Conventional and Low-earth orbit satellite data indicate that showers and thunderstorms associated with a tropical wave located about midway between the west coast of Africa and the Windward Islands have increased and become better organized since yesterday afternoon. Image: NHC

The system is one of two tropical waves forecasters are tracking.

The system is expected to approach the Windward Islands on the eastern edge of the Caribbean by the end of the week.

The next named storm in the Atlantic basin will be Fiona.

According to the NHC, shower and thunderstorm activity have become a little more concentrated associated with a tropical wave located midway between the west coast of Africa and the Windward Islands.

“Some additional development of this system is possible over the next several days while it moves generally westward to west-northwestward over the central tropical Atlantic and approaches the Windward Islands by the end of the week.”

Eastern Tropical Atlantic

A tropical wave located less than a couple hundred miles southeast of the easternmost Cabo Verde Islands is producing a small area of disorganised showers and thunderstorms.

Environmental conditions appear only marginally favourable, and any development of this wave should be slow to occur while it moves westward or west-northwestward across the eastern tropical Atlantic through the end of the week, the NHC said.
