Looking at the latest spaghettis we need more info on what steers these things especially if we are anticipating a storm that does a u turn/circle. That would be unique at the very least.

There have been other hurricanes that have done similar loop backs.

Matthew left behind loop certainly possible. Look at these Esther 1961, Ginny 1963 , Ginger 1971 and Ivan 2004. Hermine crawled this year

There is a ridge to the northeast of Matthew that is shifting westward (a subtropical system that developed off the coast of NC) that will stop northern movement and a mid- to upper-level trough approaching the eastern United States that will push Matthew to the east and then possibly back south as it gets caught between the two systems. And then there is TS Nicole although I don’t know if that is having any effect.

Indeed. Two storms in 2004 were loopy. Ivan and Jeanne. Ivan looped back around to FL long after landfall. Jeanne looped around in the Atlantic before making landfall in FL.

Wow it will take a dozen or so hi-tech computers to figure out where that will go.I wouldn’t begin to guess.
Rush is giving his analysis right now he gets worried if the eye stays 50 or more miles offshore.He’s in Palm Beach.
