The National Oceanic and Atmospheric Administration (NOAA) has been promoting the fact it “nailed” Irene’s track four days out. Their home page features a satellite animation following the National Hurricane Center (NHC) track issued at 11 p.m. ET on Tuesday, August 23.
You have heard me say this before. Four days out, the average tropical forecast error is 200 miles. So that makes this forecast verification even more amazing!! Check out the video: NOAA Environmental Visualization Laboratory - NOAA Accurately Predicted Irene's Path 4 Days in Advance
