Tropical Storm Erin -- which is forecast to strengthen into the first hurricane of the Atlantic season by Saturday morning -- won't have a direct impact on the U.S., but it will bring dangerous rip currents to the East Coast.

Hurricane Hunters have filmed themselves flying through the eye of Hurricane Erin.

The storm’s rapid intensification has prompted increased emergency measures in North Carolina, and the Outer Banks — a popular summer vacation spot — are now under a state of emergency.
