Severe weather has struck northern Italy and southern Switzerland, prompting national weather services to issue a red weather alert due to extreme rainfall. This alarming situation unfolded on April 16, 2025, and is expected to continue into April 17, 2025, as a powerful low-pressure system over the Gulf of Genoa pushes unusually moist air against the southern flank of the Alps. The result? Torrential rains and heavy snowfall that threaten to wreak havoc in these regions.
In the southern parts of the Swiss Alps, particularly in the western Tessin and southeastern Wallis, meteorologists predict that up to 200 millimeters of precipitation could fall locally within just 48 hours. Above 2,200 meters, the forecast is even more daunting, with expectations of over two meters of snow. These conditions have led to the closure of the Great St Bernard Tunnel between Switzerland and Italy for heavy truck traffic due to heavy snowfall.
The storm is particularly devastating in northern Italy, where regions such as Piedmont, Lombardy, and the Aosta Valley are bracing for up to 350 millimeters of rain. Flooding and landslides are already causing significant disruption, with major highways and roads closed. Train services on the Simplon line, which connects Italy and Switzerland, have also been suspended due to the severe weather.
Local authorities are on high alert as the water level of the Po River rises rapidly, with predictions that it will reach critical levels within the next 24 to 36 hours. Additionally, waves as high as three meters are expected along the Italian coast in the Mediterranean Sea, further complicating the situation.
As the storm continues to unleash its fury, two individuals were rescued from a vehicle that had been swept into a river near Turin. This incident underscores the dangerous conditions that residents and tourists alike are facing in the affected areas.
Weather warnings are not limited to heavy rainfall; orange alerts for thunderstorms are also in effect in Piedmont and the French department of Savoie. The combination of extreme weather phenomena has created a precarious situation for many, especially those vacationing in the Alps during the Easter holiday.
Jos Mark, a camping enthusiast who travels with his wife and dog, has been caught in the midst of this chaos. "We were looking forward to a relaxing holiday in the Alps, but now it feels like a survival scenario," he said. Campers are being urged to secure their tents against strong winds and rising waters, as many campsites are at risk of flooding.
In higher altitude areas, avalanche warnings have been issued due to the heavy snowfall and strong winds, creating a hazardous environment for both tourists and locals. The Swiss broadcasting corporation has advised against venturing into the mountains and navigating steep slopes. The snow line is fluctuating between 2,500 and 1,800 meters and may drop even lower in certain areas.
For those currently camping in the region or planning to head there soon, experts recommend several safety measures. First, choosing a safe campsite is crucial. If you're located in a valley or near a river, it may be wise to relocate to higher ground to avoid potential flooding. Second, having an evacuation bag ready with essentials like dry clothing, medications, a flashlight, water, and snacks is advisable. Lastly, staying updated on weather conditions is vital. Utilizing weather apps and following local news channels can provide critical information as the situation evolves.
As the weather begins to stabilize from Good Friday, April 18, 2025, it remains uncertain how long the disruptions will last. The unpredictable weather over the coming days could still impact travel plans and outdoor activities, particularly for winter sports enthusiasts.
In summary, the extreme weather affecting northern Italy and southern Switzerland serves as a stark reminder of nature's unpredictability. With heavy rainfall, significant snowfall, and rising water levels, residents and tourists must remain vigilant and heed the warnings of local authorities to ensure their safety during this tumultuous period.
