The Gulf Coast is bracing for flooding, strong winds, and storm surges as Tropical Storm Bertha approaches. Coastal areas in Louisiana, Mississippi, Alabama, and Florida are under tropical storm warnings, with potential flash flooding in urban areas due to heavy rainfall. Beaches have been closed, and double red flags signal dangerous swimming conditions. Louisiana could experience storm surges up to 4 feet, while Mississippi and Florida face smaller surges. Communities recovering from previous flooding caused by Tropical Storm Arthur may be particularly vulnerable. Authorities have set up sandbag distribution sites to mitigate flood risks.
