Tropical Depression Nineteen has formed in the Caribbean Sea and is forecast to continue strengthening, according to the National Hurricane Center.

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. Lots of factors in play but Tropical Storm Sara is expected to form this week and could become a major hurricane threatening the US next week.

Tropical Depression Nineteen has formed about 280 miles east of Isla Guanaja, Honduras, the National Hurricane Center said.

Though the impacts are unknown at this time, residents near the Gulf of Mexico are encouraged to monitor Tropical Depression 19.

Tropical Storm Sara formed this afternoon and threatens to bring "life-threatening and potentially catastrophic flash flooding and mudslides" to Honduras throughout the weekend, according to the latest update from the National Hurricane Center. A turn toward Florida is still possible, forecasters said.

The National Hurricane Center forecasts Tropical Storm Sara could get into the Gulf of Mexico after swamping Central America and crossing over Mexico.

The National Hurricane Center has designated an area of low pressure in the Caribbean as “Potential Tropical Cyclone Nineteen,” and forecasts it will strengthen into a tropical storm within the next 24 hours.
