Isaac巔峰為65節 993百帕，NHC兩天前停止發報。
目前殘餘雲系正通過牙買加南方海域，NHC展望Low，將朝猶加敦半島方向行進，數值看好系統在墨西哥灣會有所發展。

1. A weak area of low pressure, associated with the remnants of Isaac,
is located just south of Jamaica.  Showers and thunderstorms
are currently limited, and any development should be slow to
occur during the next day or so.  By Wednesday, environmental
conditions are forecast to become less conducive for re-development
to occur when the system moves toward the Yucatan Peninsula.
Regardless of development, locally heavy rains and gusty winds are
possible over portions of Hispaniola, Jamaica, and eastern Cuba
during the next couple of days while the system moves westward to
west-northwestward across the northwestern Caribbean Sea.
