Air conditioning leak on 2009 Buick Lucerne

Apparently my ac drain is leaking into my passenger side rear floor board. Really a lot of water. Any ideas?

Yes, the drain hose is plugged up, it is under the right hand side of the vehicle just under the passenger floor area. I usually take a coat hanger and then use the wire to make a stiff tool to unblock the drain hose.
thanks a bunch. I'm going to do that at first light!
