DEPRESSION DEGENERATES TO AN OPEN WAVE LAST POST ON THIS SYSTEM

JULY 7, 2017 0500 PM EDT

TROPICAL DEPRESSION FOUR DEGENERATES INTO AN OPEN TROPICAL WAVE ONCE AGAIN.  DRY AIR AND FAST FORWARD MOTION DID THIS SYSTEM IN.  THIS WILL BE THE LAST POST ON THIS WEATHER SYSTEM UNLESS REGENERATION OCCURS.

TROPICAL WEATHER OUTLOOK JULY 7, 2017 1215 PM EDT

Tropical Wave # 1 west of the African Coast has a lot of dry air and Sahara dust intruding into the surrounding of this wave.  This minimizes the development of thunderstorms along the northern axis of the wave.  However there seems to be some thunderstorms along the southern axis of the wave at present.

Tropical Wave # 2 over the East Caribbean is also encountering dry air, Sahara dust and wind shear.  The likelihood of development is not likely at this. time

Tropical Wave# 3 is is encountering wind shear and this wave is moving over the Yucatan.

Elsewhere tropical cyclone formation is not expected for the next couple of days.  I will be monitoring to coast of Africa next week for another possible strong wave.

TROPICAL DEPRESSION 4 JULY 7, 2017 1051 AM EDT

Tropical Depression 4 is still moving too fast and is presently still moving through dry air.  Neither of these conditions are favorable for this system to continue to develop.  More than likely this system will have to be downgraded to an open wave as it continues to track toward the west-northwest.

I am working on the Tropical Weather Outlook maps and should have it posted here within an hour or so.  Sorry for the inconvenience its just me doing all this.
