New Area of Tropical Interest in Eastern Atlantic

13 Aug 2017, 2:35 pm

A new tropical wave off the west coast of Africa is expected to gradually develop this week, and it could pose tropical troubles for parts of the Caribbean and/or the United States next week.

The tropical wave, currently several thousand miles east of the Lesser Antilles islands, is expected to move west, but where it’s headed and how strong it may get, as usual, remain the big question marks.

Both the forecast track and the intensity are highly uncertain. As of Sunday afternoon, the National Hurricane Center (NHC) had given the system only a low chance of development within the next five days.

However, some computer models take the system, code-named “Invest 91-L” by the NHC for tracking purposes, in or near the Caribbean, and some as a hurricane. There is a high degree of uncertainty, as is often the case with a system just moving off the west coast of Africa.

Again, this is a highly uncertain forecast, and our message to you is merely this: keep an eye on it.

But, this is the time of year that any possible tropical development in this part of the world is given a particularly close watch. As we move towards the peak of hurricane season in late August and into September, tropical systems tend to originate in the central and eastern Atlantic, and as they move towards the Caribbean and the United States, they can often strengthen into tropical storms and hurricanes.
