Mark Vogan: My Explaination for why Lee Could Become a Cat 1 or 2 Hurricane quickly before reaching Louisiana!

Models continue to suggest a relaxing of the wind shear over the northern Gulf of Mexico and if that happens, I strongly believe that Lee will have enough time over those abnormally warm waters to become a Cat 1 or 2 Hurricane. You can see from the above image that the system is lopsided and dissorganised, however, notice the large canopy of convection on ALL sides except the side exposed to shear, all the ingredients are there with extremely warm water beneath and a structure which only needs to see less windshear to stack vertically and we would very quickly see the convective wrap completely around the center. By drawing all the available energy surrounding this system, you would quickly see intensification of Lee and this would really get going.

With a light steering flow, this growth into a hurricane is also made much more possible. With a forward movement of say 10+ mph and only 185mph from shore, I would question whether this had time, but since the steering flow is so light, all it takes for this system to not only be a major rainmaker but possibly a much greater problem for the central Gulf Coast would be if the shear eases and all of a sudden wind, wave and surge is just as much an issue as the flooding rains. Especially if it’s as slow as it is. Think about it, having a painfully slow rainmaker is one thing but having a hurricane of even only 75 mph that is battering the coast for over a day, even more damage is highly likely.
