We thank Chris Landsea and David Zelinsky of NHC for helpful reviews of the manuscript and assistance constructing several figures, as well as the HWRF teams at both the National Centers for Environmental Prediction (NCEP) Environmental Modeling Center (EMC) and the Hurricane Research Division (HRD) for providing very high temporal-resolution data from the HWRF model. The provocative comments of three anonymous reviewers significantly improved the manuscript. Airborne radar data were provided courtesy of the NOAA Hurricane Research Division of AOML in Miami, Florida. This work was supported by the NOAA Hurricane Forecast Improvement Program (HFIP).
