Tropical Storm Bertha brings up to 4‑foot storm surge to Louisiana and Mississippi coasts

Coastal officials warned Thursday that storm surges as high as four feet could affect sections of the Louisiana and Mississippi shorelines later this week. The advisory, issued by the National Weather Service in coordination with state emergency management agencies, cites an approaching low‑pressure system expected to intensify as it moves inland, bringing strong onshore winds and elevated tide levels. Residents in vulnerable low‑lying areas were instructed to monitor local forecasts, secure property, and be prepared for possible mandatory evacuations if conditions worsen.

Authorities emphasized that the surge risk is confined to specific stretches of the Gulf Coast where the topography and tide cycles amplify wave height. Emergency shelters have been pre‑positioned, and local police and the Coast Guard are on standby to assist with rescues and traffic control. The warning will remain in effect until the system moves offshore, after which officials will reassess and update the public on any residual flooding threats.
