Latest RMS HWind Track Probability Analysis: Irma Shifts Further South and West Than Previous Forecasts

23:30 UTC  Thursday, September 7

Michael Kozar, senior modeler – Model Development, RMS

The RMS HWind team based in Tallahassee have released their latest track probability analysis of the current model forecasts. This analysis, based on forecast models initialized at 12:00 UTC today Thursday, shows that Irma’s projected path has shifted further south and west than the previous forecasts. The highest probabilities now run through southeastern Florida (as shown by the shaded data), with Miami having a nearly 60 percent chance of the storm passing within 50 nautical miles of the city.
