Melissa is, now, very much a picture perfect hurricane, 901mbar and 175mph/280kmh sustained winds at the core vortex walls.
The IR signature is scary, but it shows a slight cooling of the core vortex. This means the storm has stopped "feeding" is will hopefully start dissipating energy, as it drags over landmasses. Unfortunately, that energy will be dissipated by wrecking #Jamaica and #Haiti.
