Hail suppression is an uncertain meteorological subject in premature agricultural servitude. Commonly known is the method of seeding menacing cumulonimbus clouds with silver iodide by means of rockets or aircraft flares.

The state of the art of hail formation detection with radar, and of hailfall probability nowcasting, is briefly reviewed.
