HOLT, Fla., Sept. 2, 2019—The National Hurricane Center is watching four tropical areas in addition to category 4 Hurricane Dorian.

All four areas are expected to develop into some type of tropical system.

The low-pressure system moving generally westward across the eastern Atlantic Ocean a few hundred miles west of the Cabo Verdes Islands is expected to form into a tropical depression in a day or so, according to the NHC.

The NHC gives it an 80 percent chance of becoming a depression in the next 48 hours.

The low-pressure system in the south-central Gulf of Mexico is moving slowly westward/west-southwestward toward the Mexican coast.

It has a 70 percent chance of becoming a tropical depression in the next five days.

The low-pressure area located south of Bermuda and east of Dorian has a medium 30 percent chance of further development during the next couple of days, according to the NHC.

However, upper-level winds may prevent this from developing further later in the forecast period.

Finally, the tropical wave that hasn’t yet emerged off the coast of Africa already has a 50 percent chance of developing into a tropical depression late this week or during the weekend, according to the NHC.

The next name on the hurricane list is Fernand followed by  Gabrielle.
