Invest 96L — 70%/70%

[tiger_deF]

After a parade of struggling invests which have failed to materialize, it looks like the Atlantic, in this anemic season, may actually be capable of producing a potentially long-tracking hurricane!
96L is not currently a threat to land, and the vast majority of models show this system recurving out to well east of the CONUS

0Z UKMET: doesn’t quite get it to Dolly strength but still has it as a TD although this run then weakens it while moving rapidly WNW in the MDR followed by a reformation 2 days later moving W much more slowly toward the SE Bahamas:

*Almost* unanimous model support for *some* development but it is apparent this system has serious hurdles ahead of it. There is likely a window for development/strengthening over next few days, but then it hits a wall of shear, so options at that time are dissipation or weakening. Beyond that, location will be everything. If the system survives into the SW basin, there could possibly be an area of lower shear allowing for development as it likely recurves. If the system goes into Caribbean, it will be heading towards its grave. You're starting to see even the GFS back off on its latest run to a more realistic scenario given the harsh conditions ahead of the system. I am fairly confident this becomes a named storm but I do not think it has much of chance to be a long-tracked hurricane, and it likely won't have much window to intensify at all unless it makes it through the TUTT intact. Probably looking a weak, sheared TS for awhile

12Z UKMET: similar to 0Z run with TCG by tomorrow along with rapid WNW movement in MDR along with it barely reaching TS status before weakening back to a TD though this time it remains a TC and strengthens back to a TS late moving much more slowly WNW near SE Bahamas:
