Haven't posted much in this thread, but have been saying all along that folks expecting a big second peak intensity in the GOM may be disappointed. Betting on something as extreme as a cat 4 for a system that has been structurally unstable and quickly expanding in size, during a season with an observed propensity to limit intensity as least excuse imaginable seemed like a risky proposition to me. That said, no issue at all with a very destructive surge potential due to the expanding size.
DELTA will likely intensify at a fairly methodical pace to a secondary peak of high cat 2/low cat 3, before striking the coast as either a low end cat 2 or even high end cat 1.
Regardless, wind will not be the main story, unlike Laura.
