HAVANA (Reuters) -Tropical Storm Rafael gained steam late on Monday as it churned northward toward Cuba, which is still struggling to recover from a nationwide blackout and hurricane two weeks ago.

Tropical Storm Rafael is expected to become a hurricane by the end of Wednesday. Rafael is expected to strengthen into a hurricane as it heads toward Cuba. “Rafael is expected to become a hurricane as it passes near the Cayman Islands with further strengthening before it makes landfall in Cuba,” according to the National Hurricane Center in Miami.

Hurricane Rafael is swirling past the Cayman Islands and is expected to rapidly intensify until making landfall in western Cuba, where it’s forecast to hit as a Category 2 hurricane.
