Typhoon Shanshan is an active tropical cyclone that poses a typhoon threat to Japan in August 2024. The tenth named storm and fourth typhoon of the annual typhoon season. Shanshan was first noted near the Mariana Islands on August 20, with deep convection beginning to consolidate. The following day, the Japan Meteorological Agency (JMA) upgraded it to a tropical storm and named it Shanshan. Early the next day, both the JMA and the Joint Typhoon Warning Center (JTWC) classified it as a typhoon.

Unknown
Extratropical cyclone, remnant low, tropical disturbance, or monsoon depressionThe origins of Typhoon Shanshan can be traced back to August 20, when the Japan Meteorological Agency (JMA) reported that a low-pressure area had formed near the Mariana Islands.[1] At midnight on August 21, both the JMA and the United States Joint Typhoon Warning Center (JTWC) upgraded the tropical depression, with the latter designating the system as 11W due to deep convection beginning to consolidate into a central dense overcast.[2][3] Shortly after, the depression intensified into a tropical storm and was named Shanshan by the JMA due to low vertical wind shear, warm sea surface temperatures, and high ocean heat content.[4] However, Shanshan's movement was nearly stationary due to the weak steering flow.[4] Around 12:00 UTC on August 22, the JMA upgraded it to a severe tropical storm, citing Dvorak technique—a method of determining a tropical cyclone's intensity based on satellite appearance—which indicated an estimate of 95 km/h (60 mph).[5] A ragged eye-like feature appeared on satellite imagery on August 23, and early the next day, both the JMA and the JTWC upgraded it to a typhoon.[6][7] Shanshan began developing poleward outflow into the west-northwest edge of a tropical upper tropospheric trough cell and then turned northward due to the interaction with an upper vortex.[8][9]
Preparations and impact

Authorities are urging residents near the typhoon's projected path to brace for severe winds and heavy rainfall, as well as the possibility of lightning strikes, landslides and flooding. Even areas on the storm's eastern flank, farther from its center, could face adverse weather as Shanshan approaches.[10]
