Interests elsewhere in the northern Leeward Islands, Virgin Islands, and Puerto Rico, as well as in the Turks and Caicos and the southeastern Bahamas should monitor the progress of Erin.

Hazards affecting land

Rainfall. The outer bands of Erin are expected to continue producing areas of heavy rainfall through Sunday across the northern Leeward Islands, the Virgin Islands, and Puerto Rico. Rainfall totals of 2 to 4 inches, with isolated totals of 6 inches, are expected. Locally considerable flash and urban flooding, along with landslides or mudslides, are possible.

For a complete forecast of rainfall and flash flooding associated with Erin, please see the National Weather Service Storm Total Rainfall Graphic, available at hurricanes.gov/graphics_at5.shtml?rainqpf

Wind. Tropical storm conditions are possible within the watch area today.

Surf. Swells generated by Erin will affect portions of the northern Leeward Islands, the Virgin Islands, Puerto Rico, Hispaniola, and the Turks and Caicos Islands through the weekend. These swells will spread to the Bahamas, Bermuda, and the east coast of the United States early next week. These rough ocean conditions will likely cause life-threatening surf and rip currents.
