Climate stations and authorities additionally issued warnings a number of hours earlier than the storm hit the Maggia Valley and the Leventina on Saturday night.

They later recovered a 3rd physique.
The ladies have been apparently trapped in a landslide. The search continues to be on for a lacking individual within the Val Lavizzara, one among two valleys that ultimately be part of the Maggia Valley.

After heavy rain and storm, the Maggia partially overflowed its banks. Pictured right here: destroyed homes in Mogno.
Cassis guarantees federal assist
As in Misox, southern Graubünden, final Sunday, Federal Councillor Ignazio Cassis now additionally appeared earlier than the media in Ticino. “It is vitally unhappy to be taught of the pure disasters that claimed so many lives on two consecutive Sundays,” Cassis stated.
Based on Cassis, the federal authorities is supporting the Ticino canton as a lot as doable. A military Puma helicopter was already in motion on Sunday morning. Amongst different issues, 4 Rega helicopters with two extra arrived within the Maggia valley within the afternoon to evacuate 300 remoted individuals: 200 locals needed to depart their properties, one other 100 individuals attended a sports activities occasion in Prato Sornico throughout the storm.
The Wisłetło street bridge was destroyed by water.
The water dashing into the Maggia destroyed the Vizelleto Bridge in Savio, which was important for the city. The Swiss military is now investigating how they will construct a short lived street bridge to reconnect the higher Maggia valley with the decrease valley. The realm round Savio and within the Lavizzara valley nonetheless has neither electrical energy nor clear consuming water. As SRF reviews on Monday morning, citing the Ticino police, work is ongoing to revive the facility provide. In Fuzio and Piano di Peccia within the Lavizzara valley and in San Carlo within the Bavona valley, three factors have been arrange for communication with the skin world in case of emergencies.
The mayor of Lavizzara stated in a press convention on Sunday afternoon that he by no means believed his eyes would see such devastation. He nonetheless doesn’t know the best way to give a future to the affected villages.
However threats just like the weekend’s storm to the Maggia Valley are well-known to space residents.
This isn’t the primary landslide in Bawan Valley
When numerous rain falls inside a brief time frame within the Maggia Valley, many streams and rivers rise dangerously quick and steep slopes grow to be slippery. As well as, the danger of robust storms is especially excessive within the southern a part of the Alps. In Ticino, heavy rain fell for a number of months. The shortage of rain for nearly a 12 months has triggered the groundwater degree to fall quickly, inflicting an enormous quantity of runoff.
The soils are actually oversaturated. They’re changing into unable to soak up extra water. As well as, resulting from international warming, the permafrost is disappearing within the excessive mountain areas, which suggests much more water is polluting the slopes. The slopes start to slide, as occurred within the Bavona Valley and every week in the past in Misox.
An knowledgeable within the space says there have already been landslides within the Bavona Valley. The person needs to stay nameless. He says a particles circulation close to Faido in August 1992 killed a lady and her son and cut up the village in two. A protecting mound was later constructed from the landslide materials to forestall additional accidents. And, he provides: After a storm in 1987, the Bavona River overflowed its banks and severely broken the one street by the facet valley. As well as, particles flows swept away the world, which thankfully didn’t kill anybody.
The person says, “It’s popularly stated that you must depart Bawan Valley when there may be heavy rain.”
Cantonal geologist Stefano Daverio assesses the scenario equally. Within the occasion of heavy rainfall, the Maggia valley is a typical space the place the danger of storms and disasters will increase. That is significantly true for the Bavona facet valley: the cliffs within the valley are extraordinarily steep and the water circulation paths are brief and violent. The chance of landslides will increase with moist slopes as nicely. Already final December, the residents of the valley have been requested to depart the world.
Based on police commander Antonio Ciocco, head of the regional disaster crew, the three weekend victims have been discovered exterior their vacation village, the home buried underneath rubble and dust. Ciocco says the three vacationers apparently knew nothing about warnings from authorities.
Pure disasters are on the rise within the Southern Alps. Based on Ciocco, the scenario raises the query of whether or not the warning system must be reconsidered at a nationwide degree.
Federal Councillor Cassis says he additionally noticed warning messages for the Maggia Valley on his cellular phone. Nonetheless, his impression is that individuals take into account the warnings to be exaggerated. It’s a delicate consideration how clearly and comprehensively the authorities ought to warn individuals. The warnings should not trigger panic, Cassis stated.
Rescue staff, police and civil safety say that landslides are virtually by no means predictable. Tidal waves in Maggia, which might be generated by violent storms, are extra predictable: sudden intense rainfall fills the varied reservoirs within the mountains of the Maggia valley. To keep away from a dam break, operators need to launch water for a short while into the streams that feed into Maggia.
The Swiss Military’s Tremendous Puma helicopters are additionally in use in Ticino.
The sudden launch of water may cause tidal waves, which have killed many individuals previously. The largest influence was on vacationers who have been bathing and have been shocked to see the water.
