Additional strengthening is expected as the storm is forecast to “remain a large and dangerous major hurricane through the middle of this week,” the National Hurricane Center said.

Forecasters said Erin should begin to slowly weaken as it increased wind shear. However, it's predicted to remain a major hurricane until late next week.

"The core of Erin is expected to pass to the east of the southeastern and central Bahamas today and tonight," the National Hurricane Center said.

While the category 4 storm is not expected to make landfall on the U.S. east coast, it will have an impact nonetheless. Dangerous high surf and rip currents are expected from Florida to New England throughout the week.

The storm is expected to continue to fluctuate in intensity and could double or even triple in size as it moves north and west, reports said.
