My serpentine belt keeps shredding and popping off in the rain

What is your question?

A few days ago my serpentine belt was all shredded and it popped off all of the pulleys while driving in the rain, but three days after I replaced it, it became shredded again and popped off, in the rain. + Whenever I use my air conditioner or heating, a weird noise comes from the front of the car. (I've checked the oil, the power steering fluid, they're all full). I want to know if it's the rain, or it's one of the pulleys (+ which pulley) that make it happen
