Severe winter weather conditions are set to impact Yamaguchi Prefecture as the Shimonoseki Local Meteorological Observatory has issued multiple warnings concerning stormy winds, heavy snow, and lightning on March 18, 2025. At 10:46 AM, the observatory provided important weather information for the prefecture, and by 11:06 AM, stormy weather warnings were firmly put in place for Shimonoseki and the northern parts of the region.
The upcoming forecast indicates the arrival of a low-pressure system characterized by strong cold air, which is triggering significant changes to the weather across the prefecture. The conditions are expected to deteriorate as winds from the west become more pronounced, with rain increasingly mixing with snow as the day progresses. Particularly from the evening of March 18 through the morning of March 19, heavy snowfall is predicted, primarily affecting mountainous areas.
Forecasts predict maximum wind speeds reaching up to 20 meters, with potential instantaneous gusts of 30 meters along the Sea of Japan side. The Seto Inland Sea is also anticipated to experience strong winds, albeit slightly lower, with expected speeds of 18 meters and maximum gusts reaching 30 meters. This increase in wind and snow makes travel dangerous, prompting the observatory to recommend careful driving and heightened awareness of transportation disruptions.
The Shimonoseki Local Meteorological Observatory emphasized the severity of the impending storm. A statement read, "Heavy snow is expected to increase, especially in mountainous areas near the borders with Shimane and Hiroshima prefectures." They also issued warnings about the stormy weather affecting the coast along the Sea of Japan. The typical winter conditions are expected to be exacerbated by unstable atmospheric conditions, leading to potential thunderstorms and other severe weather phenomena.
According to the updated meteorological report released at 4:34 PM on the same day, areas across Yamaguchi Prefecture are at risk from heavy snowfall expected overnight and through to midday on March 19. The observatory has outlined snowfall totals of up to 40 centimeters expected for the mountainous regions and approximately 5 centimeters for plains. The highest accumulations may occur where conditions remain persistent.
Further, warnings were issued for thunder and rapid, gusty winds. These unpredictable conditions lead to apprehension about transportation safety. Roads, especially those leading through mountainous passes, may become particularly treacherous due to increased snow covering, potentially leading to halted traffic and hazards on the road. Meteorologists have advised against unnecessary travel during this time, particularly for those using standard tires.
Residents were urged to stay vigilant as dangerously windy conditions may lead to adverse visibility and intense winds capable of making driving hazardous. The observatory's warnings include recommendations for staying indoors and avoiding any unnecessary journeys. Local authorities remind the public to be prepared for unexpected weather changes and demands placed on community infrastructure due to snow accumulation and related emergencies.
With daytime temperatures only expected to peak at around 9 to 10 degrees Celsius on March 19, the wintry blast is unlikely to ease anytime soon. The extreme cold and heavy snowfall pose concerns for events such as school graduations scheduled for March 19, urging event organizers and visitors to take precautionary measures. Authorities are asking residents to exercise caution when venturing out and to remain attentive to official announcements and updates about changing weather conditions throughout this storm period.
The next weather update is scheduled for around 6:00 AM on March 19, 2025, where residents can expect clearer insights about the storm's progression and potential easing of conditions. Additional precautions will be outlined as the meteorology team continues to monitor the weather closely and provides updates as necessary.
The report from the Shimonoseki Local Meteorological Observatory is clear: individuals should remain alert and prepared for the significant winter weather impacting Yamaguchi Prefecture over the next 24 hours. Drivers are reminded to adhere to safety practices, plan for delays, and stay informed through local news outlets for the most accurate and up-to-date information available. Staying safe and well-informed is the priority as the region faces the forces of nature.
