Dare that I say this, but as time is passing by I am beginning to suspect that Irma may be susceptible to a "Charley affect". What is that? I noticed here in Parrish that the heavier squals migrate from east to west, but as they approach the westcoast they dry up...we are now getting some light rain, but Polk County has had heavy weather, including tornado activity, that disapated to mist here in central Manatee County. I have watched the WV loop and what I see is very dry air diving down from the NW toward the storm and moisture is evaporating along the western side. This is what occurred with Charlie. I am hopeful that this trough now in the central GOM will push Irma to the NE.
Could be wishing an outcome. But this affect seems to be influencing the progress of this system.
