Some key things that made Ernesto basically an "er- nothing" would be the following:
●The forward movement was much higher then a normal typical TC setup. I feel that if it was more or less going slower then 10 mph, it would of better absorbed the ocean heat and possibly not gotten into such crappy environment.
●Dry air, dry air, dry air! That system could not shake the dry air that was getting wrapped around it.
●running into shear at various times on top of the other negative factors didn't help any.
● the front it ran into kinda also hurt it to an extent. Right as it was looking and acting betterbefore Bermuda, the front started hurting it. Again very much ties into the whole fast forward motion
