Hurricane Erin is a huge Category 4 storm and is expected to both grow larger and stronger today as it moves toward the west-northwest. The center of the storm is expected to remain offshore as it moves between the U.S. and Bermuda.

Erin isn't as intense as it once was. But its large size is what matters most. While it won't landfall, it will bring high surf and rip currents to much of the East Coast. And it could bring damaging surge flooding for some.

Much of North Carolina’s Outer Banks region is under a tropical storm watch with Hurricane Erin expected to skirt the area Wednesday through Thursday, according to the National Hurricane Center.
