Tropical Storm Tembin Update #20

Tropical Storm Tembin is now heading across the East China Sea and could make landfall in South Korea tomorrow. It was last located approximately 280km southeast of Shanghai or about 430km southwest of Jeju Island. Maximum sustained winds remain at 110kph with gusts of up to 140kph. Tembin is currently moving northward at 20kph.

IR Image from NRLMRY

Latest satellite image shows the core of Tembin remains intact despite the increasing upper-level winds. The system is starting to get sheared, however, with rainbands spreading outward ahead of the system. Tembin has also managed to avoid impacting Shanghai although some rainshowers have been reported as the outer bands of Tembin moved briefly along the coastal sections of Zhejiang Province. Tembin should maintain its structure upon landfall despite the worsening atmospheric conditions.

Radar from KMA

Latest radar image from South Korea is starting to pick up rains associated with Tembin. Rain showers could start later tonight, especially along Jeju Island. It will get heavier throughout tomorrow (Thursday) as Tembin is forecast to make landfall in South Korea. Rains of up to 200mm possible in some areas and could even last into Friday morning.

Forecast Track (NOT OFFICIAL!)

Forecast track is taking Tembin towards the southwestern portion of South Korea tomorrow between 10am and 3pm. It will pass south of Seoul during the afternoon hours and should weaken to a Tropical Depression by tomorrow evening. It could become an extra-tropical cyclone as early as Friday as it moves into the Sea of Japan. Unfortunately, it looks like South Korea will be impacted, once again, with strong winds and heavy rains. Please continue monitoring this system via the Korean Meteorological Administration (link above) for the latest radar images, warnings, and forecasts.

We'll have another update tomorrow. Stay safe!
