Should npm global install in AppData\Roaming?

I am trying to install Jade globally using npm so that I can use the Jade watcher in WebStorm.

npm install jade --global

However, I can only find jade.cmd in:

...\AppData\Roaming\npm

and

...\AppData\Roaming\npm\node_modules\jade-watch\node_modules\.bin\jade.cmd

This doesn't seem right... shouldn't there be an entry under Program Files I can reference?
