Well in my opinion:
Pressure difference = 1/2 x Air Density x Air Speed^2(squared)
So as the ambient pressure decreases the wind speeds pick due the generation of a pressure difference (the force that started the storm). This pressure difference also causes the water level to rise since the pressure on the water surface is lower than before, storm surge.
So i would recon that Wind speed is proportional to storm surge.
The wind speed would be the wind vector... I think.

In order for a significant storm surge to impact a coastline, the wind vector must be directed towards the coast, to blow water inland. If the wind vector is directed offshore, water levels will lower as the wind blows the water out to sea.

The wind has to be blowing toward the shore in order to cause the surge. But, it doesn't have to be blowing perpendicular to the shore. As long as the velocity vector of the wind has a component that is toward the shore, some surge will occur.
The greatest surge will occur when the vector is perp to the shore.
