model. the differences between the two. how stark are they? and can you explain why there is that discrepancy between the two models? >> yeah. little changes, craig, that looking at different wind patterns, sometimes far away from the hurricane make a big difference in the forecast. the steering so far has been a high pressure over the atlantic. but the problem becomes you got a blocking high pressure and eventually losing the steering currents altogether. depending on how strong the models pick up on the subtle changes, sometimes 500, 600 miles away makes a big deal in the forecast. us in the hurricane center don't necessarily look at a couple of mod 'ems but a consensus. we look at the ensemble members of the models. each one with dozens and dozens of model runs in the models and take a consensus and usually the consensus is the winner in the end. >> okay. well, what's the consensus right now? >> i tell you, really close to this forecast. it's really a strong storm. so we're talking about big
