The Atlantic 'wave train' appears to be gearing up for a period of increased activity - at least 'active' for early July. Wind shear is not an inhibiting factor from 25W to about 65W. The Atlantic upper ridge is not significantly strong but it has elongated east-west thus providing a steady movement westward for any tropical waves emerging off the west coast of Africa. Any developing systems at the lower level are not likely to outrun their convection at the upper levels and SSTs are now warm enough to enhance any developing system.

The wave at 10N 50W at 06/09Z has maintained good structure overnight and is certainly an area of potential development in the next day or two. Also worth watching is the wave at 10N 28W at 06/06Z - this one may turn out to be the more significant of the two - and it should be near 15N 50W by mid-day on Thursday. The GFS seems to have initialized fairly well on the second easterly wave.
Cheers,
