In the last few hours, Hurricane Irma has become a little less organized with the eye becoming cloud filled and the pressure rising. But it will remain a strong hurricane. Irma will be going through internal eyewall replacement cycles causing fluctuation in the intensity, but it is going to remain a strong Category 5 or 4 hurricane as its environment will be favorable over the next 3 days with warm water and low shear.
Preparations for the hurricane should be completed before tropical storm force winds arrive in Florida in less than 48 hours.
Tropical storm force winds could be seen as early as 2 am Saturday morning in South Florida with the outer bands of Irma and then move up the I-4 corridor Saturday evening and on to north Florida by Sunday morning."
