Erin is the fifth named storm to develop during the Atlantic hurricane season, which started just over two months ago. Last week, Tropical Storm Dexter formed in the western Atlantic but didn't pose a threat to land. In early July, Tropical Storm Chantal made landfall on the Carolina coast, bringing deadly flooding to the region.

Hurricane Erin is expected to grow as it moves over the Atlantic through the week, causing dangerous rip currents, heavy rain, and strong winds along the East Coast.
