Japan is bracing for significant winter weather as the Japan Meteorological Agency warns of heavy snowfall and strong winds across various regions. Expected particularly on December 19, 2024, this storm is set to deliver the coldest air of the season, creating unstable atmospheric conditions throughout the country.
On December 19, a strong influx of cold air is anticipated to sweep through Shikoku, leading to not only snowfall but also potential rain across the Seto Inland Sea region. According to the Japan Meteorological Agency, "明日19日は、上空に今季一番の強い寒気が流れ込んで大気の状態が不安定になる見込みです" (Translation: "On the 19th, the strongest cold air of the season is expected to flow, causing unstable atmospheric conditions."). This situation presents various dangers, including road hazards as temperatures plummet.
Snow is likely during the morning hours, especially when temperatures are at their lowest. Reportedly, "特に気温の低い時間帯にあたる朝にかけては、雪の降る所が多くなる可能性があります" (Translation: "Especially during the morning hours when temperatures are low, there's the possibility of increased snowfall."). With predictions of up to 5 centimeters of snow on the northern Kyushu mountains, local governments are preparing for rapid road condition changes.
Meanwhile, concerns extend to coastal areas, particularly near the Tsushima Strait, where blizzard-like conditions and significant snow are expected. Local authorities have issued advisories stating, "明日19日未明から朝、九州北部の山沿いは大雪のおそれ" (Translation: "From early morning on the 19th, there is the fear of heavy snowfall along the northern Kyushu mountains."). Citizens are advised to remain indoors if possible or travel only when necessary.
Driving during snow events requires special precautions. The Japan Meteorological Agency suggests, "雪道で車を運転する場合は、スノータイヤを装着し、急ブレーキ、急なハンドル操作は避けましょう" (Translation: "When driving on snow-covered roads, please use snow tires and avoid sudden braking and sharp steering."). If you must travel, opt for winter tires, maintain extra distance from other vehicles, and stay updated with traffic weather advisories.
Looking beyond December 19, the weather outlook indicates fluctuated conditions as another low-pressure system will pass across Japan. From December 20 to 25, areas can expect improved weather as the cold front weakens. Nevertheless, the cold returns on December 22, with potential snow and rain affecting not only northern regions but also extending to the central and southern parts of Japan.
Following holiday traditions, some northerners may even score a white Christmas. With holidays approaching, many are hopeful for picturesque holiday scenes but must remain cautious. Local forecasts speculate, "近畿地方でホワイトクリスマスになるのは、北部や山沿いに限られそうです" (Translation: "It seems a White Christmas will be limited to northern areas and mountainous regions of Kinki.").
Preventative measures against common winter illnesses are also being circulated. People are advised to wear masks during outings, especially in crowded places, maintain hygiene, and adjust indoor humidity to between 50-60% to mitigate flu risks.
Japan’s residents are preparing to safeguard themselves and their families against the impending storm. The forecast predicts brief warming leading to difficult transition days where wet roads may freeze overnight. Therefore, it’s prudent for everyone to take the necessary precautions to stay safe during this tumultuous winter weather.
Be aware of weather updates, abide by local safety recommendations, and prepare for potentially challenging travel conditions as this forecasted winter storm approaches.”
