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.

The National Hurricane Center is tracking two systems in the Atlantic basin, including Invest 98L, which could become a tropical depression before moving onshore in either Mexico or southern Texas.

Hurricane Erin will make its closest approach to the United States on Wednesday and Thursday, bringing dangerous surf and/or coastal flooding to a dozen states.
