Erin, which quickly strengthened into a Category 5 storm on Saturday, is not expected to make landfall in the U.S., but experts remain on alert.

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 could 'at least double or triple in size' next week and the track has shifted south, but remains likely to turn away from the East Coast.

Tropical Storm Erin continues its westward path across the Atlantic, expected to become a hurricane Aug. 15, and a major hurricane by Sunday morning.
