Hurricane Ida made landfall in Houma, Louisiana as a Category 4 (150 mph winds) — tying the record for the strongest landfalling Louisiana hurricane. It struck on the 16th anniversary of Katrina. New Orleans' post-Katrina levee system held, but communities outside the levee protection (Houma, Thibodaux, Grand Isle) were devastated. Ida then tracked northeast as a tropical remnant and unleashed 6–10 inches in 3 hours across New Jersey, New York, and Pennsylvania — a rate so extreme it overwhelmed storm drains and flooded basements across the entire Northeast urban corridor. NYC subway stations flooded and 13 people drowned in basement apartments in Queens and Brooklyn.
Rainfall Record
16.56 inches in Galliano, LA; catastrophic flooding from remnants across the Northeast (6–10 inches in 3 hours in NYC and NJ)
States
Primary Cities
Ida flooded 13 people to death in NYC basement apartments — 1,000 miles from landfall. No hurricane is a 'Gulf Coast problem'
Queens and Brooklyn basement flooding from Ida demonstrated that urban storm drain systems are designed for 1–2 inch/hour events, not 3–4 inch/hour extreme rainfall
Louisiana's post-Katrina levee improvements worked for New Orleans — but 60% of Louisiana's population lives outside the levee protection system
Homeowners insurance in PA, NJ, NY covers Ida rain damage — but many Northeast residents don't realize they're vulnerable to hurricane remnants
