TS Talas Update #18 (Landfall)

Tropical Storm Talas continues to move across Japan today and is now crossing into the Okayama Prefecture in Western Honshu. It was last located approximately 150km east of Osaka. Maximum sustained winds remain at 95kph gusting to 120kph. Talas is moving northward at 15kph.

Latest Radar Image from JMA continues to show very heavy rain over parts of Chugoku, Kinki, and Shikoku Regions. Rainfall reports so far range from 200 to 400mm with isolated amounts of up to 900mm! Places in Nara Prefecture in the Kii Peninsula got some of the heaviest rains which made the rivers swell, killing at least one person there.

Rainfall will continue to fall in these areas for another 12 hours or so. Additional 200 to 300mm of rain is expected. Weather in Shikoku, however, should slowly begin to improve tonight. Meanwhile, winds of 30 to 50kph will continue to batter Chugoku, Kinki, and Shikoku Regions, especially those along the coast. Wind gusts of as high as 120kph should also be expected.

Tropical Storm Talas will exit land and move into the Sea of Japan early tomorrow (Sunday) and should begin to accelerate towards the northeast. It is expected to move into the Sakhalin Islands of the Russian Far-East by Monday as a weak system--perhaps as an extra tropical cyclone. High waves and occasional rain will still affect western portions of Northern Honshu including Chubu and Tohoku Regions and also Hokkaido.

A new Tropical Depression has formed! TD 16W was last located approximately 900km north northeast of Guam. Maximum sustained winds are at 45kph gusting to 75kph. TD 16W is moving east northeastward at 15kph. Early forecasts from agencies and computer models show this system avoiding any landmass. It is forecast to start turning north tonight in response to a Subtropical Ridge to the northeast. TD 16W could intensify into a tropical storm tomorrow and will continue strengthening for at least another 2 days as the environment remains favorable.

We will have another update tomorrow morning and hopefully, we will also be able to put up a Video Update so please stay tuned.
