screatching Alternator?

I got a low pitch screatching at idle and low rpms (may be at higher ones too but I cant hear it over the engine) sounds like it is coming from the alternator...or something in that area. Is that consistant with an alternator going...if so how much time do I have left. I am not getting any dimming of lights..and it starts easy...then again this is a new noise. Any Ideas?

Serpentine belt need replacing? How many miles on it? That would be my guess, but....I might be wrong.

MJ,remove the belt and spin the altenator pulley by hand to see if will squeal any at all. If not,remove it and take it to a parts store to let them spin it over.Also,check your other pulleys and tensioner. It could also be just a belt like Brian said.
