Thursday, August 15th 2019, 11:53 am - Colorado's record breaking hail serves as a reminder of how easily hailstorms can turn deadly.
Monster hail fell across the central United States earlier this week with a nearly five inch monster hailstone setting a new record for Colorado.
The hailstone, with an unofficial measurement of 4.83 inches in diameter and a weight of 8.5 ounces, fell in Bethune, Colorado on Tuesday afternoon.
@NWSBoulder @NWSGoodland I am verifying what looks to be a record setting hailstone for #cowx Am told this fell near Bethune this afternoon. Would easily beat the 4.5" record... Given the way the radar looked, I wouldn't be surprised. Stay tuned! pic.twitter.com/LiUazILn6r

The record was then confirmed by the Colorado Climate Center and the National Weather Service office in Goodland, Kansas on Wednesday as it beat out the previous state record of 4.5 inches for hail.
According to the state's Climate Center, the hailstone may have actually been even larger as there was 30 minutes between the time it fell and then put in the freezer.

There can be a tendency to underestimate the destructive power of a hailstorm because, for many people, hailstones get no larger than marbles -- a nuisance if you’re caught out in them, but not likely to do much of a number on your home or vehicle.
It's important to take hailstorms seriously.
2010: RECORD 8 INCH HAIL SLAMS SOUTH DAKOTA
To people in Vivian, South Dakota, it must have seemed like a divine rebuke when, in July 2010, a storm pummelled their community with massive hailstones, with the largest specimen reaching 20 cm across, or about 8 inches -- the largest on record.
That’s about as long as eight loonies side-by-side. Take a moment to just picture that in your head.
The largest hailstone on record, reaching 20 cm across, fell in Vivian, South Dakota, in July 2010. NWS Aberdeen.
Though underrated compared to more famous thunderstorm impacts such as tornadoes and lightning, people who live in places prone to the strongest thunderstorms know that, if the conditions are right, hail can be large enough to cause catastrophic damage -- and even kill.

SOME SERIOUS CANADIAN HAIL, TOO
Though the U.S. is no stranger to extreme hail, Canada also has some serious hailstorm chops.
The Edmonton Tornado of 1987 was part of a storm that produced hail as large as tennis balls, according to later surveys.
Hail that size is heavy. The heaviest-recorded Canadian hailstone fell at Cedoux, Saskatchewan, in 1973, weighing in at 290 g, or about 0.6 pounds. That pales in comparison to one stone that fell near Coffeyville, Kansas, that weighed in at 770 g, or about 1.7 pounds.
But those stones are driveway pebbles compared to one measured in Bangladesh in 1986, which was an enormous 1 kilogram, or 2.25 pounds. That massive stone was part of a monstrous storm that lashed the country’s Gopalganj district. Most chillingly, aside from the damage, this storm is also notable for killing 92 people.
WHEN HAIL KILLS
People in North America, where hail fatalities are relatively rare, might greet that incredible death toll with some skepticism. But hailstorms can absolutely kill when the hail is large enough, and the human cost can be staggering.
The deadliest-known hailstorm lashed the Indian city of Moradabad in 1888, dropping hail the size of oranges. By the time the storm had moved on, 246 people lay dead.
When we’re talking about meteorological history-makers, most writers take care to add the caveat “on record.” It’s a recognition that when it comes to the weather, there may be even more staggering weather extremes in Earth’s long history either unseen by human eyes, or not written down for posterity.
WATCH BELOW: CONTROL THE SIZE OF HAIL? ONE CANADIAN COMPANY SAYS 'YES'
And, in some cases, a particular storm may have been missed simply because it left no survivors.
It would be hard to imagine what went through the mind of a certain British forest ranger in Roopkund, India, when he happened upon some 200 skeletons clustered in and around a frozen lake at 16,000 feet above sea level.
That was in 1942, and the gruesome discovery went unexplained for decades, until a research team examined the site in the early 21st Century. Aside from establishing the massacre happened around 850 C.E., the victims were found to have died from repeated blows from “blunt, round objects about the size of cricket balls” (According to Atlas Obscura) -- just the kind of size hail would need to be to kill or seriously injure a human being.
The idea of hail large enough to kill you is frightening but, in North America at least, such major hailstorms are statistically less likely to result in fatalities.
No, when hail storms strike, the fear is less the potential loss of life, than it is the extreme and costly property damage.
HAIL DAMAGE COSTS BILLIONS EACH YEAR
Canada doesn’t get anything like the levels of confirmed tornadoes as the U.S. as a whole, but it is still one of the world’s most thunderstorm-prone nations, and when those storms produce damaging hail, there’s usually a hefty price tag attached.
