But Charlie, as I recall, was a mature storm when it entered the gulf; didn't appear as ragged as Arlene. Remember also that Arlene is handicapped in the SW quadrant- nada. There is no 'enclosure' and may become less viable with landmass interaction.
There is little chance that meteorologists can solve the mysteries of weather until they gain an understanding of the mutual attraction of rain and weekends. ~Arnot Sheppard
