The 2019 Timaru hailstorm occurred in Timaru, in the Canterbury Region of New Zealand, on 20 November 2019. Lasting for about 10 minutes, it produced hailstones the size of golf balls and turned the streets white. It caused about $171 million in damage, mostly to cars, becoming one of New Zealand's costliest natural disasters. At the time of the event, it was the country's fifth costliest natural disaster since records began, and the costliest weather event in the 21st century. Cyclone Gabrielle surpassed the cost of the hailstorm in 2023, by a large margin.
The hailstorm started before the noon of 20 November 2019 [1] and lasted for about 10 minutes. [2] The hailstones were up to the size of golf balls [1] and caused the streets to become covered in "carpets of white". [2]
The hailstones caused widespread building damage throughout Timaru, and some businesses had to close for the day. Fire and Emergency New Zealand received 30 call outs from noon to 2.40 pm, 21 of which relating to hail or rain damage. The hail caused one person to go to hospital after a minor injury. [1]
About 8,000 to 12,000 cars were damaged in Timaru. [3] [4] This included dents, damage to mirrors, tail lights and spoilers, and smashed windscreens. [5] [2] This compromised the structural integrity of some of the cars, causing Warrants of Fitness to fail. [6] Insurance companies created a car repair shop in Washdyke and another in 'the south end of town', [2] and people came overseas from Australia and Brazil. [3] [7] [8] Timaru experienced a car shortage, and in the following year, new car registrations in the Timaru District had increased by 62.7 per cent. [2]
Hundreds of black-billed gulls and white-fronted terns had either died or been severely injured at the Rangitata River mouth. Several eggs had also broken. [2] Crops were damaged on a widespread scale. Farmers often do not insure their crops because they consider it 'expensive', although there is a compulsory levy on wheat that is used to protect the crops. [9]
The hail caused windows and glass houses to smash, roofs to become leaky, skylights to get damaged, [10] [11] and holes to appear in house guttering. [12] Timaru Boys' High School and Roncalli College had roof damage [1] and the cupolas and dome of Timaru's Sacred Heart Basilica experienced severe damage. Work to replace the copper tiling of them finished in August 2024. [13] [14]
Insurers paid out about $171 million, [14] which was more than the preliminary estimate of $83 million in March 2020. [15] Of this cost, $86.2 million (12,078 claims) related to motor vehicles, $59.6 million (5,791 claims) for 'house and contents', $23.2 million (1,047 claims) for 'commercial', $73,759 (15 claims) for 'marine', $171,701 (10 claims) for 'crops' and $1.7 million (99 claims) for 'other'. [2] [16] The cost was several thousand dollars for each person in Timaru. [17]
At the time of the event, it was fifth costliest natural disaster in New Zealand since the Insurance Council of New Zealand's records began in 1968. The only disasters that were more costly were the 2010 and 2011 Christchurch earthquakes, the 2016 Kaikōura earthquake, the 1987 Edgecumbe earthquake and the sinking of Wahine in 1968. It was also, at the time, the country's costliest weather event in the 21st century, [16] with the second costliest being the 2004 lower North Island storms, which cost $148 million. However, those storms covered a much greater area than the Timaru hailstorm. [17] The cost of the Timaru event was surpassed in 2023 by Cyclone Gabrielle by a large margin, the cost being in the billions. [18] [19]
Hail is a form of solid precipitation. It is distinct from ice pellets, though the two are often confused. It consists of balls or irregular lumps of ice, each of which is called a hailstone. Ice pellets generally fall in cold weather, while hail growth is greatly inhibited during low surface temperatures.
A supercell is a thunderstorm characterized by the presence of a mesocyclone, a deep, persistently rotating updraft. Due to this, these storms are sometimes referred to as rotating thunderstorms. Of the four classifications of thunderstorms, supercells are the overall least common and have the potential to be the most severe. Supercells are often isolated from other thunderstorms, and can dominate the local weather up to 32 kilometres (20 mi) away. They tend to last 2–4 hours.
Severe storms in Australia refers to the storms, including cyclones, which have caused severe damage in Australia.
Severe weather is any dangerous meteorological phenomenon with the potential to cause damage, serious social disruption, or loss of human life. These vary depending on the latitude, altitude, topography, and atmospheric conditions. High winds, hail, excessive precipitation, and wildfires are forms and effects, as are thunderstorms, downbursts, tornadoes, waterspouts, tropical cyclones, and extratropical cyclones. Regional and seasonal phenomena include blizzards (snowstorms), ice storms, and duststorms.
The tornado outbreak of April 10–11, 2001, was a large tornado outbreak which affected the central Great Plains on April 10–11, 2001. During the two-day outbreak, it produced a total of 79 tornadoes across eight states including Kansas, Missouri, Oklahoma, Texas, Nebraska, Iowa, Illinois and Michigan. Four people were killed, 18 injured, and more than $23 million in damage was reported. The fatalities were reported in Oklahoma, Iowa and Missouri including two from a single tornado in Wapello County, Iowa.
The 1999 Sydney hailstorm was the costliest natural disaster in Australian insurance history, causing extensive damage along the east coast of New South Wales. The storm developed south of Sydney on the afternoon of Wednesday, 14 April 1999, and struck the city's eastern suburbs, including the central business district, later that evening.
