Summary
A tropical depression, referred to as a “typhoon egg,” formed near the Sakishima Islands on October 21, moving slowly south of Okinawa. The Japan Meteorological Agency warns of heavy rain and strong winds as an autumn rain front remains stalled south of Japan, extending to the East China Sea. Warm, moist air from a Pacific high-pressure system is fueling rain clouds, with warning-level rainfall expected in the Izu and Nansei Islands by October 23. Strong winds and high waves are anticipated due to intensified pressure gradients, potentially leading to severe sea conditions. Rain and wind simulations for October 22-27 indicate stormy weather in affected areas. Residents are urged to stay updated on weather forecasts and prepare for potential impacts.
