Hurricane Oscar made landfall on Great Inagua Island in the Bahamas and is forecast to strike in eastern Cuba on Sunday afternoon, the US National Hurricane Center said.

Tropical Storm Oscar formed on Saturday, the 15th named storm of this year’s Atlantic hurricane season and the second in less than a day. It’s expected to bring heavy rain to the Caribbean islands this weekend, including Cuba, which has been facing a nationwide electricity crisis.

Tropical Storm Oscar has been upgraded to a hurricane just hours after forming near Turks and Caicos Islands Saturday morning, according to the National Hurricane Center. >> Video above: Lastest on the tropics Hurricane warnings are now in effect for the Turks and Caicos Islands and the Southeast Bahamas.
