| ABSTRACT | Extra-tropical cyclones dominate autumn and winter weather over western Europe and particularly over the Iberian Peninsula. Intense, high-impact storms are one of the major weather risks in the mid-latitudes. High winds and extreme precipitation from extratropical cyclones can result in windstorm damage, flooding and coastal storm surges, having large socioeconomic impacts. In Portugal, due to the extensive human use of coastal areas, the natural and built coastal environments have been amongst the most affected. In this paper a consistent catalogue of compound hydrometeorological extreme events over the Euro-Atlantic region is presented. Additionally reanalysis allow the assessment of the synoptic evolution, dynamical characteristics and the main impacts of the top-20 storms that provoked extreme impacts and considerable economical losses over Portugal.
