Oscar, a Category 1 hurricane with maximum sustained winds of 80 mph, was approaching Cuba after making landfall in the Bahamas hours earlier.

Cuba had three electric grid collapses since Friday, and most of the country remains in the dark as slow progress is made to restore power.

The center in Miami said the storm’s center arrived in the Cuban province of Guantanamo, near the city of Baracoa, on Sunday evening. Its maximum sustained winds were near 80 mph.
