Well, the easterly wave that moved off of Africa's coast a few days ago is still trying to develop, but it is struggling to exist. Satellite IR imagery has shown weak thunderstorm development near the surface low. In fact thunderstorm activity has been pulsing and at times non-existent (see bellow). This is a problem because the wave is in an environment unfavorable for development and without thunderstorms the wave cannot change its environment for the better... essentially the wave is being choked out.

One thing that might give the wave one last chance to develop is the warm waters in front of its path (see below). These warm waters will release extra energy that the wave can use to create more storms, which could eventually make the environment favorable for further development.

It will be interesting to see how this wave evolves over the next few days... if it survives at all!
