HAVANA (AP) — Hurricane Rafael made landfall in Cuba as a powerful Category 3 hurricane shortly after powerful winds knocked out the country’s power grid. Forecasters warn that Rafael could bring “life-threatening” storm surges, winds and flash floods to western swaths of the island, after knocking out power and dumping rain on the Cayman Islands and Jamaica. The storm is bad news for Cuba, which is struggling with devastating blackouts while recovering from another hurricane two weeks ago that killed at least six people in the eastern part of the island.
