Hurricane Irma though weakening some overnight to 155 mph is expected to remain a Category 4 until landfall in south Florida on Sunday, remaining a strong hurricane.
Irma is undergoing an eyewall replacement cycle and this may cause some initial weakening before a reintensification when it is complete. Over the next 36 to 48 hours the environment will remain favorable for the hurricane with warm water and low shear.
The National Hurricane Center has the path of Irma moving up the center of the peninsula near Lakeland on Monday with winds to 105 mph, but there is still some uncertainty in the models that could affect the intensity of the storm.
A couple of the models are showing a track that would take it near or over Cuba and that would weaken the hurricane before it made landfall in Florida.
