Sunday Morning Update
Humberto a little weaker
NHC has classified Humberto by satellite classification techniques. As stated by NHC, cloud tops have warmed overnight, indicating weakening. IMO, Humberto may not have been a cat 5, but a cat 4 yesterday. Cloud tops that I have seen with other cat 5 hurricanes seemed to be a bit colder. Anyhow, without direct data from a Hurricane Hunter aircraft - which we did not have - we'll never know for sure.
This morning the eyewall is much smaller. It appears that some dry air was entrained into the circulation overnight, which can be seen on the IR imagery below. The eye is now also clouding over. IMO, this hurricane is probably not quite as high as the official estimate.
