Hurricane Rafael brought strong winds, causing a shutdown of the country's electricity system for the second time in just weeks.

Hurricane Rafael blew through western Cuba on Wednesday night, flooding streets, damaging buildings and plunging millions of people into darkness. The country’s national power company, Unión Eléctrica, said that strong winds had caused the blackout.

The hurricane center cautioned there is "larger-than-normal uncertainty regarding Rafael's intensity later in the forecast period."
