I have never trusted the BAM models and i am not so sure that the NHC does either. They talk more about the other models, like NOGAPS, UKMET, etc...than they do about BAM. Both the deep and medium models always seem to cluster close together and always seems to be away (west and or south) of the other models. They are just models and can't be relied on solely. Like the latest run i have seen....Both BAM models have Irene moving more west and wsw in the insuing days whereas the other models are more westerly than previous days - they are not as extreme as the BAM.
