A developing weather system named Shanshan could influence Japan in the coming days, with initial indicators suggesting Primorsky Territory may avoid major disruptions. This assessment comes from Primhydromet and other regional forecasters who are monitoring the situation closely.
Late yesterday, forecasters identified a new tropical storm designated as number 10 and named Shanshan. The system is moving gradually toward the west-northwest, with a central pressure around 1002 hPa and maximum sustained winds near 19–20 m/s. Observers emphasize that the storm’s speed remains modest, which gives meteorologists time to refine forecasts as new data arrive. The broader implication is that the storm’s development could shift, and advisory updates will continue to reflect the latest assessments.
Forecasts project that by week’s end Shanshan could intensify into a typhoon and may make landfall in Japan around August 27. From there, models suggest it would enter the Sea of Japan on August 28, then turn northeast toward Hokkaido as it tracks further along the coast. Based on current trajectories, Primorsky Territory is not expected to experience direct impact, and significant weather changes are unlikely in that region at this time. However, forecasters caution that these projections depend on ongoing data assimilation and could shift with new information.
Officials emphasize that the storm’s path can drift, and updates will follow as monitoring continues.
Earlier in the month, Japan faced widespread flight cancellations tied to Typhoon Ampil. On August 15, Japan Airlines canceled a notable number of flights, totaling 191 services, while All Nippon Airways reported at least 280 cancellations. The disruption affected both domestic travel plans and the schedules of travelers across the country.
Japan Railways, the nation’s rail network operator, did not rule out the possibility of temporarily halting high‑speed Shinkansen services along some eastern and northeastern routes if weather conditions worsen. The potential service changes add another layer of caution for travelers planning trips by rail.
Earlier reports also referenced a broader maritime incident involving a tanker, which raised concerns about potential oil spill threats offshore. Ongoing vigilance from maritime authorities continues to inform shipping decisions and environmental monitoring.
