SAN JUAN, Puerto Rico, Shawwal 5, 1435, Aug 1, 2014, SPA -- Tropical Storm Bertha approached the Caribbean on Friday as islands in the eastern region prepared for heavy rains and strong winds, AP reported. The storm's maximum sustained winds increased slightly Friday to 50 mph (85 kph), but no significant change in strength is expected in the next two days. Bertha was centered about 45 miles (70 kilometers) east of Martinique and was moving west-northwest at 22 mph (35 kph). The storm generated some rain and wind as it passed just north of Barbados on Friday, but no damage has been reported, said Judy Thomas, director of the island's emergency management agency. -- SPA 21:37 LOCAL TIME 18:37 GMT www.spa.gov.sa/w
