Hail accumulation on route E-21 in La Cruz, Cordoba, Argentina
An intense hailstorm hit the Cordoba region of Argentina on Thursday, October 26, 2017 leaving hail accumulations of 1.5 m (4.9 feet) within 15 minutes around La Cruz reported La Nacion.

Meteorologists issued alerts before the storm hit but they 'never' imagined such an impressive phenomenon said Fire Chief Martin Bustos. Firefighters worked for several hours with two diggers to free cars trapped on route E-21 and to make the road passable.

Also in Argentina, on the previous day (Wednesday, 25 October, 2017) giant hailstones of up to eight centimeters in diameter hit Formosa damaging more than 1,000 buildings.

A couple of weeks ago (Sunday, October 8, 2017) giant hail damaged cars as a freak hailstorm hit Corrientes and surrounding areas.

Some other severe hailstorms from around the world in recent months include: It is likely that atmospheric dust loading from increased comet and volcanic activity is contributing to these 'intense' or 'freak' hailstorms, the cooling effect of which causes ice crystals to form.
