Hurricane Erin has weakened slightly. Meanwhile, the National Hurricane Center is monitoring two other potential developments in the Atlantic.

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 weakened to a Category 3 storm with maximum sustained winds of 125 mph while its outer bands pounded the Virgin Islands and Puerto Rico with gusty winds and heavy rains early Sunday.

Invest 98L could become a short-lived tropical depression before moving inland over northeastern Mexico or southern Texas later today. The National Hurricane Center is tracking two systems in the Atlantic basin, according to the latest advisory from the National Hurricane Center.
