Hail can also undergo "dry growth", in which the latent heat release through freezing is not enough to keep the outer layer in a liquid state. Hail forming in this manner appears opaque due to small air bubbles that become trapped in the stone during rapid freezing. These bubbles coalesce and escape during the "wet growth" mode, and the ...
Severe is defined as hail 1 to 2 inches (25 to 51 mm) diameter, winds 58 to 75 miles per hour (93 to 121 km/h), or a tornado. [11] Significant severe is defined as hail 2 inches (51 mm) in diameter or larger, winds 75 mph (65 knots, 120 km/h) or more, or a tornado of strength EF2 or stronger. [1] [12]
In Canada, a severe thunderstorm is defined as having wind gusts of greater than 90 km/h (56 mph), hail with a diameter of greater than two centimetres (0.79 in), rainfall rates of greater than 50 millimetres (2.0 in) in one hour or greater than 75 millimetres (3.0 in) in three hours, or tornadoes.

So far, the world-record hailstone was found in Bangladesh in 1986, weighing in at just over 2 pounds. ... Hail: How hailstones form and why they're destructive. Hail is an increasingly expensive ...
Iowa is at risk of numerous severe storms including large hail, damaging winds and possibly tornadoes from 3 p.m. to 11 p.m. Tuesday.
In recent days Central Florida has become ground zero to severe storms bringing destructive hail and damaging winds.
The storm is also believed to have spawned several tornadoes, and the exact size of the hail that fell within it is unknown. The overall damage was so great that an entire new insurance company, The General Hail Insurance Company, was formed to help cope with future hailstorms. This company would later be known as the Norwich Union. [45]
Hail is one of the most significant thunderstorm hazards to aircraft. When hail stones exceed 13 millimetres (0.5 in) in diameter, planes can be seriously damaged within seconds. [68] The hailstones accumulating on the ground can also be hazardous to landing aircraft. Wheat, corn, soybeans, and tobacco are the most sensitive crops to hail ...
