A sudden return of winter weather has caused significant disruption across Switzerland, with heavy snowfall forcing the temporary closure of the Gotthard Tunnel and leading to widespread power outages in the Diemtigtal valley.

"The breakdown was probably caused by the snow and ice."
Switzerlandâs most critical transport link has succumbed to the elements. At precisely 7:00 PM on Thursday, authorities were forced to shutter the Gotthard Tunnel as a ferocious late-season blizzard rendered the A2 motorway impassable. This is no mere dusting; the northern slopes of the Alps are grappling with a staggering 10 to 30 centimeters of fresh snow, with local accumulations surging toward 40 centimeters. The closure instantly severed the primary north-south artery, leaving a trail of logistical wreckage in its wake. Between Wassen and GĂśschenen, heavy goods vehicles sit motionless, their transit halted by the sheer volume of precipitation. To the south, the situation is equally dire: a 2-kilometer wall of steel has formed between Quinto and Airolo. This sudden return of winter confronts a nation that was already eyeing the spring horizon, proving that the Gotthard remains at the mercy of the Alpine climate regardless of the calendar.
Over 1,000 households were plunged into darkness as the Diemtigtal valley became the epicenter of a widespread infrastructure failure. The power grid flickered and died at 5:52 AM, a casualty of the heavy snow and ice that weighed down lines across the Bernese Oberland. While engineers from BKW managed to restore power to Diemtigen within two hours, other municipalities remained isolated in the cold until mid-morning. It took nearly five hours of intensive labor to bring the entire valley back online by 10:30 AM. This outage highlights the persistent vulnerability of regional grids when faced with rapid, heavy snowfall. The weight of the 'white gold'âusually a blessing for tourismâtransformed into a mechanical burden that physically snapped the connection between these mountain communities and the modern world.
A dozen accidents in a single morning have turned the roads of St. Gallen into a graveyard of skidding vehicles and shattered glass. Police reports confirm that half of these incidents occurred on high-speed motorways, where drivers were blindsided by the sudden transition from wet asphalt to lethal ice. In Appenzell Outer Rhodes, the story was the same: vehicles spinning off carriageways and rear-end collisions becoming the morning norm. Remarkably, no injuries have been reported, but the sheer volume of accidents underscores a critical lapse in seasonal readiness. Further east, snowstorms swept through GraubĂźnden with such intensity that visibility plummeted to near zero. Meanwhile, the WSL Institute for Snow and Avalanche Research has issued a high-risk warning across the Alpine ridge, from Valais to Lake Walen. The mountains are currently a powder keg of unstable layers, threatening more than just the morning commute.
Switzerland is currently a nation of two clashing seasons. While the north battles blizzards and blackouts, Ticino is under an absolute ban on outdoor fires due to persistent drought and tinder-dry forest conditions. This dramatic contrast is set to intensify. Despite todayâs chaos, meteorologists are forecasting a meteoric rise in temperatures, with the Central Plateau expected to hit a balmy 16°C by Easter Sunday. The snow that today paralyzes the Gotthard will likely be a memory within 72 hours, replaced by spring sunshine. This volatilityâswinging from 40cm of snow to double-digit warmth in daysâis the new reality for Swiss infrastructure. As the snow trickles softly over the Central Plateau and melts upon impact with the 5°C ground, the nation prepares for a holiday weekend that promises to be as warm as the morning was frozen. The Gotthard will reopen, the lights will stay on, but the reminder of natureâs unpredictability remains etched in the day's traffic jams.
