The center did look pretty tight on visible earlier today.
Some convection around the center now.
Hurricane models are showing a 25-30mb pressure drop before it hits the Yucatan.
I take these models more seriously in the near term with storms over warm water in low shear, with a small core.
Ernesto, Micheal and Harvey all experienced these kind of deepening rates when they were near the Yucatan.
Watch closely the next few hours if the burst over the center continues to grow, it could be an impressive 6-18hr RI event.
