Meteorologists have been tracking the storm for the past week, with its chances of forming increasing gradually. Tropical Storm Sara is expected to form by Thursday morning, becoming a hurricane by Friday night and a major hurricane by Saturday night, AccuWeather said.

Tropical Storm Sara now threatens to wreak havoc over Central America with days of heavy rain. Its remnants could then send lots of rain toward Florida.

A somewhat rare November storm system is gathering steam in the Caribbean Sea. Tropical Storm Sara will eventually make a turn to the east and Florida.
