  • Avalanches: no danger
  • Earthquakes: may be perceptible
  • Floods: transport disruption and damage are not normally to be expected.
  • Forest fires: small fires cannot be entirely ruled out
  • Meteorological phenomena: no (particular) danger, no warnings in place
Danger level 2 (Moderate danger)

Explanation of the danger level 2:

  • Avalanches: very little danger
  • Earthquakes: felt across a wide area, no likelihood of damage to buildings
  • Floods: rivers are unlikely to burst their banks and floods are unlikely but not impossible
  • Forest fires: local fires can start spontaneously
  • Meteorological phenomena  that are normal for the respective season
Danger level 3 (Considerable danger)

Explanation of the danger level 3:

  • Avalanches: exposed objects (mostly sections of transportation routes) can be endangered
  • Earthquakes: felt across a wide area, likelihood of minor damage to buildings
  • Floods: rivers may burst their banks locally in exposed places and flooding may occur.
  • Forest fires: surface fires are likely
  • Meteorological phenomena of an intensity slightly superior to the normal
Danger level 4 (High danger)

Explanation of the danger level 4:

  • Avalanches: exposed objects (mostly sections of transportation routes, but in isolated cases also buildings) can be endangered
  • Earthquakes: felt strongly, likelihood of damage to buildings
  • Floods: rivers may increasingly burst their banks and flooding may occur
  • Forest fires: surface fires are very likely
  • Meteorological phenomena of unusual intensity
Danger level 5 (Very high danger)

Explanation of the danger level 5:

  • Avalanches: transportation routes and settlements can be seriously endangered
  • Earthquakes: felt strongly, high likelihood of widespread and severe damage to buildings
  • Floods: rivers may burst their banks and flooding may occur in many places
  • Forest fires: fires can start at any time
  • Meteorological phenomena of very high intensity

Obey in any event the orders issued by your local authorities and be prepared for exceptional measures.

Nächste Information: Sonntag, 27. September 2020 11:00 Uhr

Starker Schneefall am Alpennordhang 

Zwischen Freitagmorgen und Sonntagmorgen werden am Alpennordhang oberhalb von 1800 Metern starke Schneefälle von 50 bis 90 cm erwartet. 
Prozess Stufe Betroffene Gebiete von bis
Schnee 3 Alpennordhang 25.09.20, 06 Uhr 27.09.20, 06 Uhr

Wetter  (Stand: 26.09.2020, 11:00 Uhr)

Aktuelle Situation

Eine Tiefdruckrinne erstreckt sich von Ostdeutschland bis nach Oberitalien. Die Schweiz liegt an deren Westflanke in einer kräftigen Nordwestströmung, welche feuchte Polarluft zu den Alpen führt. Damit hat sich am Alpennordhang eine Nordstaulage eingestellt.  Bis heute Samstagmorgen sind am Alpennordhang vom Urnerland ostwärts über das Glarnerland bis zum Säntisgebiet sowie im Chablais Niedeschlagsmengen von 30 bis 60 mm gefallen. Die Schneefallgrenze lag gestern bereits am frühen Morgen bei etwa 1500 Metern und sank bis gestern Abend auf etwa 1100 Meter ab. Oberhalb von 1200 Meten sind bisher 10 bis 30 cm, oberhalb von 1800 Metern 30 bis 60 cm gefallen.

Prognose

Die erwähnte Nordstaulage dauert noch bis Sonntagmorgen an. Dabei sind am zentralen und östlichen Alpennordhang nochmals 30 bis 50 mm, am westlichen Alpennordhang 15 bis 30 mm Niederschlag zu erwarten. Die Schneefallgrenze liegt dabei im Bereich von 1000 bis 1200 Metern. Damit sind oberhalb von 1400 Metern nochmals 10 bis 20 cm, am zentralen und östlichen Alpennnordhang örtlich auch über 30 bis 50 cm Neuschnee zu erwarten.
