Tropical storm Erin is forecast to become the first major Atlantic hurricane of the year, and it could bring dangerous weather to the East. Here’s what to know. The first Atlantic hurricane of the year could be upon us.

The chances that the storm will make landfall in the U.S. have increased slightly after the path shifted south.

A southward shift in Erin’s track has led to an increase in risk for the northern Caribbean Islands, though a direct hit in the United States is unlikely.
