UKMET was the top overall individual global model on Katrina, by a slim margin. GUNA consensus beat it by a little bit, though.
In this case, with this specific run, though, the fact it isn't verifying as soon as 6 hours indicates the 12Z UKMET may be a squirrely run.
Where is a model that shows the GUNA track. I dont it. Even the colo models dont seem to show it, tho they do have GFDI which seems to work pretty well.
