Fishermen are watching the weather intently as Hurricane Erin's predicted big swell could throw a fork in their plans

Life-threatening waves and rip currents are expected along the East Coast this week, with Hatteras Island in the Outer Banks under an evacuation order.

Hurricane Erin won't make landfall in the U.S., but it will bring dangerous rip currents to the East Coast. Beachgoers from Florida to the Carolinas to the Mid-Atlantic to Long Island need to be on alert for rip currents from Erin this week. A rip current, which flows out toward the ocean, can quickly pull a swimmer away from the shore.

Though Hurricane Erin is not forecast to make landfall on the U.S., the storm’s rapid intensification has prompted increased measures in North Carolina.

Hurricane Erin was a Category 4 storm Monday morning and is expected to retain major hurricane status through the middle of the week.

Hurricane Erin is forecast to "substantially grow in size" as it moves across the western Atlantic, according to the National Hurricane Center.
