Bracing for Intense Winter Weather: A Precarious Pre-Christmas Period
Northern regions are gearing up for some of the most challenging pre-Christmas days in recent decades, if not centuries. The weather will take a turn for the worse, starting with high pressure system "Fiona" offering a brief respite.
The Stormy Carousel
The low pressure system "Xavi" is shifting from Iceland to Scandinavia, causing congestion in the Scandinavian mountains. This leads to snowfall and drifts due to strong winds. Meanwhile, the Azores High, a powerful opponent, and the jet stream intensifying the lows further, creating a mixed situation and increasing the risk of storms across a wide area.
Consequences of the Stormy Weather
Heavy gales to gale-force gusts of around or over 100 km/h may hit, causing potential damage at Christmas markets. The old and the young are especially vulnerable to these extreme winds. The coastline of Germany and surrounding countries are also at risk with a threat of storm surges and renewed worsening of the flood situation due to heavy rainfall in some places.
The Storm Timetable
The wind will increase from the north over the next few days, especially on Thursday and Friday. The next few days will see the wind gradual increase from the north, reaching gale-force gusts of around or over 100 km/h.
Preparedness and Caution
As our forests are no longer leafy, the focus shifts to the Christmas markets, where damage could be substantial. We must remain vigilant and keep an eye on wind warnings from the mid-week. The heaviest storms are expected in mountainous areas and at sea, where storm surges pose a threat.
The Flood Situation
Comparatively, the southern half of Germany has been less affected by the melted snow. However, the northern half of the country, particularly sensitive areas, faces a tense flood situation due to the heavy rainfall, aggravated by the saturated soil.
The Weather Forecast
The weather predictions are uncertain, showing wild variations in temperatures. Climate records may be broken, while others may see mild air or even snowfall by the calendar date for the start of winter. The situation is turbulent, allowing for plenty of unexpected surprises.
Extreme Weather Events: A Global Concern
Extreme weather events during the festive season have become increasingly common worldwide. In some cases, these events involve hurricane depressions like the one in northern Europe and the Baltic Sea, as described, leading to significant impacts in various regions.
