gulf Coast, but also within the densely populated urban corridors of the Northeast, where a single storm could expose trillions of dollars in residential real estate to damage.
