Tropical Storm Oscar dumped heavy rain across eastern Cuba on Monday after making landfall as a Category 1 hurricane on the island already beleaguered by a massive power outage.
Its maximum sustained winds blew at 40 mph on Monday as Oscar moved northwest at 6 mph. The storm was located about 50 miles northwest of Guantánamo, Cuba, the U.S. National Hurricane Center in Miami said.
The storm made landfall as a Category 1 hurricane with maximum sustained winds of 75 mph in Guantanamo, near the city of Baracoa, on Sunday evening before weakening to a tropical storm.
The storm is expected to emerge off Cuba's northern coast late Monday and move near the southeastern and central Bahamas on Tuesday, forecasters said.
