NORTH PLATTE, Neb.(KNOP) - Rime ice is an opaque, or milky white, deposit of ice. Meteorologists say it happens when water droplets in fog freeze to the outer surfaces of objects. It happens in the winter when low-hanging clouds cause freezing fog and sticks to things like the KNOP-TV tower.
Rime ice is different than hoar frost. Rime ice happens in freezing fog. Hoarfrost forms in the absence of fog.
