Danger level 1 (No or minor danger)
Explanation of the danger level 1:
- Earthquakes: may be perceptible
- Meteorological phenomena: no (particular) danger, no warnings in place
- Floods: transport disruption and damage are not normally to be expected.
- Avalanches: generally safe conditions
- Forest fires: small fires cannot be entirely ruled out
Danger level 2 (Moderate danger)
Explanation of the danger level 2:
- Earthquakes: felt across a wide area, no likelihood of damage to buildings
- Meteorological phenomena that are normal for the respective season
- Floods: rivers are unlikely to burst their banks and floods are unlikely but not impossible
- Avalanches: low danger of natural avalanches
- Forest fires: local fires can start spontaneously
Danger level 3 (Considerable danger)
Explanation of the danger level 3:
- Earthquakes: felt across a wide area, likelihood of minor damage to buildings
- Meteorological phenomena of an intensity slightly superior to the normal
- Floods: rivers may burst their banks locally in exposed places and flooding may occur.
- Avalanches: isolated exposed sectors are endangered. Some safety measures recommended in those places.
- Forest fires: surface fires are likely
Danger level 4 (High danger)
Explanation of the danger level 4:
- Earthquakes: felt strongly, likelihood of damage to buildings
- Meteorological phenomena of unusual intensity
- Floods: rivers may increasingly burst their banks and flooding may occur
- Avalanches: many exposed sectors are endangered. Safety measures recommended in those places.
- Forest fires: surface fires are very likely
Danger level 5 (Very high danger)
Explanation of the danger level 5:
- Earthquakes: felt strongly, high likelihood of widespread and severe damage to buildings
- Meteorological phenomena of very high intensity
- Floods: rivers may burst their banks and flooding may occur in many places
- Avalanches: acute danger. Comprehensive safety measures.

Natural hazard bulletin
Naturgefahrenbulletin des Bundes
Ausgabedatum: Dienstag, 27. Juni 2017 12:00 Uhr
Nächste Information: Mittwoch, 28. Juni 2017 12:00 Uhr
Intensive Niederschläge und Hochwassergefahr auf der Alpensüdseite und in den angrenzenden Regionen
Auf der Alpensüdseite und in den Alpenhauptkamm angrenzenden Regionen sind intensive Regenfälle zu erwarten. Ticino, Maggia, Lago Maggiore und Lago di Lugano werden am Mittwoch die Hochwasser-Gefahrenstufe 2 erreichen.
| Prozess | Stufe | Betroffene Gebiete | von | bis |

| Hochwasser | 2 | Lago Maggiore, Lago di Lugano, Maggia, Rhone , Ticino , Tresa, Urner Reuss | 28.06.17, 00 Uhr | 30.06.17, 12 Uhr |
Wetter
Aktuelle Situation
Mit einer starken südwestlichen Höhenströmung auf der Vorderseite eines Tiefs über dem Ärmelkanal überquert am Mittwoch eine aktive Störungszone mit kräftigen, teils gewittrigen Regenfällen die Schweiz.
Prognose
Am Alpensüdhang ergiebige Regenfälle, möglicherweise mit eingelagerter stationärer Gewitterlinie, besonders in den Regionen Maggiatal, Verzasca und in der Leventina. Die intensiven Niederschläge können mit den starken Südwestwinden in der Höhe auch die nördlich dem Alpenhauptkamm angrenzenden Regionen erfassen. Die intensivste Phase ist am Mittwochvormittag zu erwarten. Daher ist eine Warnung Stufe 3 aktiv, mit Niederschlagsmengen von 100-130 mm für die Alpensüdseite, Maggiatal, Verzasca und Leventina 150-200 mm. Es ist nicht ausgeschlossen, dass in der Leventina lokal die Stufe 4 (130-160 mm) erreicht wird. Die Schneefallgrenze liegt zunächst oberhalb 3000 m und sinkt in der Nacht auf Donnerstag gegen 2500 m. In den nördlich des Alpenhauptkamm angrenzenden Regionen sind 50-80 mm zu erwarten (Stufe 3), und weiter im Norden 30-50 mm (Stufe 2).
Fliessgewässer und Seen
Aktuelle Situation
Die Flüsse auf der Alpensüdseite, am Alpennordhang, im Graubünden und Wallis haben auf die seit Montagnachmittag gefallenen Niederschläge mit moderaten Abflussanstiegen reagiert. In den alpinen Einzugsgebieten, insbesondere im Wallis, sind die Abflüsse aufgrund der intensiven Schnee- und Gletscherschmelze erhöht. Der Wasserstand des Lago di Lugano ist am Sonntag aufgrund der ergiebigen Gewitter rasch angestiegen und liegt am Dienstagmittag nur noch 7 cm unterhalb dem Schwellenwert zur Gefahrenstufe 2.
Prognose
Aufgrund der vorhergesagten gewittrigen Niederschläge werden die Abflüsse von Maggia und Ticino stark ansteigen und voraussichtlich am Mittwochvormittag die Gefahrenstufe 2 erreichen. Die Spitzen werden gegen Mittwochabend erwartet. Insbesondere beim Ticino ist auch ein Ansteigen in die Gefahrenstufe 3 möglich. Die erhöhten Zuflüsse führen zu einem Anstieg der Wasserstände des Lago Maggiore und des Lago di Lugano. Das Überschreiten der Schwellenwerte zur Gefahrenstufe 2 wird an beiden Seen für Mittwoch vorhergesagt. Die Höchststände der Seen werden am Donnerstag erwartet. Der Pegel des Lago di Lugano könnte sogar die Gefahrenstufe 3 erreichen. Die Abflüsse der Urner Reuss und der Rhone werden mit den prognostizierten Niederschlägen und in Kombination mit der Schnee- und Gletscherschmelze ebenfalls stark zunehmen. Sie werden wahrscheinlich die Gefahrenstufe 2 knapp erreichen.
Auch die kleinen und mittelgrossen Flüsse im Tessin, Wallis, Graubünden und am Alpennordhang werden stark ansteigen. Die Flüsse in der Leventina werden wahrscheinlich am stärksten betroffen sein.
