The area of low pressure preceding the development of Bertha produced rough surf and rip currents along the Florida coastline. In Perdido Key State Recreation Area, two children were swimming in an unguarded area when they were swept away by the currents. Their grandfather attempted to rescue them, but drowned in the rough waters. Another family rescued the two children. The large circulation of Bertha produced light rainfall across Florida, with Pensacola and Destin reporting 2.75 inches. Extreme southern portions of Alabama received over 3 inches (75 mm) of rain from the storm, while western Dauphin Island reported over 5 inches (125 mm).
