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.

It quickly powered up from a tropical storm to a Category 5 in a single day, the National Hurricane Center said.

Hurricane Erin rapidly exploded overnight from a Category 3 storm to a massive Category 5 and is expected to strengthen further as it curves north between the U.S. East Coast and Bermuda this upcoming week, according to the National Hurricane Center.
