The hurricane produced light rainfall and winds throughout the northern Lesser Antilles. The passage of Erika brought a cloud of ash to Antigua from the eruption of the Soufrière Hills Volcano on Montserrat, a rare occurrence. Strong waves from the hurricane produced beach erosion and coastal flooding in northern Puerto Rico, and killed two surfers. Moderate wind gusts in Puerto Rico left thousands without power, and the hurricane resulted in $10 million in damage to the Caribbean territory of the United States. Erika also produced gusty winds and light rain in the Azores. Later in its duration, the storm brought hurricane-force wind gusts and rainfall to the Azores, though no damage was reported. Erika was the only tropical cyclone in the Atlantic basin in the month of September in this year, the first such occurrence in a hurricane season since 1929.
