  1. how many weenies does it take to will a southward turn???
  2. Now that's a better view, and it does indeed look like we are in the beginning stages of an ERC. Kinda freaky how close this thing is to Miami.
  3. This doesn't really look like the textbook start to an ERC - there needs to me a more defined outer band of convection. Also, this is pretty far away from the radar site so it's hard to make conclusions. MW imagery is probably better at this point.
  4. This is a really good point. Wouldn't take an abnormally large model error to put an eyewall on the coast.
  5. From the paper I included, "along-track error" looks to be 50-70 km at these ranges, and total error is ~ 150 km. So 70 mi sounds about right.
  6. Take a look at this paper. Pretty good model verification resource.
  7. GEFS and EURO are largely the leaders in terms of total track errors.
  8. Perhaps but it's objective and accurate. We've never seen a hurricane this intense this far north in the Atlantic Basin outside of the GOM in modern historical times. And Dorian may not be done. If it continues to drop pressure another 10-15mb under the influence of the ridge and above mean background pressures, the windspeeds are going to continue going up. Sorry, just teasing (Phil mainly). You're right. The last very intense hurricane in this area was Andrew, and we're several mb below Andrew's 922 mb, and poised to surpass andrew's 175 mph max.
  9. This is a little bit of a baseball stat ;-)
  10. Morning ensemble guidance has pretty much converged on a solution: (HWRF aside)
  11. This should end the discussion. There is absolutely no conceivable political motivation on their end for fudging the numbers. They are doing the best that they can given the current information. Regardless, the storm's intensity is what it is, regardless of the current best track estimate. If it is indeed a cat 5, calling it a cat 4 in the best track doesn't actually make the storm weaker. Post storm analysis will shed more light on the situation. Otherwise, get on with your nights.
  12. FWIW, the EURO and the GEFS tend to out-perform the UKMET. Source:
  13. Hurricane models are fine to use as track guidance. Generally, I believe the global models such as the GFS and ECMWF verify a little bit better - particularly at longer ranges. The most informative products to look at are probably the GEFS (GFS ensemble) and ECMWF ensembles, because they give you a sense for the uncertainties in possible outcomes. So I would probably start with these, and then refer to the hurricane models for corroboration on track, and for some additional insight into intensity. I like this site for ensemble tracks: Edit: it is also informative to look at run-to-run variations in the deterministic GFS and ECMWF (and the hurricane models for that matter). For instance, the Colorado State site shows spaghetti diagrams that shown runs initialized at multiple times for the deterministic global runs and for the hurricane models:
  14. You're right on the "assigning agendas" comment. My apologies. The forecast should be viewed from a probabilistic, rather than deterministic standpoint at these lead times (I'm sure you would agree). My statement was simply that the dynamical guidance suggests a high probability of the center staying offshore of FL, and a low probability of a FL landfall. NHC (the experts) agree with this assessment. Yes, there remains a possibility that guidance will swing back south, but it's not the most likely outcome.
  15. I just re-read my post, and it sounded more informative than hysterical, so the "breathe into a paper bag" comment was largely uncalled for. I'm just trying to be objective here. There is nothing wrong with calling out cherry picking and wishcasting. It's probably beneficial for some of the forum readers to know when people are making emotional and unsubstantiated projections, rather than sound meteorological analyses.
  16. Any east coast surfers in this thread? The slow storm motion and potential northward track could mean an extended timeframe of really nice mid period swell for many locations.
  17. A lot better CDO symmetry since this morning.
  18. Nobody said that models are rock solid. My statements referred to probability, not certainty.
  19. Well, to be fair I should have referred to the lack of a FL landfall. Still a bit far out to start speculating about the outer banks.
  20. To me it looks like they bought into the global ensembles, rather than the hurricane models, which show the OTS solution as the most likely outcome.
  21. Nobody is ringing the "all clear" bell. Just saying that the most traditionally reliable model guidance all have an OTS solution, and have been trending so for the last several cycles. This is the most likely outcome given the best information we have right now, despite the desire by many in this forum for a Florida hit. To suggest that a FL landfall is the "most likely solution" at this point is a wish cast, and not based in reality. Does that mean that a FL landfall is out of the question? Absolutely not - it's just an increasingly less likely outcome. The NHC forecast responsibly reflects this.
  22. A lot of wishcasting and cherry picking model runs going on here... just sayin.
  23. Why? It's pretty consistent with the last several rounds of the most reliable model guidance.
  24. I doubt there is any science behind this statement.
  25. Lets not forget that this is the HMON. If i had a dime for every time HMON obliterated Miami with a Cat 5 hurricane, I'd have like 20 or so dimes by now.
