Here is what Dr Jeff Masters said about this wave in his blog yesterday:

African tropical wave may develop
A strong tropical wave with a moderate amount of spin is moving off the coast of Africa this morning. The wave is under about 10 - 20 knots of wind shear and has sea surface temperatures beneath it of 27°C. These conditions are probably too marginal to allow development over the next two days. As the wave moves westward away from Africa over the next few days, wind shear should slowly decrease and the SSTs will warm, potentially allowing for some slow development.

for the north atlantic...caribbean sea and the gulf of mexico...

1. Showers and thunderstorms associated with the broad area of low
pressure located just south of the southern cape verde islands show
some signs of organization. Conditions appear favorable for
development of this system and it could become a tropical
depression during the next day or two as it moves generally
westward at 10 to 15 mph. There is a medium chance...30 to 50
percent...of this system becoming a tropical cyclone during the
next 48 hours. Associated showers and thunderstorms with locally
gusty winds should continue to affect portions of the cape verde
islands during the next 24 hours.

Elsewhere...tropical cyclone formation is not expected during the
next 48 hours.

Time for the annual march across the Atlantic from the African coast.
Let's hope we don't have too many this year.

Yes it IS that time...
There's another system over Africa now that will probably become the next car in the train...
