Rain, tropical-storm-force winds and even the potential for some tornadoes are possible for some portions of Florida with Hurricane Rafael.

Tropical Storm Rafael is on track to hit the southern tip of Louisiana by Saturday as it continues to gather strength en route to the Gulf of Mexico, and could become a hurricane by the time it hits Cuba.

New storm models show the storm—which has a 90 percent chance of forming in the next seven days—could strike Florida's coast.

The National Hurricane Center said Wednesday it is tracking a system in the Caribbean that could soon strengthen into Hurricane Sara.

There is a strong consensus among the various computer forecast models that the tropical disturbance near Jamaica will organize into a tropical depression before the end of the week and pretty quickly develop into Tropical Storm Sara.
