Lee is now up to 105 mph maximum sustained winds, but is on its way to a Cat 5:

From the NHC: "The question doesn't appear to be if RI continues, but rather how strong Lee will get, and how quickly will it get there. Many of the models are calling for remarkable rates of intensification, beyond rates normally seen with model forecasts. Both HAFS models forecast Lee to exceed 150 kt within the next 2 days, and even HCCA brings the hurricane above the category 5 threshold. The NHC intensity forecast has been shifted significantly higher, but is actually within the guidance envelope. It should be stressed that internal dynamics (eyewall replacement cycles) will become a factor with the maximum strength of Lee as it becomes a major hurricane. This is almost certain to lead to fluctuations in intensity that are beyond our ability to forecast at these lead times."
