Hi Sam. You can achieve a certain rain effect by putting a cylindrical
object in front of your view point and moving it anytime the view point
moves. You can apply an alpha texture with the rain drops to the object
and move the texture coordinates. The result is quite nice (depending on
the quality of the texture and the movement of the texture coords). Also
you can apply a fog effect to make it more realistic.

I'd be happy of hearing about other alternatives.
