I haven't found any information on that topic and its homepage doesn't mention it.

Even though planned, at the moment there is no support for Python 3, you can check it out more details about that reading this thread from the storm ml:

That was before the 0.14 release and a long time ago, any changes since that?

Since january i've not heard anything about the porting; at the moment if you try to install storm package v.0.14 with Python 3.0.1 the process fails while building a C extension. I didn't investigate how much effort is needed to fix that error.
