A report this week from ABC News confirmed that Tropical Storm Bertha made landfall east of New Orleans, Louisiana, striking a corridor that includes St. Tammany and St. Bernard parishes — communities that have faced repeated tropical weather impacts since Katrina in 2005. The storm came ashore along the Gulf Coast, a stretch of Louisiana coastline that sits at one of the lowest elevations of any densely populated region in the continental United States.
The landfall point east of New Orleans places Bertha's track over the Lake Borgne basin and the marshlands of coastal St. Bernard Parish, an area with limited natural storm surge buffering due to decades of coastal land loss that Louisiana has been working to address through its Coastal Master Plan administered by the Coastal Protection and Restoration Authority (CPRA). The Louisiana Governor's Office of Homeland Security and Emergency Preparedness (GOHSEP) activated its response protocols ahead of the storm, coordinating with the Louisiana National Guard and parish emergency managers across the southeast Louisiana region.
Tropical storms making landfall in this specific geographic pocket — east of the city rather than directly over it — can funnel surge water into Lake Pontchartrain and the lower Ninth Ward drainage basin through a well-documented meteorological effect. The Southeast Louisiana Flood Protection Authority–East, which oversees the post-Katrina levee system, monitors water levels across this system in real time. Power outages in Entergy Louisiana's service territory, which covers the greater New Orleans metro, are a consistent secondary impact of Gulf landfalls in this zone.
For preparedness-minded households in Louisiana, the Bertha landfall is a reminder that the state's airshed and grid infrastructure share geography that makes cascading failures — storm surge compromising water treatment facilities, grid outages disabling sewage lift stations, and air quality degradation from flooding — a compounding rather than sequential risk. The Greater New Orleans area's drainage system, one of the most complex urban pump networks in the world operated by the Sewerage and Water Board of New Orleans, depends on continuous electrical power; tropical storm-force winds alone, without major surge, have historically been sufficient to strain that dependency.
