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.

Tropical Storm Rafael is expected to strengthen into a hurricane before making landfall in Cuba Wednesday, according to the National Hurricane Center.

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. The U.S. National Hurricane Center said Rafael would see "steady or rapid intensification" before plowing across western Cuba with maximum predicted winds of up to 100 mph (160 kph) by Wednesday.
