Additional Hurricane Discussions

The NOAA’s 10 a.m. updated included some additional details worth noting.

“The initial motion is a rather uncertain 270/4. Barry is being steered by a weak low- to mid-level ridge to the north, and a weakness in the ridge is forecast to develop during the next 24-48 h. This should allow the cyclone to turn northwestward and eventually northward. However, there is a large spread in the track guidance. The HWRF and HMON forecast Barry to move almost due north from its current position with a landfall in Mississippi, while the UKMET takes the cyclone to the upper Texas coast. The GFS, ECMWF, and Canadian models lie between these extremes. Overall, there has been a slight eastward shift of the guidance envelope, so the new forecast track is also adjusted slightly to the east. It should be noted, though, that the new track is west of the consensus models.”
