1 Hailstones are ice lumps in different sizes - as peas, cricket balls or even up to 44,5 cm across.
2 Hail is formed when rain drops start to fall but before they reach the ground they are blown by wind several times up and down into the clouds.
3 By the time they travel up and down the cold clouds they are getting more and more covered with ice.
4 When hailstones are too havy to stay in the clouds they fall down causing a lot of noise and damage.
5 Buildings , cars , plants and crops are usually damaged , also driving during hailstorm is extremely dangerous
