In a worst-case scenario for the U.S., a major hurricane could hit Florida's Gulf coast, but forecasters say it would have to clear several hurdles.

Tropical Storm Sara formed Thursday afternoon in the western Caribbean and is headed toward Honduras. Forecasters advised Florida residents to keep an eye on its track.

A newly formed Tropical Storm in the Caribbean could enter the Gulf of Mexico next week as a depression after crossing over the Yucatan peninsula, potentially reducing the chances it could pose a major threat to Florida later in the week.
