St. Tammany Parish on the north shore of Lake Pontchartrain is one of Louisiana's fastest-growing parishes and faces serious hurricane risk. Ida caused widespread tree damage and power outages across the parish in 2021. The parish's location north of the lake means it receives storm surge from the north as hurricanes push lake water toward the Mandeville and Slidell shoreline.