The 1947 Sydney hailstorm was a natural disaster which struck Sydney, Australia, on 1 January 1947. The storm cell developed on the morning of New Year's Day, a public holiday in Australia, over the Blue Mountains, hitting the city and dissipating east of Bondi in the mid-afternoon. At the time, it was the most severe storm to strike the city since recorded observations began in 1792.
The 1995 Mayfest storm was a damaging hailstorm that struck parts of the Dallas–Fort Worth metroplex on May 5, 1995. It was the first singular thunderstorm with a damage toll exceeding $1 billion and at the time the costliest nontornadic thunderstorm in U.S. history. Hail up to 4.5 in (11.5 cm) in diameter fell across Parker and Tarrant counties, producing hail drifts as deep as 3 ft (0.91 m) and damaging numerous buildings. The storm also struck the Fort Worth Mayfest – a local outdoor festival – pelting the roughly 10,000 people in attendance with softball-sized hail and resulting in over 60 hospitalizations. Though there were no hail-related fatalities, the combination of the slow-moving supercell that produced the hail and a larger complex of storms led to deadly flash flooding that killed 17 people in the Dallas area. Overall, 20 people were killed by the storms.
The 2010 Victorian storms were a series of storms that passed through much of the Australian state of Victoria on 6 and 7 March 2010. One of the most severe storms passed directly over Greater Melbourne, bringing lightning, flash flooding, very large hail and strong winds to the state's capital.
The 2010 Western Australian storms, also known as the "Storm of the Decade" were a series of storms that travelled over southwestern Western Australia on 21 and 22 March 2010. One of the more intense storm cells passed directly over the capital city of Perth between 3:30 pm and 5:00 pm on Monday 22 March 2010. As of 2024, it is still the costliest natural disaster in Western Australian history, with the damage bill estimated at A$1.08 billion.
On October 5–6, 2010, a destructive series of thunderstorms struck Arizona, resulting in the state's largest tornado outbreak and its costliest weather disaster on record. Spawned by a nearby cold-core low, successive hailstorms in Phoenix and surrounding locations on October 5 caused damage to thousands of homes, businesses, and vehicles. The following day, a record 12 tornadoes were recorded, multiple strong/EF2 or greater on the Enhanced Fujita scale and many in close proximity to one another; this included two tornadoes rated EF3. Thunderstorms on both days caused significant flash flooding which inundated businesses, stranded vehicles, and closed roadways. Damage throughout the state reached $4.9 billion, including $2.7 billion in insured loss from just hail damage, the costliest weather event on record in Arizona. Some impacts occurred in California, Nevada, and Utah as well as the cold-core remained stationary over several days.
On the morning of March 9, 2012, a long-lived hailstorm hit the Hawaiian islands of Oahu and Lanai. The hailstorm was produced by a supercell thunderstorm. This event produced the largest hailstone ever recorded in Hawaii since records began in 1950. The hailstone was measured at 4.25 in (10 cm) long, 2.25 in (6 cm) tall, and 2 in (5 cm) wide. National Weather Service meteorologist Tom Birchard stated that the event was "unprecedented."
The 2014 Brisbane hailstorm struck Brisbane, the capital city of Queensland, Australia on 27 November 2014. The storm caused severe damage to many buildings and cars in the city. Around 40 people were injured. Wind speeds of 141 km/h (88 mph) were recorded with multiple reports of hail in the city and surrounding areas.
Hailstorm Alley is a colloquial term referring to an area of south and central Alberta, Canada where hail storms are frequently produced. These storms frequently produce hail that is damaging to property. This area stretches from High River in southern Alberta, northward through Calgary, through Red Deer to Lacombe and then westward to Rocky Mountain House. It is known to be one of the worst areas in the world for damaging hail produced by thunderstorms. These are regarded as loose boundaries. While this area is common for damaging hailstorms, the reality is damaging hailstorms occur over much of central and southern Alberta every summer. The City of Calgary is regarded as the hailstorm capital of Canada.
The July 1968 United Kingdom thunderstorms were the most severe dust fall thunderstorms in the British Isles for over 200 years. A layer of mineral dust blowing north from the Sahara met cold, wet air over the British Isles, resulting in thick, dense clouds and severe thunderstorms across most of England and Wales. These clouds completely blotted out the light in some areas and the rain and hail resulted in property damage and flooding, and at least four people were killed. During the storm, Leeming Bar in North Yorkshire saw 35.7 millimetres (1.41 in) of rain in under 10 minutes – a UK record until 2003.
On May 15, 1697, a severe hailstorm tracked south-westwards between the towns of Hitchin (Hertfordshire) and Potton (Bedfordshire) in Southern England. The storm moved slowly, beginning at 9 am and finishing by 2 pm local time. The parent storm's total track length was at least 25 km (16 mi) long. This hailstorm is widely considered to be the worst hailstorm ever documented in the United Kingdom, with the largest hail ever measured in addition. Widespread damage to property was reported where the hailstorm had passed through, with slate roof tiles smashed to pieces and resulting in at least 1 death.
Beginning on Friday, 27 January 2023, regions across the upper North Island of New Zealand experienced widespread catastrophic floods caused by heavy rainfall, with Auckland being the most significantly affected as the Auckland Anniversary holiday weekend began.
