Authorities report that thunderstorms and heavy rain have caused flooding in Switzerland near Basel, Geneva, and the canton of Vaud on Lake Geneva.

On Tuesday evening, police in the canton south of Basel received several hundred reports of flooded basements, power outages and other water damage.

By Wednesday, the situation had calmed down.

In the western canton of Vaud, the fire department was called out more than 200 times.

According to the police, the river in the town of Moges reached flood levels that are statistically not expected even once every hundred years.

No injuries were reported.

In Geneva, severe thunderstorms and heavy rain led to a two-hour suspension of flight operations.

A cooling room for servers in the Skyguide air traffic control building was affected by flooding.

To prevent overheating of the control systems, the airspace was closed shortly after 10:00 p.m.

Around 50 arrivals and departures were cancelled.

Around 100 passengers were provided with overnight camp beds and food. On Wednesday, departures were cancelled for planes that could not land on Tuesday evening.

However, a Geneva airport spokesman said no major damage occurred, and operations went back to normal.

Last week, a landslide after heavy rainfall swept away three houses in the eastern canton of Graubünden and destroyed part of the A13 motorway, an important route through the Alps.

Of the four missing people, one woman was rescued, and a man was found dead. The other two individuals remain missing.
