2013 Tyrolean floods: mudflows, water, rain, flood, hail. Day by day. The damage caused the recent disaster in Tyrol 2013 and especially in the Tirol Unterland /lowland/ and area of Vorarlberg are incredibly large. For example, in Kössen / North Tyrol/losses due to flooding are over 100 million euros!

Spring and summer flooding in Central Europe is commonly associated with the so-called "Zugstrasse Vb" track of low pressure areas, which bring low pressure and moist air from the Mediterranean Sea over Central Europe, and have led to severe flooding in the affected region before. Low pressure areas "Frederik" and "Günther" formed over the northern Adriatic and tracked north towards central Europe. The high pressure "Sabine" and low pressure areas brought an airflow from the north across Germany, which brought the water-laden air from the north east. The air mass was pushed to the south west by the northerly flow, where it was lifted as it moved south from the North European Plain over the Thuringian Forest, Ore Mountains, and Bohemian Forest. The air was then lifted along the north side of the Alps in Austria as the air masses were pushed into the Alps by the northerly flow, which led to intense orographic precipitation. Heavy rain was reported in the Austrian states of Vorarlberg and Tyrol and the area of Salzburg, and to the mountains of Upper Austria and Lower Austria and Upper Styria in a short time.
On 30 May to 1 June, 150 to 200 mm of rain (5.9 to 7.9 in of rain) fell, in places reaching around 250 mm (9.8 in), which in just a few days was the equivalent normally seen over two and a half months on average. The rainfall experienced in Austria has an expected return period of between 30 and 70 years. The bulk of the rain fell in only two days in Salzburg, Tyrol, and Vorarlberg, which is thought to have a return period of more than 100 years.
