I think I can see two plausible low-level "swirls" (circulations). The first one is most evident, and it is centered near 24.5N and 88.6W. It appears to be a legit genuine circulation. This area probably received the 1.5 T numbers. Look at this GOES visible loop. Additionally, I see some signs of a secondary weaker sfc circulation further to the SE. That latter possible circulation is located under the cirrus canopy and convective activity N of western Cuba. You can see both areas highlighted on the graphic. There is strong upper divergence, but this system coyuld get going if the shear relaxes. There's a strong TUTT low over the area, but sfc convergence is decent. At the time, I don't expect development, but upper-air support could be more conducive if shear decreases over the system.
