Erin, the first hurricane of the season, exploded to a Category 5 hurricane Saturday, and despite fluctuations in intensity, the storm is remaining formidable this weekend. Here's where it could head in the week ahead.

Hurricane Erin rapidly exploded from a Category 3 storm to a massive Category 5 overnight and is on track to curve north between the U.S. East Coast and Bermuda next week, according to the National Hurricane Center.

Tropical Storm Erin has begun strengthening as it streaks west across the Atlantic and is on track to reach hurricane status as soon as Friday, prompting tropical storm watches in the northern Leeward Islands.
