Tropical Storm Sandy headed for Jamaica, then Cuba

MIAMI - Tropical Storm Sandy was expected to become a hurricane on Wednesday as it approaches the south coast of Jamaica, the US National Hurricane Center said, prompting authorities on the Caribbean island to close schools and prepare shelters to take in residents of flood prone areas.
The storm was centered about 260 miles (420 km) south-southwest of the Jamaican capital, Kingston, on Tuesday evening and had top sustained winds of 50 miles per hour (85 kph).
Forecasters said a tropical storm watch might be issued for South Florida on Tuesday night or Wednesday morning, but the storm did not pose a threat to the Gulf of Mexico, where US oil and gas operations are clustered.
