These estimates support an initial intensity of 125 kt, making Norman a category 4 hurricane on the Saffir-Simpson Hurricane Wind Scale. As a result of the increased initial intensity, the NHC intensity forecast has been adjusted upward through 36 h, but it is otherwise unchanged. There has been no change to the NHC track forecast.
