The NAM-ETA is not to be used for anything tropical. It was never designed to be a tropical model. However, the NAM-ETA is about to be replaced by the WRF NAM (NAM-NMM) in mid June. 'Supposedly' it is going to be another good guidance tool for tropical weather. It will certainly get a good test drive this summer.


I didn't know about th NAM-NMM. Will this be available on the regular NCEP site?

Yes it will be. It is actually already there if you click on the Experimental Page. Go to the experimental page and click on the NAM forecast. That is the new NAM-NMM (with WRF framework).
