After rapidly intensifying over the past day or so, NOAA-P3 aircraft data indicate that Melissa's intensity has leveled off this
morning. Melissa remains a very formidable hurricane on satellite imagery, with a clearing eye quite evident on morning visible imagery, and the eye temperature has warmed to +15-20C. Meanwhile, the eyewall convection continues to remain robust with cloud tops as low as -75 to -80C encircling the core. With that said, the eye presentation from the Kingston, Jamaica radar is not as pristine, with the eyewall occasionally open on the east side, and some evidence of concentric bands forming off and on. Zooming out a bit, there still remains some evidence of light to moderate westerly
shear undercutting the expanding storm outflow, and Melissa’s primarily rainbands are distributed mostly on the eastern side of the circulation. NOAA-P3 aircraft data this morning had a peak 700-mb flight level wind of 120 kt, and Tail Doppler Radar (TDR) wind retrievals were up to 129 kt at 0.5 km, and 129 kt in the 500 m average of a dropsonde launched in the north eyewall. While this data would support a somewhat lower intensity, the subjective and objective satellite-based intensity estimates are mostly higher, ranging from 115 to 140 kt. The initial intensity will be held at 120 kt, on the lower end of those estimates, and this value could be a little generous based on the aircraft data.
