Indeed , Bertha is doing very well for herself. ADT is now coming in at 115 knots, raw, as well as 3 hour averaged.
Much has been written here about Bertha's so-called surprisingly rapid intensification. However, this should be considered within the context of of NHC not having had the advantage of recon in and out of there. As early as late yesterday afternoon there were clear indications that Bertha may had already become a hurricane, but owing to the lack of quality center fixes, not to mention the lack of any actual recon flight data at all, Dvorak intensity estimates were not well-pegged to her actual center, and this often tends to give a negative bias to the final T, which, if left uncorrected, then also gets fed into the models, many of which have been way off on her actual intensity, and a bit off on location.
The fact that the CIMSS ADT product is now hitting regular, averaged T numbers of 6.0 or better owes a great deal to the clear eye offering an accurate place to start. Bertha may very well already be a major hurricane, and may have been one for a few hours. Bertha may have been a hurricane for almost 24 hours. Reanalysis will be very key to the record books, for this one.
