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.

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.

Tropical Storm Erin is forecast to rapidly strengthen into a hurricane this weekend as it nears the northeastern Caribbean and Bahamas, raising concerns for strong winds, heavy rain, and dangerous surf along the islands.

A Royal Caribbean Vision of the Seas cruise from Baltimore to Bermuda will now head to Florida in order to avoid Tropical Storm Erin.

Hurricane Erin is remaining a rare Category 5 hurricane as it passes north of the Northern Leeward Islands. Erin is expected to continue to bring rain, gusty winds and high surf to parts of the Caribbean this weekend before pivoting northward and passing between Bermuda and the U.
