Europe was hit by severe winter weather and flooding in early January 2026, as an Arctic cold wave combined with intense rainfall episodes to produce fatalities, infrastructure disruption, and significant economic damage, according to a catastrophe assessment published by Aon.

Between January 4 and January 9, Western and Central Europe experienced temperatures 10–15°C below seasonal averages, accompanied by heavy snowfall and freezing rain, while Southern and Southeastern Europe faced torrential rainfall, flash floods, and snowmelt-related flooding. The events resulted in at least seven fatalities and economic losses estimated in the tens of millions of euros, with assessments still ongoing.

France, Germany, the UK, the Benelux countries, and parts of Central Europe were affected by winter-related accidents and transport disruptions, while southern Spain, Italy, and the Balkans reported evacuations and emergency responses due to flooding. In Spain’s Málaga Province, rainfall totals reached up to 200 mm in some areas, triggering red flood alerts.

Insurance market perspective

For insurers, the events once again underline the material loss potential of winter perils, particularly from snow load, freezing conditions, and water damage. While insured losses are expected to represent only a portion of total economic damage, the clustering of winter weather and flooding highlights ongoing protection gaps, especially in flood-prone regions of Southern and Southeastern Europe.

From a reinsurance standpoint, the early-January events reinforce concerns over loss volatility outside traditional peak catastrophe seasons, increasing the relevance of secondary perils in European portfolios. As winter hazards become more frequent and geographically diverse, insurers are likely to place greater emphasis on risk prevention measures, coverage clarity, and portfolio diversification, alongside continued investment in catastrophe modeling for winter-related risks.

Weather conditions across Europe remain unstable in mid-January 2026, with forecasts indicating that winter hazards are likely to persist in the near term. Northern and Central Europe continue to be affected by below-average temperatures, snow, and icy conditions, while parts of Western and Southern Europe face renewed rainfall episodes.

What to expect for the next weeks

As cold air lingers over large parts of the continent, the risk of flooding remains elevated, particularly in areas where rainfall overlaps with melting snow. This is especially relevant for Western Europe and parts of Southern and Southeastern Europe, where soils are already saturated following recent storms and river levels remain high.

Overall, meteorological models suggest that adverse winter weather is likely to continue episodically, rather than as a single prolonged event. While not all regions will be equally affected, the combination of cold spells, snowmelt, and heavy precipitation means that local flooding and weather-related disruptions remain a credible risk across Europe in the coming days.
