Central and Western Europe Will Experience Severe Wind and Rainfall
From October 22 to 25, influenced by the eastward movement of an upper-level cold vortex, countries including Ireland, southern UK, Portugal, northern Spain, the Netherlands, Belgium, France, southern Norway, southern Sweden, western Germany, Switzerland, northern Italy, Austria, Slovenia, eastern Czech Republic, Slovakia, northern Hungary, western Croatia, western Bosnia and Herzegovina, Montenegro, and Albania will experience severe wind and rainfall from west to east. These regions will see moderate to heavy rain, with some areas experiencing torrential rain and localized extremely heavy rain. Specifically, high-altitude areas in southern Norway, southern Switzerland, and southern Austria will face heavy to blizzard conditions, with localized severe blizzards (Figure 1). The cumulative precipitation during this period is expected to reach 20~40 mm, with some areas receiving 50~70 mm and localized areas exceeding 100 mm (Figure 2). This will be accompanied by strong winds of 5~6 levels, with gusts reaching 7~8 levels and locally up to 9~10 levels (Figure 3). Additionally, some regions will experience a temperature drop of 6~8°C, with localized drops exceeding 10°C (Figure 4). Precautions are needed to mitigate the adverse impacts of the severe wind, rainfall, snowfall, and cooling weather on local power transmission, shipping, and transportation.
