thanks http://hadar.cira.colostate.edu/ramsdis/online/trop_ge_vis_float1_0.html --Previous Message-- : Definitely looks like a rotating MCS or MCV. : : Convection has actually died off a bit over : the last 24 hours. : : Cloud tops have dropped from 45k-ft to about : 35k-ft. : : Rain rate has also dropped as well. : : It looks like this is due to the fact shear : has dropped around it as well. Mostly : likely due to UL divergence of the MCV. : : It was 30 knots about 12 hours ago, now its : about 20 knots. : : Reduced shear actually weakens an MCS / MCV. : : MIMIC-TPW shows a concentration of Theta-E : approaching the convection. : : This could flare the convection and since : shear is dropping, this could transition to : a TC if it gets over open water. : : COC is over currently over Cuba. : : Best chances is if it gets over to the Cat5 : generator. : : : : : : : : : : : : : : : : : :
