Impact

Caribbean Sea

As a tropical depression, the storm moved rapidly through the Lesser Antilles; consequently, most islands only experienced minor effects. For example, Saint Lucia received light and sporadic rain showers, accompanied by sustained winds of 20–25 mph (32–40 km/h) and gusts to 35 mph (55 km/h). In

, however, the depression dropped up to 9.2 inches (235 mm) of rain in 24 hours. The rainfall blocked storm drains, including those near the airport, which was forced to shut down. The rainfall caused debris to collect on roads throughout the island. Although the storm passed just 70 miles (110 km) north of the Yucatán Peninsula, the storm dropped only 0.6 inches (15 mm) of rain due to its small size.

North America

In Florida, Bonnie produced up to 4.1 inches (104 mm) of rainfall in Pace, with peak wind gusts of 42 mph (68 km/h). Bonnie was accompanied by a storm surge; moderate wave action caused slight beach erosion. Rainfall and storm surge flooded roads, forcing the evacuation of 2,000 residents in Taylor County. The winds downed trees and caused scattered power outages. A
