Cuba made fast progress restoring power to swaths of the Caribbean island nation on Tuesday, both in Havana and outlying provinces, even as emergency and grid workers struggled to reach areas ravaged by Tropical Storm Oscar.

Tropical Storm Oscar chugged toward the Bahamas on Tuesday after making landfall in Cuba as a Category 1 hurricane, killing at least six people as it unleashed heavy rains on an island also hit by an unrelated massive power outage.

The hurricane center said Oscar is expected to maintain tropical storm strength as it exits Cuba later Monday night. Its next stop, according to the latest forecast, is the southern and eastern Bahamas on Tuesday. It could strengthen a bit, forecasters said, but it’s still expected to be a tropical storm when it strikes.
