Rafael made landfall in the Cuban province of Artemisa, just east of Playa Majana, the National Hurricane Center said in a 4:15 p.m. update. The storm is packing maximum sustained winds near 115 mph and is moving northwest at 14 mph.

The National Hurricane Center forecasts Tropical Storm Rafael to grow into the season’s 11th hurricane Tuesday as it moves toward Cuba with winds and storm surge expected to affect the Florida Keys this week.

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.
