How Big A Sailboat Can I Handle

Genoa brings deep Bisensturm, lots of snow and a muddy hut Nordföhn

The current, nameless Genoa has deep in the night to day and even during the day provided for interesting weather.

once again has become a classic counter-current situation. It flows into the lower layers of cold air north of the Alps. In the same height rule southerly winds that bring mild moist air to the Alps. The warmer air from the Mediterranean now glides on to the north lies heavy cold air and is raised - it caused large-scale precipitation zones (see diagram below). The large pressure differences provided also in western Switzerland, the Alps and in the south for a lot of wind

snow.
Although it was cloudy and gray in many places, above about 800 meters, but has clearly dominated the color white. Thus, in the mountains in the past 24 hours spread 15 to 30 cm fresh snow fell, sometimes it was cm to 40:

the morning I was in the range of Ibergeregg / SZ , 1406m on the road (all photos are from this region). As so often takes a massive amount of snow within a few 100 meters. In Oberiberg / SZ, 1080m of the SLF is an observer in the morning 14 cm snow measured. At 1400 meters is already 30 to 40 cm of fine powder. Directly on the pass and on the ridges but blew a gusty north wind. This led to some drifts, the temperature was about -3 degrees.

was then but the wind still an issue. The Bise was as expected on Lake Geneva, the most (because of the channeling between the Jura and the Alps) - were recorded gusts of 90 mph. On the Jura chain and the high alpine wind gusts reaching at times over 100 km / h. In Ticino and southern valleys of the Grisons Nordföhn blew with peaks of 60 to 90 km / h.

Despite North wind here but it was cloudy all day. The lower air layers were dried but, above about 2500 meters, the depth of Genoa but was responsible for all day moisture supply from the southeast - at times even making it rain. A similar effect is sometimes also called for Südföhn and Dimmerföhn. Whether this phenomenon has on the Southern Alps and a name, but I do not know.
