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.

Hurricane Erin was a Category 4 storm with 130 mph winds on Monday night as it passed to the east of the Bahamas. The forecast track keeps the center of the storm well away from the U.S. East Coast this week, but tropical storm and storm surge watches have been issued for the North Carolina Outer Banks.

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.
