The U.S National Hurricane Center (NHC) said on Friday that tropical storm Elsa had strengthened a little and was very close to the Lesser Antilles. Elsa is located about 70 miles (110 km) east-southeast of Barbados, with maximum sustained winds of 60 miles per hour (95 km/h), the NHC said, adding that by Sunday, Elsa is forecast to move near to Jamaica and parts of eastern Cuba, Reuters reported.
