The first area has been under the eyes of the National Hurricane Center for a few days as it emerged off Africa’s west coast.

Erin, a sprawling Category 2 hurricane, is not forecast to make landfall but will impact much of the East Coast with dangerous coastal conditions as it tracks north, nearly paralleling the coast. Bermuda will face similar conditions to the storm's east.
