Love these plots from Kim - that blue point north of the Gulf Stream is important. Surface waters support a TC (25-26C) but quickly drop off below. A strong storm will upwell that and induce more weakening. Coupled models like HWRF/HMON/HAFS-B will capture some of this effect. https://t.co/Ft2lxTZu8c
