Hurricane Erin, now a Category 2 hurricane, won't make landfall on the U.S. East Coast, but it will impact residents and visitors at North Carolina's Outer Banks.

Beachfront property owners braced for the worst amid predictions of a storm surge of up to 4 feet and significant coastal erosion. Powerful waves of 15 to 20 feet are expected to slam beaches, especially in North Carolina, for 48 hours or more as the hurricane crawls northward offshore through at least Thursday.

Hurricane Erin's path will keep its strongest winds offshore. However, this large storm will hammer the East Coast with coastal flooding and life-threatening rip currents through Friday. Here's the latest forecast.
