Phil..I think you'd be wrong on this one. They (NHC & Hydrometeorological Prediction Center) are still labeling the sysytem as the "remnant circulation of Ivan)....The Hydrometeorological Center even goes so far as to refer us to local weather service offices for furthur updates on this system (I assume since it is back over water and no longer under their jurisdiction???) Sounds to me IF ( a big IF) this cranked up again, they would reinitiate advisories as Ivan.

As for historical reference of the NHC reinitializing advisories on rejuvinated systems, we need look back no further than 2001. Both Chantal and Dean weakened to open waves before restrengthening back into tropical storms. In both cases, the NHC continued to use the name already given the system.
