Oscar, which the National Hurricane Center characterized as "very small," is the 15th named storm of the hurricane season.

Hurricane Oscar maintained Category 1 strength as the small hurricane made a second landfall in Cuba Sunday evening.

Hours earlier, Tropical Storm Nadine formed off Mexico's southern Caribbean coast and was moving inland across Belize.

Tropical Storm Oscar is making it harder to restore power in Cuba after a massive, prolonged power outage that preceded the storm. The nation’s power grid failed on Friday after Cuba’s largest power plant went offline,

Oscar probably won’t be around long. After making a run westward at Cuba, it will begin turning north into Monday and weakening into Tuesday.

Oscar was also the eighth named storm to form since Sept. 24, breaking a record for most named storm formations between Sept. 24 and Oct. 19.

Hurricane Oscar formed Saturday off the coast of the Bahamas, the National Hurricane Center in Miami said. It characterized the storm as “tiny.” The government of the Bahamas has issued a hurricane warning for the Turks and Caicos Islands and the southeastern Bahamas.

Millions of Cubans were enduring electricity blackouts as the government struggled to restore services. Hurricane Oscar, striking the east as a Category 1 storm, added to the disruption.

Hurricane Oscar made landfall on Great Inagua Island in the Bahamas and is forecast to strike in eastern Cuba on Sunday afternoon, the US National Hurricane Center said.
