热带风暴“艾萨克”再度减弱 Isaac Weakens Again

美国气象预报人员把热带风暴“艾萨克”降级为低气压，但同时警告说，美国南部地区所面临的威胁还没有消失。

美国国家飓风中心说，“艾萨克”星期四经过路易斯安那州北部，风力已经减弱。预计，“艾萨克”向北移动的过程中还会带来降雨。气象预报说，到星期五为止，路易斯安那州、密西西比州、阿拉巴马州和阿肯色州某些地区的降雨量可能多达63厘米。

美国国家飓风中心警告说，路易斯安那州东南部和密西西比州可能还会发生洪水，并可能出现龙卷风。

气象预报人员目前正在密切监视一个代号为“柯克”的热带风暴。

U.S. weather forecasters have downgraded Tropical Storm Isaac to a depression but warn the danger to the southern United States from the system is not over.

The National Hurricane Center says the slow-moving Isaac weakened over northern Louisiana Thursday.  The system is expected to produce more rain as it moves toward the north.  Forecasters say isolated parts of Louisiana, Mississippi, Alabama and Arkansas could get as much as 63 centimeters of rain through Friday.

The hurricane center warned there could still be more flooding across southeastern Louisiana and Mississippi and that tornadoes are possible.

Forecasters are now keeping a close watch on another tropical Storm  Kirk.
