Increased surf and dangerous rip currents are expected to continue along the eastern seaboard as Hurricane Erin moves into the North Atlantic.

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

Erin’s surf and storm surge could cause erosion along sections of the Florida and East Coast and shapes up as potentially worse for North Carolina’s barrier islands, which are under mandatory evacuation orders ahead of the four feet of storm surge and 20-foot offshore waves Erin is expected to bring.
