European storms cause insured losses in hundreds of millions, says Aon

Investing.com -- Aon (NYSE:AON), a leading global professional services firm, has estimated that the severe convective storm activity across Europe between May 31 and June 4 will likely result in aggregate insured losses in the hundreds of millions of euros. The report was part of Aon’s weekly catastrophe recap.

The severe weather, which included large hail, strong winds, and localized heavy rainfall, affected several countries across Western and Central Europe in the given timeframe. The storms were generated by atmospheric conditions that led to violent storm development along a stagnant frontal boundary.

The storms first occurred in France, Germany, and the Netherlands and later expanded to Austria and the Czech Republic on June 1. The same day, a severe storm struck the eastern part of France’s Puy-de-Dôme department, impacting the municipalities of Olliergues, Vertolaye, Bertignat-Job-Marat, Tours-sur-Meymont, and Saint-Gervais.

Reports indicate that the storm caused property and agricultural damage in these areas, with thousands of customers experiencing power outages. Following the initial storms, additional storms between June 3 and 4 caused severe local effects in Slovenia, Hungary, and Poland.

The hailstorm in France accounted for the majority of economic and insured losses. Aon estimates that aggregate losses from multiple severe convective storm outbreaks are likely to be in the hundreds of millions of euros. This estimation is pending future damage assessments in the affected countries.
