i wouldnt be surprised if those invests on the old system 90L started again today, since just southeast of jamaica theres that old familiar turning, but now with deep convection firing on its immediate southeast semicircle (and less indication of tremendous shear).
91L did what i should have expected, seeing as it wants to make tropical cyclone credentials. at just the last moment the small and ill defined low suddenly developed a considerable amount of convection and banked right, now seeming to drift north along the upper florida coast. its headed for wilmington, just like all proper atlantic hurricanes, of course.
well back in the realm of reality i think it's responding to the pressure falls to the northeast. that system, visible last evening but considerably stronger today, is rocking the boat as far as low level steering goes.. maybe it will gobble up 91L. very cool waters beneath it though, low to mid 70s. i very much doubt it will come to anything.
out west the mcc hasnt worked its mid level low offshore yet. maybe later today.
summary IMO the likely story today is southeast of jamaica.
