The type of information you seek is not available to my knowledge.  While this information maybe obtained based on past El Ninos, no two events provide exactly the same impacts across the United States.  The National Center for Environmental Information has a webpage that provides information based on the 6 strongest El Ninos, which may be of interest to you.
