Fig. 1 The maximum sustained wind predicted for Hurricane Isabel (2003) by the decay model using information contained in the last operational TPC/NHC advisory prior to landfall (1500 UTC 18 September) (a) and using the landfall intensity and storm positions obtained from the TPC/NHC post-storm analysis (b). The solid white lines show the track used to create each swath. The maximum winds adjusted to 10-m and an averaging time of 1-min are also depicted. The contour interval is 15 kt.
