This is hands down the most extraordinary dropsonde in Atlantic recon history.

173kt peak flight level winds, highest measured so far in Melissa, and not even on the strongest side of the storm.

Updated track map. Starting to drift bit northward - part steering, part cyclonic wobble

This is actually just plain unheard of in the Atlantic

CI# up to 8.2 = 176kt / 882mb (satellite estimates put Melissa at Wilma levels)

Raw back up to 8.4. Final up to 8.0 = 170kt satellite estimate.
Pretty surreal that we're just repeating the last 24 hours, as Melissa sits nearly stationary, contemplating the turn north.

Waving Melissa west.

Rapid intensification gets a lot of attention and is typically part of the last push to category 5.
This wasn't the case for Melissa however. The 24 hours leading up to becoming a cat 5 was one of the most gradual intensifications for any Atlantic cat 5.

Don't see a satellite intensity estimate of 170kt in the Atlantic everyday. Or well, ever.

8.3!!
And an *average* cloud temp of -80C!
This is an astronomical satellite intensity estimate.

Definitely one of the more impressive non-cat-5 satellite presentations.

The NHC forecast for Melissa at 15 UTC today was the first time they have ever projected a hurricane to reach 130kt at 96 hours, starting from a 40kt storm.
Projecting 130kt at 96 hours is rare, just in general.

55F at 11am MDT (10am LST), with a forecast to hit 79F this afternoon at DIA. Low clouds / fog have been holding tough all morning, just now starting to erode.
