Looking at the latest Air Force Reconnaissance observations, Alberto is indeed intensifying, as forecast by the NHC. Underneath the deep convection to the east of the storm center, the airplane is flying through winds above 80 mph. Of course, the winds at flight level are stronger than those at the surface, but this still translates to a speed of around 60 mph at the surface. In contrast, the Dvorak techinque (a way to use infrared satellite imagery to estimate storm intensity) is only suggesting a maximum wind speed of around 40 mph. The 11AM update from NHC should be interesting. Stay tuned to The StormTrack for more.
