Invest 97L has become a much weaker and a much more complex system. Circulation of an upper level low centered at 26.6N 71.8W at 21/15Z is hindering the chances for further development of Invest 97L. The ULL is moving west at 12 knots and probably will remain the primary player - could even transition into a subtropical type of system, but doesn't have too much time to do this. Invest 97L has weak cyclonic turning, probably mid-level, near 20.6N 70.9W at 21/15Z - about 150NM east of Great Inagua Island and the Invest area is moving to the west northwest at about 12 knots. Upper level progs keep the ULL moving west for the next 3 days toward the lower Texas coast. A strong southerly shear zone is maintained to the east of the ULL. With the two systems moving in tandem and with the windshear continuing, I'm beginning to think that the current high development chances for 97L are significantly overstated and that a lower probability for additional development may soon be in order.
