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.

While a Gulf disturbance that moved into Texas on Friday seems to have run its course, Hurricane Erin in the western Atlantic intensifies.

Hurricane Erin strengthened into a powerful Category 4 storm Saturday in the Caribbean , where it threatened to dump flooding rains as it continued to grow larger and stronger, the National Hurricane Center said.
