![]() This hailstorm lasted for 40 minutes and contained hailstones up to grapefruit size. Hailstones with a circumference up to 23 cm caused widespread destruction, including the breaking of 12,000 large windows in the Iscor plant area and damaging hundreds of cars in the plant. Many of the most severe injuries were sustained by people celebrating the holiday on the beaches without any shelter nearby. Some of the hailstones were as large as coconuts.Īt the time, it was the most severe storm to strike the city since recorded observations began in 1792. (In the same weather event, at least nine people were killed in flooding.) This hailstorms killed ten people and several head of cattle. Some of the hailstones were reportedly as large as oranges. In some locations, the layer of hailstones was 60 cm thick. This hailstorms killed at least 230 people, and over 1600 sheep and goats. Afterwards, the General Hail Insurance Company was formed. In some locations, the hailstone layer was 1.5 meters thick. Midlands and East Anglia, Central and Southern England Hail caused severe damage to crops, furthering the lack of food that precipitated the French Revolution. The event, which took place during the Hundred Years War, became known as Black Monday. This hailstorm killed approximately one thousand English soldiers. This explanation is supported not only by investigations of the remains, but also by local legends and songs about the event. Researchers have concluded that the skeletons are the remains of a large group of pilgrims who were killed by a hail storm at this high altitude glacial lake in the 9th century. Hundreds of human skeletons have been found in and around Lake Rookund, giving it the nickname Skeletons Lake. This hailstone fell in Bangladesh’s Gopalganj District on 14 April 1986. This hailstone fell in Aurora, Nebraska, USA on 22 June 2003. This hailstone fell in Vivian, South Dakota, USA on 23 July 2010. Cheyenne is the hailest city in Hail Alley, with an average of 9-10 hailstorms per year. A majority of all hailstorms here occur in the afternoon and evening. In the United States, the most hail-prone area is where the states Colorado, Nebraska and Wyoming meet. ![]() In Europe, Croatia, Serbia, southern and western Germany, eastern Benelux, and northern and eastern France are examples of hailstorm hot-spots. Not only are hailstorms fairly frequent here they also tend to cause a lot of damage. Hailstorm Alley runs from High River northward through Calgary, through Red Deer to Lacombe and then westward to Rocky Mountain House. The mountainous parts of China also experience serious hailstorms comparatively often.Ĭanada’s Hailstorm Alley is located downwind of the Rocky Mountains, in south and central Alberta. Northern India, which is a very mountainous region, is renowned for its frequent and often severe hailstorms. There is also less time for formed hailstones to melt before they reach the surface of the Earth. ![]() Hail is more common along mountain ranges, because horizontal winds that hit the mountains side are forced to move upwards, and when this happens to a thundercloud it will intensify the updrafts that are already present within it. During its record-breaking year, it experienced hailstorms on 132 days of the year. On average, Kericho experiences hailstorms on 50 days per year. It is Kericho, which is located in Kenya, close to the equator and at an elevation of 7,200 feet / circa 2195 meters. Still, the “hailest” place on Earth is in the tropics (but at a high elevation). Where?Įven though thunderstorms are much more common in the tropics than in the rest of the world, hail is actually more rare in the tropics – especially at lower elevations. Hail can be produced within 2 nautical miles (3.7 km) of the parent storm. Hail is thus associated with electrical storms, but that doesn’t mean that we always find ourselves in a thunderstorm just because its hailing. The cloud type responsible for producing hail is the cumulonimbus cloud, i.e. Each such ball or lump is called a hailstone and measures at least 5 millimeters in diameter. Hail is a form of precipitation consisting of balls of ice or irregular lumps of ice.
