Storm Hendrik-Ignatz, also known as storm Aurore, which impacted parts of north-western and central Europe from October 20th to 21st, is expected to drive insurance industry losses of €311 million, according to an initial estimate by PERILS.

Storm Aurore was driven by an unusually strong jet stream for mid-October with wind speeds of up to 250km/h and is the first significant extratropical cyclone of the 2021/2022 European windstorm season.

According to PERILS, the majority of the initial insurance property market losses occurred in France, Germany, Belgium, and Luxembourg, with Switzerland and the Netherlands hit to a lesser extent.

PERILS’ loss estimate is based on claims data collected from the majority of the affected insurers.

The low-pressure systems associated with the event were named Hendrik and Ignatz by the Free University of Berlin, and it was named storm Aurore by the Meteo France.

The unusually strong jet stream drove “low-pressure system Hendrik and its marginal low Ignatz across the Irish Sea and as far as northern Russia within only a two-day period,” explains the firm.

“A horizontal pressure gradient towards the southeast coupled with a passing cold front resulted in strong surface winds which predominantly affected France, Belgium, Luxembourg, Germany, Poland and the Czech Republic.”

The Zurich-based provider of industry-wide catastrophe insurance data adds that while the wind field generated by the storm was extensive, gusts were not so extreme and rarely breached 120km/h in populated areas.

As a result, the insured loss was comparatively moderate and could be expected to be reached or exceeded at least once a year during the European windstorm season.
