Irma has become a real monster tonight, with the pressure dropping to 916 mb and winds of 185 mph with gusts well over 200 mph. The pressure dropped significantly in the late afternoon and evening but it often takes a few hours for the winds to increase. For Barbuda, it does not matter, the island is about to be hit with 185 mph winds and that means few structures or trees will survive it.
The effect of this on Barbuda will be the same as an EF 4 tornado hitting the entire island.
Here is the pressure and wind trace from the buoy at Barbuda. I suspect this station will be blown to bits overnight.
The picture below is the station on Barbuda:
