The primary risks from Tropical Storm Bertha include strong winds, heavy rainfall, and storm surges. Coastal areas in Louisiana, Mississippi, and Florida are particularly vulnerable, with some regions still recovering from previous flooding caused by Tropical Storm Arthur. Parks, piers, and low-lying roads have been closed as a precaution, and double-red flag warnings have been issued to keep swimmers off beaches. The storm's impact could lead to localized flooding and hazardous conditions along the Gulf Coast.
