Follow spaghetti models, tracking for a tropical depression in the Caribbean Sea that could threaten Florida as a hurricane.

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.

Forecasters at the National Hurricane Center are urging residents of the eastern Gulf Coast, particularly Floridians, to monitor the forecast closely because there could be an opening for the storm to reach the US next week.
