A sweeping new map that plots every U.S. hurricane landfall since 1851 makes one thing painfully clear: southeast Louisiana is the most frequently hit stretch of coastline in the country. Dense clusters of landfalls stack up around the Mississippi River delta and neighboring parishes, underscoring why New Orleans and surrounding bayou communities live with such relentless risk. The project takes more than a century and a half of storm history and condenses it into one stark snapshot of regional vulnerability.
Hurricane researcher Michael Ferragamo compiled more than 170 years of storm data, tracking 307 U.S. hurricane landfalls, and told WWLTV that "you've got hurricanes that can come in from three different angles," referring to the multiple paths storms can take into the Gulf and over the delta. Ferragamo said he built the map to better communicate long-term risk, not just to drop a sea of random dots, and his work lights up a clear hotspot along the lower Mississippi. The pattern matches the official landfall record that stretches back more than 150 years.
Coastline Shape, Shelf And Steering Currents
The hotspot is not a fluke of cartography. NOAA's historical landfall records, which run back to 1851, already show heavy clustering along the northern Gulf. Coastal modeling has long flagged the Mississippi River delta's hooked coastline, its shallow continental shelf and its broad fetch as ingredients that boost surge and overall exposure. That broad fetch and curved shoreline make it more likely that storms passing nearby will run into land here instead of slipping past straighter stretches of coast. These coastal features, combined with prevailing steering currents, help explain why storms can bear down on southeast Louisiana from several directions, according to archived modeling by NOAA/USACE researchers.
Parish Counts Underscore The Hotspot
Ferragamo's parish-by-parish breakdown, compiled for local audiences, shows Lafourche Parish at the top with 41 recorded hurricane strikes. Next up are Terrebonne with 38, Plaquemines with 33, St. Bernard with 29 and Orleans Parish with 21. St. Mary and St. Tammany also log notably high tallies, and across the state line, Mississippi counties such as Hancock and Harrison show a history of repeated blows too. Those counts, pulled from the long-running HURDAT record and mapped by Ferragamo, were detailed in local coverage of the project by WWLTV.
What It Means For Residents And Officials
That long trail of clustered landfalls is more than trivia. Levee design, marsh restoration plans and evacuation playbooks all depend on where storms have historically come ashore. The Atlantic hurricane season runs from June 1 through November 30, and the National Hurricane Center and local emergency officials regularly emphasize preparedness as the season kicks off. Recent local reporting shows state and parish agencies already adjusting evacuation routes and expanding home-hardening programs ahead of the peak months; see NOAA/NHC and coverage of how Louisiana lines up escape routes for details.
Ferragamo's map is not a forecast. It is a distilled history that shows more than 170 years of landfall data converging on the same vulnerable stretch of southeast Louisiana coast, a history that planners argue should shape how and where the region builds and prepares. For residents in the New Orleans metro and the bayou parishes, the takeaway is blunt: this piece of shoreline has been in the bull's-eye many times before, and the record suggests it will be there again.
