The latest from NHC suggest that the wind field is expanding. Interesting that a 939 mb pressure should equate to higher wind speed than 115 MPH. Not sure if that is due though to increased wind field though. Basically, it is getting bigger but not necessarily stronger right now. Starting to make the turn too it would seem.
"The central pressure of the storm now at 942 [at the time of that post] is the lowest pressure ever reported with a storm of winds of 115 mph. In a study of the last 10 years, all storms with pressures of 952 or lower had winds of 120 miles or more on TPC bulletins and the average was [125.1 mph] . The only storm I could find with a pressure of 950 and windspeed of 115 was Hugo, another storm i was ranting about when such things were getting reported since the true wind of the storm in landfall situations of tropical cyclones where pressures are falling, will be ramped up. It is my contention that there are higher winds, that the flight level winds are probably down at the surface though maybe not right under the strong winds. But with the pressures so low, the transfer of the wind to the surface is easier to occur."
