Temperature averaged 2°C to 7°C (4°F-14°F) persisted over an area extending from eastern Siberia southward into north-central China. The mercury reached 35°C (95°F) as far north as Yakutsk, Russia.
Thunderstorms brought moderate to heavy rains of 50 to 230 mm (2.00”-9.20”) to parts of the region extending from China's Sichuan and Guizhou Provinces northeastward to southern and central Japan. Some of the heavy rains in eastern China were fueled by the remnants of Typhoon Toraji.
