Hurricane forecasters continued to track a tropical wave off the coast of Africa Sunday morning as Hurricane Erin weakened to a Category 3 storm following an eyewall replacement cycle.

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.

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.
