"It probably got funneled, intensified, by the entrance to the channel. We can analyze it later when there’s more evidence. It might have diffracted around the Hook, bounced off the Maasvlakte dike, picked up steam as the channel narrowed. You can’t predict this sort of thing, sadly, but doing the postmortem is easy. Like you can’t predict a car crash but it’s easy to reconstruct it from skid marks."
