In Valais and Chablais Vaudois, the population will not be able to walk this weekend on the banks of the Rhône and side rivers due to the risk of flooding. This ban applies from Friday until Monday evening.
The flow of the Rhône, currently at a high level, should continue to increase until reaching its peak on Friday late afternoon or evening, the Valais cantonal conduct body (OCC) indicated on Friday, reactivated for the ‘occasion. Overflows and debris flows can also occur on side watercourses.
In addition to avoiding the banks, the OCC recommends that the population not park on bridges, limit their movements – do not drive by car or bicycle on flooded roads – and refrain from filming or photographing events. . The AlertSwiss application includes these recommendations for Valais and Chablais Vaudois.
Since Thursday, a new alert has been issued for the Rhône with a marked degree of danger (3), from the mouth of the Lonza in Steg to Lake Geneva, we can read on the MétéoSuisse website. While a rain-storm front has been crossing Switzerland since Thursday, the soils are waterlogged after the rains that fell in recent days. And the snowpack is melting quickly these days.
Torrential wash near Zermatt
Still in Valais, “on Friday at dawn, torrential lava poured onto the road between Zermatt and Täsch, in an area where traffic is only possible with authorization”, Vincent Pellissier told Keystone-ATS , head of the Valais roads department. Accessibility to Zermatt is “as usual”.
Generally speaking, several incidents have been reported on cantonal roads due to waterlogged terrain, melting snow and precipitation. “These are micro-events, like stones on the road, which are quickly removed,” he added.
