It is premature to think that Ida will be tropical and deep enough vertically to survive into what currently is a very hostile upper environment other than immediately over the storm. That said, there has been considerable discussion as to the evolution of the old dying frontal remains in the extreme SW Gulf of Mexico and Bay of Campeche into becoming a subtropical or hybrid system later this week. It is highly doubtful a pure tropical system will evolve, however a subtropical system is more likely to be the result given the environment later in the week and where upper level features are progged to be. In that event, it is possible an approach to a US landfall along the Gulf of Mexico is possible.
