Recent scatterometer data show that the system has opened up into a 
northwest to southeast-oriented trough.  Therefore Claudette has 
dissipated as a tropical cyclone and this is the last advisory.  The 
remnants of Claudette should continue to move rapidly 
east-northeastward and weaken over the next day or so.
