It could, but the low-level circulation can take advantage of the warm SSTs in the area (31C) to aid in its further development. The MLC could build down to the surface - normally a much slower process. This gives the LLC an advantage, i.e., it can develop faster, become stronger and eventually create a new 'stacked' system that would overpower the old MLC. Of far more importance, the old MLC is currently experiencing about 25 knots of northeasterly shear. The LLC about 10 knots, so it has a much better chance, IF Emily redevelops, of becoming the predominant center. ED
