TROPICAL STORM DEBBY
– Debby will not move much today, then the jury is still out on exactly where it goes thereafter, with its track forecast continuing to be a particularly challenging one.
– With the large amount of uncertainty that exists, care must be exercised to not look at the single line of the official National Hurricane Center forecast, or for that matter in this case even the cone, and assume that Debby is definitely is going there — it might, but not necessarily — given the extreme dichotomy in model forecasts the past few days and in the vastly different paths available via the atmospheric forks in the road that exist. Some tropical cyclones have track forecasts which are very straightforward and are of high confidence. This one does not.
– The ECMWF (European) model, in its latest run, has “blinked” first, backing off from its Texas outcome, now showing a track into Louisiana. The GFS (American) is sticking to its forecast of the scenario of the storm going across the Florida peninsula. The GEM (Canadian) model, which had been showing a track into Louisiana, now has Debby going into the Florida Panhandle. Those are “global models.” The latest runs of the two main hurricane models are split, with one (GFDL) forecasting a Florida Panhandle landfall and the other (HWRF) predicting it to be in Texas, but the latter currently being the only model to do that.
