Windspeed Posted September 5, 2017 Share Posted September 5, 2017 Concentric eyewalls on hurricane hunter radar: That radar imagery does not show much of a moat at all between IEW and OEW. The IEW looks very intense with excellent structure. I am not so certain this couldn't just continue to intensify a little more or at least maintain intensity for quite a while. The diameter of the IEW may even have to shrink some before it begins to show signs of weakening. Link to comment Share on other sites More sharing options...
NJwx85 Posted September 5, 2017 Author Share Posted September 5, 2017 Looks like the eye passes right over the Southern tip of Grand Bahama. I believe Andrew did that. Link to comment Share on other sites More sharing options...

Nothing wrong with assimilated data, hence track modeling should be fine. Again though the overall consensus is that the core stays north of Cuba. Gotta see what this trough in the east does this weekend and if it is strong enough to erode some of the ridge or if the ridge will hold its ground Link to comment Share on other sites More sharing options...

NJwx85 Posted September 5, 2017 Author Share Posted September 5, 2017 Well the ridge is rebuilding, so all this means is landfall is probably further Northeast. Maybe the Carolinas or further North. Link to comment Share on other sites More sharing options...

NJwx85 Posted September 5, 2017 Author Share Posted September 5, 2017 That ULL to the NE is really pesky this run, and it's starting to feel the trough over the Canadian Praries. This could do something crazy like try to run it right up the East coast. Link to comment Share on other sites More sharing options...
