Above is a link to a tutorial on how to create rain within Photoshop. It really helps in creating a moody effect onto the image:

 The technique describes using four layers selecting each one within a different frame.

This technique is also good for the waterfall and other ware effects. It is important to make sure layers are selected correctly within each frame.

It also cuts down the workload because I am able be only draw four frames in which creates a flowing movement.
