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.

Hurricane Erin, now a powerful Category 4 storm churning in the Caribbean, is not forecast to hit land, but it will bring large waves and dangerous rip currents to the U.S. East Coast.

Hurricane Erin briefly strengthened into a Category 5 storm. It is not expected to make a direct hit on the U.S. but will create dangerous surf.

Swells triggered by the storm will create rough ocean conditions across the eastern seaboard this week, forecasters say.

As of the National Hurricane Center’s 8 a.m. advisory, the center of Erin was located about 115 miles north-northeast of Grand Turk Island and 890 miles

Hurricane Erin was a Category 4 storm again Monday morning and is expected to grow even larger and stronger, according to the latest advisory from the National Hurricane Center. Although Erin is forecast to move north between the U.S. and Bermuda, life-threatening surf and rip currents are likely across the Atlantic coast from Florida to Canada.

Hurricane Erin has strengthened back into a Category 4 hurricane as of Monday morning. Over the weekend, Erin underwent a process called rapid intensification, causing it to go from a category 1 hurricane to a category 5 hurricane within a roughly 24 hours.

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.
