According to the National Hurricane Center, Bertha came ashore in St Bernard Parish, around 40 miles east of New Orleans, with maximum sustained winds of 45 mph (72 kmph). Tropical storm-force winds extended nearly 100 miles (160 km) from the storm's centre.
The system prompted tropical storm warnings across parts of Louisiana, Mississippi and Alabama, including New Orleans and Lake Pontchartrain. Beaches, parks, piers and some low-lying roads were closed as officials prepared for storm surge and flooding.
Forecasters said coastal areas of Louisiana and Alabama could experience storm surges of up to 3 feet (1 metre), while rainfall of 1-4 inches (3-10 cm) is expected, with isolated locations likely to receive higher amounts.
