Other Disturbances / Areas to Watch
Disturbance 49 is located along 62.5W, in the eastern Caribbean. It is moving to the west near 20 mph. A significant slowdown is expected within the next couple of days. By the end of the week, this disturbance is expected to move into the same monsoon trough that spawned Michael. Model guidance indicates that there could be another tropical storm that forms from this combined system. The chance of development within the next 7 days is 30 percent, with the window for development not opening until this weekend. If development were to occur, the system could move toward the Yucatan by the middle of next week.

Disturbance 51 is located well south of the Cabo Verde Islands along 27W. It is moving to the west-northwest at 11 mph. This motion is expected to continue. The disturbance is showing signs of organization this morning. Environmental conditions appear somewhat favorable for limited development. There is now a 40 percent chance of tropical development. That said, there does not appear to be any risk to the Caribbean. Environmental conditions should become less favorable for development by the weekend. Anything that does develop should dissipate well east of the Caribbean.

Disturbance 48 has become less organized along 42W. It is moving to the west at 11 mph. No development is expected from this system.
