Shanghai meteorological observatory says the main impact window is Aug 8–11. From late Aug 7 through Aug 10 land gusts will increase, reaching force 8–9, with stronger gusts in the Yangtze estuary, river/coastal areas and Yangshan port.

Shanghai meteorological observatory says the main impact window is Aug 8–11. From late Aug 7 through Aug 10 land gusts will increase, reaching force 8–9, with stronger gusts in the Yangtze estuary, river/coastal areas and Yangshan port. Heavy rain is expected Aug 8–10, with cumulative totals potentially exceeding 100 mm. Forecast uncertainty is high after the system enters the East China Sea due to interactions with mid‑latitude cold air, the subtropical high and other systems; an extreme scenario of landfall in northern Zhejiang overnight Aug 9–10 followed by northwestward movement would produce the most severe wind and rain for Shanghai.
