The storm center was last located approximately 150km east of Shanghai, China or about 770km southwest of Seoul, South Korea. Maximum sustained winds are down to 150kph with gusts of up to 185kph. Typhoon Chan-Hom is currently moving north northeastward at 20kph.

Latest satellite image shows the center of Chan-Hom moving close to the populous city of Shanghai. The system has weakened further this evening with convective activity decreasing and dry air starting to wrap around the circulation. However, good outflow is slowing down the weakening. Either way, the biggest threat for the areas affected is the widespread flooding due to the rain bands of Chan-Hom.

Radar from CMA

Latest radar from Eastern China shows bands of light to moderate rains are moving north now towards the provinces of Shandong and Jiangsu. Many areas in Zhejiang received well over 200mm of rain with news reports showing widespread flooding in the region. Even though not shown in the image above, parts of the Korean Peninsula are also starting to receive rains brought by Chan-Hom. The region expected to receive its own share of heavy rains in the next 24 to 48 hours.

Typhoon Chan-Hom will continue to move quickly across the Yellow Sea this evening with the potential landfall in North Korea either late this evening (Sunday) or early Monday morning. The entire peninsula is forecast to receive anywhere from 50 to as much as 250mm of rainfall in the next two days. Chan-Hom will rapidly weaken after landfall and dissipate as it exits into the Sea of Japan.
