Hurricane Erin, after strengthening into a Category 5 storm early Saturday, weakened to Category 3 by Sunday morning and has taken a track slightly more south than originally forecast, the National Hurricane Center said.

Hurricane Erin is expected to steer clear of the U.S. East Coast, but its massive impacts could include rip currents on American beaches.

An eyewall replacement cycle is underway within Hurricane Erin as the monster storm continues to barrel across the Atlantic while bringing gusty winds and rain to Puerto Rico and the Virgin Islands after rapidly intensifying into a catastrophic Category 5 hurricane over the weekend.

Erin, the first hurricane of the season, is now forecast to become a Category 4 by Sunday. Here's where it could head in the week ahead.

Erin is the first hurricane to develop over the Atlantic this year, and meteorologists are closely tracking its path and forecast.
