Weak tropical waves in Atlantic have low chance of formation in next couple days

It would be at least two weeks before two weak tropical waves could be anywhere near the East Coast, according to the National Weather Service.

For the moment, meteorologists are leaving it up to the National Hurricane Center to track the disturbances, said meteorologist Jonathan Lamb, in the North Charleston office.

“A lot of times they just dissipate before they develop,” he said.

The first tropical wave is located about 350 miles south-southeast of Cabo Verde and is accompanied by a low pressure system producing an area of showers and thunderstorms, according to the Hurricane Center. The chance for formation over the next 48 hours is low at 30 percent. The chance is medium over the next five days at 40 percent, but a weather outlook states environmental conditions are expected to become less conducive for development early next week when the system is over the central tropical Atlantic Ocean.

The other tropical wave is located about 1,700 miles east-southeast of the Leeward Islands and moving west at about 30 mph. Environmental conditions are expected to be somewhat conducive for development this weekend when the disturbance could be near the northern Lesser Antilles and Puerto Rico. The chance of formation over the next 48 hours is low at 20 percent and low again over the next five days at 30 percent.
