The expected rains have occurred and it is raining now in some places has been almost 24 hours.The moist warm Atlantic air that builds up from the northwest to the Alps, provides in part for rain rates up to 8 mm / h (Kössen).

precipitation values 24 - hour (Wednesday 18z - Thursday 18 z) in liters per square meter
Kössen (T) 124.3

Bad Aussee (St) 65.7
fell in Vorarlberg way up to 42 mm (Bregenz) and the UBIMET / OeBB station in just 50 Dalaas mm.Zudem engages in exposed positions of the stormy northwest wind is, gusts of up 137 km / h on Feuerkogel are the logical consequence.
Who has the expected rainfall of the models of yesterday in the head provides that in particular the EC from the Maximalmenegen ago was clearly next to it (maximum 50 mm). The UKMO and GFS were reliable in this case.
keyword flooding
in Upper Austria (Innviertel) and Salzburg (Wallersee, Thalgau, Salzach, Mitterberghütten) in the morning are überflutetete Keller and meadows have been reported on the A1 at Thalgau was aquaplaning reported and several streets in Salzburg (range Wallersee) were closed due to flooding.
The problem in this case, the combination of heavy rain, with the still frozen (and sometimes snow covered) soils dar.Das water is not absorbed by the ground (such as in summer) and runs off the surface.

Keywords river level
Since the morning is the marked increase in Flußpegel observed (especially in Upper Austria). The largest tributaries of the Danube River Traun, Steyr and Enns wait Wasserstandsmessugnen increased to - the high-water marks are still not achieved. The Amounts of water from the fallen precipitation is also still the melt water to the existing snow cover and the fact was that the snow line during the day 1600-2000 m, has not helped to ease the situation.
Here are some selected water level data from gauging stations in Upper Austria. Some may be regulation by the opening of the locks (Steyr), or closing of the locks (Gmunden: decreases Traun level - sea level rises) guess

A word of avalanche
 |
| Nightly snowfall was ver of the day in rain over - here at 1940 m in Obergurgl (total 12mm) |
is permanently heavy rain as in the past 24 hours, the snow does not absorb more water and the water runs through. On this greasy film and on the steep grassy slopes of the snow slides off - there is snowslides The dangerous is the mass of such a fabulous avalanche.. 10 m³ snow (4x5x0, 5m) weigh in at a density of 600 kg / m³ after only 6 tons and a rather small "Lawinchen.
Rudi Mair from the avalanche warning service in Tyrol leads the present report provides expert from Tyrol Today, nachzuschaun in orf-ondemand, also comes from the small sample calculation.
A paragraph on Streif
The continuing rain from the start (Ehrenbachhöhe at 1650 m with Dauerregn by +2 degrees) to the target area (Kitzbühel to 745 m in rain and +4 degrees) as specified by the Chief of course does not have any serious impact on the status of the runway. She was soaked and at temperatures below freezing in the best condition. In the night of Saturday, the temperature in the entire range area just below 0 at night and on Sunday a second time - at least in the basin. By the approach of High will develop a stable layer, keeping the temperatures expected above freezing. By no later than the middle of next week, the freezing temperatures are again dominant - thus should technically pure piste happen.
