The Caribbean islands are bracing for impact as Tropical Storm Dorian moves their way.

The storm now has 60 mph winds and is likely to become a hurricane over the next 24 hours.

A tropical storm warning is in effect for Barbados, St. Lucia, St. Vincent and the Grenadines. A tropical storm watch was issued for Grenada and Martinique.

Forecasters say Puerto Rico, the Dominican Republic, Haiti and the Virgin Islands should monitor Dorian's progress.

In Puerto Rico, video and pictures shared on Twitter showed people lined up for hours on Sunday to stock up on water and supplies ahead of the storm.

Dorian, the fourth tropical storm of the Atlantic hurricane season, became a named storm on Saturday. It is expected to be upgraded to a hurricane by Wednesday.
