The National Hurricane Center has downgraded the western tropical wave due to a lack of convection. Also, a Hurricane Hunter mission flew out today and determined that the system was not a Tropical Depression quite yet.

The latest IR satellite imagery suggest that the environment for both the west and east wave are still favorable for slow development. This is apparent with the anticyclonic rotation of high level clouds (storm's exhaust), and cyclonic rotation of low and mid level clouds (storm's inflow). The convection must pick up on both waves with in the next 2 to 3 days so that the storms can change their environment; the environment looks like it might be less hospitable in a few days.

The latest Water Vapor satellite imagery also suggests that the west wave has a good amount of moisture surrounding it that should contain plenty of potential energy. I am puzzled why this wave is having such a hard time turning that potential energy to kinetic energy. The east wave has what could be a significant problem when looking at WV satellite imagery. There seems to be a huge plume of dry air in the path of the wave and to the north.

Stay tuned!
