From Wunderblog:
...ELSEWHERE in the Atlantic, there are 2 Tropical Waves over the far eastern Tropical Atlantic that have brought along more ‘moisture laden air’ (versus dry, Saharan air). In addition, there are now several somewhat stronger appearing Tropical waves upstream over Africa (only 2 are shown in Fig 9) that will reach the Atlantic later this week and early next week, with one of these systems having a significantly higher potential for development next week.
Fig 8: Aside from TD#2, only 2 significant Tropical Waves are present over the eastern most Atlantic, and they are entangled in the African Monsoonal TROF and/or ITCZ.
Fig 9: Tropical Waves over Africa have become somewhat stronger over the past week, with the easternmost one in the above image showing a mid-level 'turning' on imagery loops.
In the meantime, however, no new tropical cyclone formation is expected during the remainder of the week....
