Why do mobile / internet signals get disturbed when it rains?

I have observed it . When it rains , there is distortion in both mobile and internet signals. Mobile / internet signals we use are through wireless communications.

They make use of electro - magnetic waves to send signals through long distances. Rain attenuation is a problem in wireless communications . Rain , fog , ice crystals , snow all will absorb some of the signals , they can also scatter the waves.

This causes drop in the strength of signal or attenuation . 

Because of this , we experiance disturbance when receiving the signals when it is raining.
