Sleet is raindrops which freeze into ice pellets before hitting the ground.
It usually bounces off of surfaces that it hits and does not stick to things. It can, however, accumulate like snow. This can be dangerous, especially to drivers on the road. Freezing Rain Freezing rain is rain which falls onto a surface which has a temperature below freezing. The rain then freezes when it hits the surface, such as a road, because the temperature of the surface is less than 32 degrees Fahrenheit.
