Other Disturbances / Areas to Watch
The remnants of Isaac will enhance shower and thunderstorm activity near and around Jamaica over the next couple of days. Though the system continues to have some organized thunderstorm activity and rotation, it is not in a favorable environment for redevelopment. We think that Isaac has a very low chance (10 percent) of redeveloping. It will likely remain weak and could completely dissipate over the next day or two. Given the time of year, we will continue to monitor the disturbance.

Disturbance 39 is along 34W. It is consumed by dry air. It is moving west near 15 mph. It is expected to remain weak over the next 5-7 days as it pushes westward. No development is expected.
