In defense of the ai models usage, it's better this year then last year from what memory remembers. . Idk how it has done with other storms, but with Erin the ai models track was so very much locked in from a very early start, from a rough aspect. As with this storm i saw the euro ai first to show a glancing blow to Carolinas then loops/meander off the coast... way before other non ai models started...
Do they have more data at there resources versus conventional models? Not sure but there deft is some kinda difference, likely not obvious to the naked eye.
