Tropical Storm Sebastien Path, Forecast: Storm May Become a Hurricane in the Atlantic

The National Hurricane Center is wary of a tropical storm currently raging in the Atlantic potentially developing into a hurricane before the weekend.

Tropical Storm Sebastien, which is currently positioned in the central Atlantic Ocean, is reportedly gaining strength. The storm is expected to develop into a late-season hurricane on late Thursday into Friday, the NHC said.

Rare for this late in November, the hurricane likely won't have an impact on land and there are no coastal warnings in effect.

Sebastian is currently located about 350 miles north-northeast of the Leeward Islands—a chain of small islands east of Puerto Rico. The storm appeared to be headed out into the open ocean as of Thursday morning with sustained winds tracked at about 60 miles per hour. It's expected to remain over open ocean, although wind speeds are forecast to strengthen by Thursday night.

However, Sebastian is only expected to be a low-intensity hurricane—Category 1 at the highest—and will likely weaken into an extratropical cyclone in about 48 hours. The storm is expected to completely dissipate by the end of the weekend.

It's been three years since last time a hurricane developed in the Atlantic this late in November. Tropical Storm Otto was deemed a Category 3 hurricane when it made landfall on the Nicaragua and Costa Rica border on November 23, 2016.

There have been six other hurricanes tracked in late November since meteorologists began watching storm activity via satellite in 1966, including 1969's Hurricane Martha, Hurricane Karl in 1980, Hurricane Lili in 1984, Hurricane Nicole in 1998, Hurricane Olga in 2001 and Hurricane Epsilon in 2005. However, those hurricanes remained over the open ocean and failed to make it to land before blowing out.

Sebastian will mark the 18th hurricane to hit the Atlantic in 2019.

The last hurricane to hit the Atlantic this year was Hurricane Pablo, which developed into a Category 1 hurricane in October before reducing back down to a tropical storm within a few hours. That storm also remained over the open ocean.

The worst hurricane of the 2019 season was Hurricane Dorian, which slammed into the Bahamas in September. Dorian was a Category 5 hurricane with maximum sustained winds at 160 miles per hour when it made landfall. The storm caused devastating damage to the islands and claimed the lives of 56 people.
