Tracking Invest 94L In Central Atlantic

Tropical development in the Atlantic is looking less likely as a cluster of thunderstorms east of the Lesser Antilles continues to march westward.

The disorganized tropical wave is located well over 500 miles east of Barbados, in the Atlantic.

According to the National Hurricane Center, this weak area of low pressure, dubbed Invest 94L, has looked less organized Monday than it did for a brief time over the weekend.

That's why, for now, the threat of this disturbance becoming anything more than a rainmaker is low. This is not a threat to the United States.

It will be guided along the southern periphery of the Bermuda High on a westward path. The tropical wave will reach the Caribbean around Thursday.

By the time it nears the Caribbean, wind shear is expected to increase, making it more difficult to produce dangerous conditions and intensify.

However, several inches of rain are likely on the islands that this disturbance passes over. An increase in swells and rip current potential are expected late week near the Lesser Antilles. These effects may be confined to a smaller area given the wave's smaller size.

Computer models are not currently expecting much sustained intensification near the islands, so wind may not be a major threat there. We'll keep an eye on it.

The next tropical storm will be named "Dexter."

Nearing August: Tropical Wave Development Typically Increases

There is a notable increase in tropical activity in the southern Atlantic throughout late July and into early August.

This is because dusty, dry, Saharan air – one of the Atlantic's biggest limiting factors – typically disperses and allows tropical waves to produce tall thunderstorms. These thunderstorms lead to a healthier system and could eventually lead to the formation of a tropical depression or storm.

At the same time, water temperatures are often near their annual peak and wind shear is often decreasing.

Development chances also increase in the Gulf and western Atlantic as we approach August.
