MIAMI - The lower and middle Florida Keys are under a tropical storm warning as Hurricane Rafael is forecast to grow steadily on a path for Cuba, where it's expected to arrive on Wednesday. A tropical storm warning is also issued for portions of Cuba. A hurricane warning is in effect for parts of Cuba.

Hurricane Rafael has strengthened into a major Category 3 storm as it impacts Cuba before moving into the Gulf of Mexico.

While seeing a storm track in November is alarming, the risks of damaging wind or surge on the remain quite low and enhanced rain chances should be Rafael's only impact on Florida.
