T numbers, unfortunately, do not serve as clear-cut a dividing line as we humans would like them to. And, they are not always close to accurate. Just because a given system is estimated to be a certain T number that is typically associated with a numbered depression or even a named storm, just does not mean it is so. A case in point could be 94L, where it is possible that while SAB (SSD) assigned it 2.0 to 2.5, it did not in fact have a closed low at the surface (or much of one). Certainly it unraveled on approach to the Antilles.

OTOH, 96L does have a closed surface circulation with deep convection blowing up on top of it that we can be sure of. A case could be made that its winds are a little light compared to your average upgrade to TD, but this doesn't always preclude an upgrade to TD in and of itself.
