An appropriate theme song for Dorian (FYI lyrics start at 30 second mark)

Best looking tropical wave I've ever seen! With this vigorous mid-level circulation you just can't write it off even if pressures are high. This is the exact same situation as how Andrew formed and we all know how that turned out. I'm not sayin this storm will be anything like that but shear will be decreasing and it'll be traveling over very warm waters in the next few days.

I don't know. There's a lot of activity over Cuba right now. What if/is it possible that Dorian absorbs that activity or is absorbed by that activity - and flares all over again, but this time in the Gulf?

Thoughts?

Convection over cuba and islands are of the normal low natural convergance, and lapse rates due to afternoon maxima over land. They will not assist in any way because they by themselves are not part of the normal mechanism for a tropical cyclone. So the cyclone can't really "absorb" that convection. Also make note of the local time (-4 or -5) from UTC and you will see in multiday loops that this activity happens almost every day in the afternoon. Once the storms die out, it is the beginning of the process of cooling off leading to oceanic diurnal maxima for convection, and THIS does help sustain would be and current cyclones.

DMAX occurs around 4-5AM local time for the zone the cyclone is in. Roughly.

Remnants of Dorian do not seem to have made much progress west looking at that image. Convection still north of PR.

Dorian has some things going for it. Mid level shear has dropped off some in the past few hours and the TUTT seems to be dissipating. He's also developing convection on the northern side in the last couple of frames. The trend is for the mid and upper level shear to continue to drop, at least for now.

Same story everyday. No convection left by sunset, tons of convection by sunrise.
