The curve normal flips when its direction crosses the y axis. Creating the curve lying down and rotating it up afterwards doesnt help either. What I use to do with curves that are driving a motion or flow object is, before you create the curve, create a Nurbs plane and model it as a ground shape for the curve to lie on. Make the Nurbs-mesh Live and create the curve on it. Now the curve will draw its normals from the Nurbs mesh and it won't flip. Just shape the Nurbs-mesh when you want to alter the curve's shape.
