What should I major in to complement an Applied Atmospheric Science major?

I plan on majoring in Applied Atmospheric Science in college. My ultimate goal is to go to graduate school (possibly at University of Miami's RSMAS) and obtain my masters (and possibly phd) in meteorology/atmospheric science/oceanography. I want to work for either the National Weather Service in a forecasting office, headquarters, or at the National Hurricane Center, or a University after I obtain my graduate degrees. The problem is I do not know what I should minor in during undergrad. I have narrowed it to either: coastal and marine studies, computer science, geology, hispanic studies, or math. I really want to learn to speak Spanish fluently (it would especially be helpful in Miami) so that is my first choice, but I know Coastal and Marine Studies, Math, or Computer Science would be more helpful in my career and competitive for graduate admissions. Which should I do?
