South Dakota Storm Produces Record Hailstone

NOAA’s National Climate Extremes Committee, responsible for validating national weather records, has declared a hailstone found last week in Vivian, S.D., to be the largest in diameter and heaviest ever recovered in the United States.

Found after a July 23, 2010, severe thunderstorm by Vivian resident Les Scott, the hailstone is 8.0 inches in diameter and weighs 1.9375 pounds (1 pound, 15 ounces) with a circumference of 18.62 inches.

These measurements displace the previous hailstone record for weight, previously 1.67 pounds for a stone in Coffeyville, Kan., in 1970. They also surpass the record for diameter, which was 7 inches for a hailstone found in Aurora, Neb., in 2003. The Aurora hailstone still holds the record for circumference of 18.75 inches.

“I’m just glad nobody got hurt and hope the town will recover soon,” Scott said.
8 inch sind ca. 20 cm (Durchmesser), der Umfang sind umgerechnet ca. 47 cm!
