Looking for feedback on my IR choice. Do you like this one, or do you guys think one of the other color IR images would look better, like the rainbow?

Not necessarily. That MAY be true for a tropical cyclone's core, but Alberto is not very tropical now. The entrainment of cooler, drier air has killed off all convection and will prevent those stronger winds from extending down to the surface. It's possible that the normal 0.8 x FL wind equation may have to be lowered to 0.5 or even 0.6 times the FL wind for such a storm. The storm is passing over a couple of buoys now. So far, max winds are 40 kts. I think this storm has a few pockets of 40-45 kts north of the center and that's about it. Looks like a frontal low now.

So we still aren't considering it very tropical even though its eye is 7C warmer than the immediate surroundings? Or is that not a good indicator of tropicalness. . .
