Storm Boris has brought a mix of extreme weather to Europe, from heavy rain and flooding to the first snow of autumn, according to an analysis using Solcast API. The low pressure system, named Boris by the Italian Meteorological Service, unleashed record rainfall across Central Europe, while the UK and parts of the Alps saw their first snowfall. The situation is stabilising as the system weakens and a high pressure area takes hold over the region.

Central Europe suffered severe flooding from Storm Boris, which brought record levels of precipitation in some regions. The convergence of cold Arctic air with warmer air masses from the Mediterranean and the Caspian Sea caused persistent rain and snowfall across the region. A part of the low pressure system was trapped over the Adriatic, forming a slow-moving secondary system that prolonged the rainfall, causing several days of downpours. In some areas, rain fell for months in just a few days, straining local infrastructure and prompting severe weather warnings in several countries.

As the storm spread across Europe, snow began to fall in some regions for the first time this season. In the UK, Arctic winds cooled temperatures enough for peaks in Scotland to see their first snowfall since the summer. Alpine regions in Italy and Austria also saw early snowfall, particularly at higher altitudes where rain from Storm Boris turned into heavy snowfall.

Conditions across Europe are currently less severe as Storm Boris has moved south-east of Italy. The system has weakened since passing through Italy but has continued to cause flooding and evacuations. Forecasts call for a brief respite from the rain in the coming days before more precipitation in Central Europe next week.
