Officials in the northern Caribbean are warning of heavy rains and dangerous swells as Tropical Storm Erin approaches the region.

While the most likely track keeps Erin offshore from the U.S. East Coast, shifts in the storm’s path could bring strong winds, heavy rain, and coastal flooding to parts of the eastern United States and Bermuda.

Erin has strengthened into a hurricane as it approaches Puerto Rico and the Virgin Islands, bringing heavy rains that could cause flooding and landslides.
