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.

Although the storm is expected to stay offshore, it will produce dangerous surf conditions for much of the Atlantic Coast this week, forecasters say.

Erin continues to grow in size, and its impacts from high surf, rip currents and coastal flooding are already increasing along parts of the East Coast. Here's the latest forecast.
