Wilma seems to be on a rapid intensification phase. Look at the satellite image below. You can clearly see the small eye developing and the intense convection surrounding the eye. To my knowledge I have never seen a hurricane with such an intense cdo. Katrina and Rita never even had one this intense in their early stages.
