Remember that the system will be moving almost inline with the shear,,,so that wont weaken it as much as the slightly cooler water temps........Thing is,,,when will Wilma peak out at and where? Thurs night sounds good to me.... then with her eyewall getting sheared over and pressure rises from its lows of Thurs night due to Friday daytime dur, shear and cooler water temps,,,expect anywhere from 20mph-30mph weaker during the day. Friday night she might just hold the intensity when she moves along almost with the shear flow.
I know it might sound confusing to some but everything is speculation,,even in the next 24 hours as she hasnt gone NW yet and isnt forecasted to until tomorrow night. My offical forecast wont be until Weds night.
