The island begins to impact a cyclonic system as soon as the system’s outer edge makes contact with it. If it is going to shear its interior it’s going to shear its outer reaches alike. There is no magic, no difference. It’s an immovable land form that denies any air mass that would like to be in its place. Simple as that. To say it doesn’t affect until some point later in the storm’s passage is just nonsense. It’s not some kind of woo woo, it’s plane and simple physics. Land form, air mass, interaction.
To say the interaction is greater the deeper into the cyclonic system the land form is, sure. But to say it has no impact until some moment beyond the first contact is ridiculous. Air mass, land form, interaction. The air cannot pass through the land and as such has to go elsewhere. Around, over, but not through. And, the air that goes over gets dragged down by its interaction with the land. On the storm's outer reaches there's less of an effect, for sure, it's in contact with a smaller portion of the storm, but still an effect.
We can imagine other things.. like the air between the land form and the center of the system being compressed by the forward motion of the system, and that compressed air pushing back onto the center and as such nudging, steering, it one way or another. We can talk about the wobble set in motion when the shearing begins and becoming greater over time, and the closer the center of the air mass gets. There’s all sorts of stuff to ‘model’ when we consider how the land/air interaction develops, but the interaction starts the moment the air makes contact. Seriously, Fiend, how could it be otherwise?
You do remember the Butterfly effect yeah?
