Tropical Storm Chris set to become hurricane Monday, Beryl threatens Puerto Rico

Forecasters say the disorganized center of Tropical Storm Beryl is moving towards the west-northwest near 23 miles per hour (37 kilometres per hour) and on this track will approach the Lesser Antilles today, move cross the island chain tonight and near or south of the Virgin Islands and Puerto Rico on Monday.

Chris was upgraded from a tropical depression to a tropical storm on Sunday.

Tropical storm-force winds extend outward up to 45 miles from the centre but forecasters anticipate Beryl to gradually weaken during the next 36 hours.

Tropical storm warnings were in effect for Dominica and Guadeloupe. "Hence the tropical storm watch for Barbados has been discontinued", the Barbados Met Office said last this morning.

The same amount, two to three inches, was also expected to fall on the U.S. Virgin Islands and Puerto Rico, with up to five inches possible in some areas, through Tuesday.

The storm was sitting almost still off the SC coast on Sunday, about 160 miles south of Cape Hatteras.

But the National Weather Service said Beryl remained on track to move south of the U.S. Virgin Islands and across western Puerto Rico on Monday, potentially bringing 2 to 3 inches (5-8 cm) of rain and gusty winds to the U.S. territory still recovering from the devastation wrought previous year by Hurricane Maria.

While Chris is expected to become a hurricane, it will stay offshore and head to sea, according to the storm center.

The next hurricane advisory is scheduled for 5 p.m. Sunday.
