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.

Tropical Storm Oscar is moving across eastern Cuba after making landfall as a Category 1 hurricane on the island already beleaguered by a massive power outage.

Tropical Storm Oscar remained crouched over eastern Cuba, where it could drop more than a foot of rain as it crawls over the island nation at 3 mph. Oscar was a tiny, weak storm, with tropical-storm-force winds extending just 45 miles from the center and maximum sustained winds at 40 mph.
