Irma Turning Into Monster Hurricane: “Highest Windspeed Forecasts I’ve Ever Seen”

Hurricane Irma continues to strengthen much faster than pretty much any computer model predicted as of yesterday or even this morning. Per the National Hurricane Center’s (NHC) latest update, Irma is currently a Cat-3 storm with sustained winds of 115 mph but is expected to strengthen to a devastating Cat-5 with winds that could top out at 180 mph or more. Here is the latest from the NHC as of 5PM EST:
Irma has become an impressive hurricane with intense eyewall convection surrounding a small eye. Satellite estimates continue to rapidly rise, and the Dvorak classifications from both TAFB & SAB support an initial wind speed of 100 kt. This is a remarkable 50-kt increase from yesterday at this time.
Irma continues moving west-northwestward, now at about 10 kt. There has been no change to the forecast philosophy, with the hurricane likely to turn westward and west-southwestward over the next few days due to a building ridge over the central Atlantic. At long range, however, model guidance is not in good agreement on the strength of the ridge, resulting in some significant north-south differences in the global models. I am inclined to stay on the southwestern side of the model guidance, given the rather consistent forecasts of the ECMWF and its ensemble. In addition, the strongest members of the recent ensembles are on the southern side on the consensus, giving some confidence in that approach.
