As Easter approaches, many people in Switzerland are gearing up for a trip south, drawn by the promise of sunnier days and warmer temperatures. However, this year, the weather forecast tells a different story. According to MeteoNews, moisture is building up in southern Switzerland, with significant rainfall expected just in time for Good Friday on April 18, 2025.
The unusual weather pattern is attributed to a trough extending over Western Europe combined with a high-pressure area in the Black Sea region. This combination creates a southerly flow that results in moisture accumulating on the southern slopes of the Alps. "Heavy rainfall is the result," the weather service reported on Tuesday, April 15, 2025.
By Good Friday, Ticino is expected to see between 100 and 150 millimeters of rain. In particularly affected areas such as Centovalli, Locarnese, Maggia- and Verzascatal, and Bedretto, precipitation could reach between 150 to 250 millimeters. The southern Valais region is also bracing for heavy rainfall, with the snow line dropping to 1000 meters. Above 2000 meters, forecasts predict 1 to 2 meters of new snow, significantly increasing the risk of avalanches.
In response to the severe weather conditions, the Federal Office for Meteorology and Climatology has issued the highest warning level 5 for the Upper Saastal and the southern Simplon region. The federal government is warning of an extreme rise in water levels of rivers and lakes, leading to potential flooding. Local authorities advise avoiding riverbanks and steep slopes, with warnings in effect until Thursday, April 17, 2025.
Travelers heading to Ticino for Easter should prepare for wet conditions, bringing raincoats and waterproof gear. In contrast, some models predict even heavier rainfall in parts of northern Italy, specifically the Aosta Valley and Piedmont, where estimates suggest 300 to over 400 millimeters of rain could fall.
On the other hand, the weather looks more favorable for central and eastern Switzerland, where the foehn wind is expected to keep conditions dry on Wednesday, April 16, 2025. Northeastern Austria and southwestern Germany are also likely to remain dry until Good Friday.
Looking ahead to the Easter weekend, forecasts remain uncertain. While Good Friday may provide a brief respite from the rain, models indicate that another moisture-laden system could develop, potentially bringing more rain to the same regions shortly after.
In light of the current weather patterns, Meteo Schweiz warns residents and travelers alike to stay vigilant. The weather service has forecasted heavy thunderstorms could occur in western Switzerland on Tuesday, April 15, 2025, from 4 p.m. to about 10 p.m., with potential for high lightning activity and heavy rain.
As the situation develops, the government emphasizes the importance of adhering to safety recommendations, particularly for those in high-risk areas. The warning for danger level 5 includes advice to avoid flood-prone areas and to stay clear of mountain streams due to the risk of sudden debris flows, which can occur without warning and possess significant destructive potential.
In the most affected areas, between Tuesday and Thursday, April 17, 2025, rainfall could accumulate to between 120 and 200 millimeters, leading to potentially hazardous conditions in the high mountains where up to two meters of new snow is anticipated.
As the weather unfolds, it remains crucial for those traveling for the Easter holiday to stay informed and prepared. While many may be looking forward to a sunny getaway, the reality of this year's weather may require some adjustments to travel plans.
In conclusion, the Easter holiday in Switzerland will be marked by significant weather challenges, particularly in the southern regions, as heavy rains and snowfall are set to impact travel and outdoor activities. Travelers are advised to monitor weather updates closely and take necessary precautions when venturing into affected areas.
