Windshield Wiper Arms and Snow Build-Up

Hi,

I have a question about windshield wiper arms and snow possibly damaging them. Every time it snows, I make sure to lift my front and rear wiper arms off the front and rear windshields, respectively. I was just wondering whether snow accumulating on the wiper blades and wiper arms in their lifted/raised position can put a damaging weight on the wiper arms, damaging some components of the wiper system?

Please let me know. Thanks.
