Miami, Florida (CNN) -- Tomas continued to lose brawn in the Caribbean Sea on Monday morning after pummeling the island of St. Vincent over the weekend, the National Hurricane Center said. As of 5 a.m. ET Sunday, Tomas, a tropical storm with sustained winds of 50 mph (85 kph),  was located about 135 miles (220 kilometers) northeast of Curacao, according to the Hurricane Center. The storm was moving west at about 14 mph (22 kph). Tropical storm-force winds extended outward up to 175 miles (280 kilometers) from the center of Tomas. Tomas moved over the Caribbean Sea after leaving heavy rain and wind on St. Vincent. More than 1,000 people entered shelters on St. Vincent as Tomas struck the island, an emergency official said. Two people were injured, including one critically, when they tried to repair roof damage during the storm, said Michelle Forbes, acting director of National Emergency Management.
