BEAUMONT, Texas — Tropical Storm Erin is moving quickly westward across the Atlantic Ocean and could strengthen into a hurricane by late Thursday, prompting the National Hurricane Center to advise residents of the northern Leeward Islands, Virgin Islands and Puerto Rico to monitor the storm's progress.

Hurricane Erin became a catastrophic Category 5 storm before noon on Saturday, Aug. 16, according to the latest advisory from the National Hurricane Center.

Erin is expected to produce dangerous surf and rip currents along the beaches of the Bahamas, much of the East Coast of the U.S., including Florida, and Atlantic Canada next week.
