MIAMI—Tropical Storm Imelda formed Sunday and is expected to become a hurricane on a forecast track curving away from the U.S. East Coast early this week. The storm dumped rain and churned up seas near the Bahamas and Cuba and even briefly prompted a tropical storm watch on a stretch of Florida’s Atlantic coast.
Meanwhile, Hurricane Humberto weakened slightly but remained a powerful Category 4 storm further out in the Atlantic, potentially threatening Bermuda. The Bermuda Weather Service issued a tropical storm watch, meaning tropical storm conditions were possible on the island within 48 hours.
