Hail

Hail forms when updrafts in thunderclouds carry raindrops upward into extremely cold areas and freeze layer upon layer until they are too heavy and fall to the ground. Hailstones vary in size from peas to grapefruits and fall at great speed. Hailstones have seriously injured people. 

What To Do When It Hails

1. Take cover when hail begins to fall.
2. Do not go out to cover plants, cars or garden furniture or to rescue animals.
