- Hail
A hail stone is a lump of ice which forms during a thunderstorm when water droplets have been tossed high into the freezing reaches of cumulonimbus or thunder clouds. In Canada, hail stones generally range from the size of peas to the size of oranges but have been as large as 114 millimetres or the size of a grapefruit.
