Floods have brought chaos to a large swathe of central Switzerland, triggering landslides and cutting roads and railway lines.
The Swiss capital did not escape the severe weather
At least six people are reported dead or missing, including two firefighters killed by a mudslide on Monday.
Floods halted rail services through the Alps towards Italy and several major roads were closed and villages cut off.
Floods have also hit towns in Austria and southern Germany and continue to affect Bulgaria and Romania.
The area affected in Switzerland stretches from the Bernese Alps to St Gallen in the north-east.
Torrential rain has lashed Switzerland for nearly three days, hampering efforts to clear debris and shore up flood defences.
Over 1,000 people have been evacuated.
Electricity was cut off and water contaminated as a consequence of inundation.
Shipping on part of the River Rhine - flowing into France and Germany - was also halted after the water level rose.
Alpine resorts hit
About 400 people were evacuated in the village of Ibach in canton Schwyz after the River Muota burst its banks.
The River Luetschine also flooded an area near Wilderswil and the Alpine resorts of Grindelwald and Lauterbrunnen were cut off.
Parts of the resort of Interlaken were also flooded and 150 people - many of them tourists - spent the night in civil defence facilities, the Swiss Info website reported.
There are fears that the swollen river Aare could cause even more damage in Interlaken and the capital, Bern, where 300 people had to be evacuated from a flooded residential area.
Swiss officials say the situation also remains critical around the swollen lakes of Thun, Brienz and Biel.
