Irma is an extremely impressive hurricane in both infrared and
visible satellite images. Experimental GOES-16 one-minute visible
satellite pictures show a distinct 25-30 n mi wide eye with several
mesovortices rotating within with eye. The aircraft have not
sampled the northeastern eyewall where the strongest winds were
measured shortly before 1200 UTC this morning, but the Air Force
plane will be entering the eye in that quadrant momentarily. A peak
SFMR wind of 154 kt was reported, with a few others of 149-150 kt.
Based on these data the initial intensity is set at 155 kt for this
advisory. This makes Irma the strongest hurricane in the Atlantic
basin outside of the Caribbean Sea and Gulf of Mexico in the NHC
records.
