How to protect crops and property from hail

Damage to vineyards following several years of severe hailstorms in the famed wine-growing region of Burgundy, France, is prompting greater prevention efforts.

London’s Daily Telegraph reports that producers are protecting their entire grape harvest with a cloud-seeding system—a hi-tech hail shield that is designed to modify storm clouds and suppress hail formation.

The system works by releasing tiny particles of silver iodide into the clouds where they stop the formation of hail stones, thereby reducing the risk of damage.

Cloud-seeding, or weather modification, has been used for many years in parts of the United States and Canada not just to suppress hail, but to enhance rainfall and snowfall in some cases. Insurers are involved in the research.

This makes sense. According to the National Oceanic Atmospheric Administration, hail causes approximately $1 billion in damage to crops and property annually.

A monster hailstorm that pounded Colorado’s Front Range on May 8 is on pace to be Colorado’s most expensive insured catastrophe, with an estimated preliminary insured loss of $1.4 billion, according to the Rocky Mountain Insurance Information Association.

For auto, home and business owners living in hail-prone areas, taking steps to minimize hail damage to property is essential.

The Insurance Institute for Business and Home Safety (IBHS), is continuing a major multi-year research study into hailstorms. IBHS resources on preventing property losses are available here.
