Cuba's electrical grid collapsed Sunday for the fourth time in 48 hours, a major setback in the efforts to restore power to exhausted residents.

Cubans in the eastern provinces of Holguín and Guantánamo braced for a direct hit by Hurricane Oscar on Sunday afternoon. As the Category 1 hurricane made landfall near Baracoa, a coastal in city in Guantánamo province, around 5:50 p.m., most of the country still had no power.

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