Over the past twenty-four hours or so there has been considerable agreement amongst the various models concerning the forecast track for Dean. This morning I was pointed over to this loop which seems to indicate that the GFDL is now a dissenting outlier. I was wondering if one of our Mets or more experienced storm trackers could speak to what the GFDL sees (or thinks it sees) that would prompt such a drastic swing from the Yucatan towards the Central Gulf Coast. Old data? Bad data? New data? Just curious what the rationale is.
