New tropical wave being tracked, now two in Atlantic

Update 2 p.m.: Two tropical waves are now being tracked by the National Hurricane Center with one getting a low chance of development and the second a 40 percent chance.

Neither are expected to be long lived at this point as they travel toward drier air, slightly cooler waters and areas with higher wind shear.


The wave that popped up Wednesday morning is about 350 miles south-southeast of the Cape Verde Islands. Some development in the short term is expected.

The new system, which is about 1,700 miles east-southeast of the Leeward Islands, is moving west at 30 mph and has a 30 percent chance of development over five days.

Hurricane center forecasters said if formation occurs, it could be this weekend when the system is closer to Lesser Antilles and Puerto Rico.

Previous story:

The National Hurricane Center is giving a cluster of thunderstorms off the coast of Africa a 40 percent chance of strengthening over the next few days, but it is moving into a less accommodating environment and could fall apart by the time it reaches the central tropical Atlantic.

The wave is moving west-northwest at about 10 to 15 mph.

As of the 8 a.m. update, forecasters said the wave was about 400 miles southwest of the Cabo Verde Islands.

The hurricane center is using the official name Cabo Verde instead of the more commonly used Cape Verde to refer to the islands. In 2013, the Cape Verdean government determined that the Portuguese designation “Cabo Verde” would henceforth be used for official purposes.

If the waves moves to much to the north it will run into a thick patch of Saharan dust, which works to kill storms because of its low relative humidity.

Also, slightly cooler sea surface temperatures are in the system’s path. For a tropical cyclone to develop, it needs temperatures of at least 80 degrees Fahrenheit or 26.5 degrees Celsius.

The map below shows sea surface temperatures just below 80 to the west of the wave.
