Storms

A 7 in (178) hailstone weighing 1.5 lb (680 g) is believed to be the record largest known in the U.S. a the time

A violent forty-minute hailstorm bombed Fort Collins, CO, with hail up to grapefruit size.   Two thousand homes and 2500 automobiles were severely damaged, and about 25 people were injured, mainly when hi ton the head by the huge stones.

A thunderstorm caused $342 million worth of insurable damage in Calgary.  Thirteen additional hailstorms between 1981 and 1998 caused an estimated $600 million in damage in the Calgary area alone.

$572 million. Golf ball, baseball, and softball sized hail damaged roofs, cars, patio furniture, skylights, and windows in the area's worst and most widespread hailstorm in 30 years (McHenry, Lake, northern Kane, northern Cook County). Around 100,000 homes lost power.  Hail was 3 in (76 mm) deep in many areas.  There were 100 canceled flights, and train service was disrupted.

A storm, with hailstones approximately the size of golf balls, battered Calgary for 10 minutes.  A subsequent storm 2 days later brought in another round of hailstorm with high winds causing additional damage to the city.  The cost of these events reached $552 million.

Regarded as the hailstorm capital of Canada, a massive hailstorm of tennis-ball-sized pummeled northeastern Calgary and nearby communities.  Preliminary damage estimates weigh in at least $1.2 billion, eclipsing the $400 million hailstorm event 10 years prior and becoming the 4th costliest natural disaster in Canada.
