New Tropical Depression Forms Off Southeast Coast

A cluster of showers and thunderstorms east of the South Carolina coast has sufficiently organized enough to be declared a tropical depression late Monday afternoon.


What You Need To Know

  • The depression will move up the coast over the next couple days
  • Most of the impacts will remain out in the Atlantic
  • Two more tropical waves are in the Caribbean and open Atlantic

The forecast keeps the depression offshore as it moves off to the northeast at 12 mph. Conditions could allow the system to strengthen some into a tropical storm over the next day or two as it heads into the open Atlantic.

If it does become a tropical storm, the next name on the list is Nana.

While the center will remain offshore, rough surf and rip currents are possible along Carolina beaches through midweek. 

Strong wind shear is forecast to develop later this week, which should dissipate the storm as it heads out to sea. 

Two other systems are moving west across the Atlantic. One has entered the Caribbean Sea, while the other is west of the Cabo Verde Islands.

The one in the Caribbean may also develop into a tropical depression in the next couple of days as it tracks to the west. Its current forecast track takes it well south of the United States. 

Meanwhile, the one in the open Atlantic is still disorganized and shouldn’t see much development in the near future. Another tropical wave over Africa is still a couple days away from reaching the Atlantic.

The average peak of the hurricane season is approaching and tropical systems can develop just about anywhere in the Atlantic basin this time of year. In the first ten days of September, they have formed anywhere from the Gulf of Mexico to off the coast of Africa and everywhere in between. This is also the time of year when some of the strongest hurricanes happen.
