![]() Hailstorm hit the town of Garciaz in Extremadura province, southwestern Spain, with hailstones up to 7 cm in diameter. Extensive damage to cars and trees was reported from the town of Pleven. Very large hail hit several villages and towns within a 120 km long path tracking through the districts of Vraza and Pleven in northwestern Bulgaria with hailstones up to 7 cm in diameter. Very large hail was recorded in the districts of Lendava, Murska Sobota, Gornja Radgona and Ljutomer in northeastern Slovenia, with hailstones up to 6 cm in diameter. An isolated supercell cut a 220 km long hailswath across the regions of Mazowieckie and Podlaskie in northeastern Poland with hail up to 5 cm in diameter. Colour of dots represents the maximum observed hail diameter with each event. Environments of damaging hailstorms over Europe in 2018 (dots) compared to the relative frequency of hail > 5 cm (colour bar) as a function of CAPE and 0-6 km bulk shear based on Pucik et al (2015). The hail swath on that day ( 40 km ) was much shorter compared to long-lived hailstorms of 1 May in Poland ( 220 km ) or the hailstorm of 30 June in southern Russia ( 200 km ).įig. The largest hail size was observed on 8 June 2018, when the town of Črnomelj, Slovenia was hit by giant hail up to 12 cm in diameter, destroying hundreds of roofs and cars. The spatial distributions of these major hail events and associated hail sizes can be found in in Fig. Each year there are a number of such events when hail of this size occurs across Europe and this year, 2018, was no exception.īy looking at the ESWD dataset, we found 26 days, when hail exceeded 5 cm and caused significant damage to the properties. Hail damage to properties, such as cars, roofs and windows, becomes substantial when the diameter of hailstones approaches and exceeds 5 cm. Report by Munich RE shows that damage of individual events can exceed billions of dollars as the risk has increased in the past decades. Severe hailstorms can cause extensive economic damage to both crops and properties.
