Eye of a storm

Why does the wind drop in the centre of a Hurricane?
At the centre of a hurricane the pressure is a minimum, so there is
no
pressure *gradient*, i.e. the pressure does not vary with distance.
Because
the wind is caused by the pressure gradient, there is little or no wind in
the
eye of the hurricane. The pressure gradient is a maximum just outside the
eye
wall, where the strongest winds are.

Does that mean then (showing my lack of knowledge here!) that once the eye
has passed over, instead of there being a slow increase in wind speed, it
goes from virtually nothing to the highest speed in a short time?
I imagine that's why they say that the worst is to come after the eye.
