As of 8:00 pm today, the center of TS Man-yi (16W) was located over the sea south of Shikoku-Honshu, Japan...about 245 km southeast of Kochi, Japan or 615 km southwest of Tokyo, Japan...currently moving north-northeast with an increased forward speed of 28 km/hr towards Southern Honshu, Japan.

Maximum Sustained Winds (1-min. avg) have increased to 95 km/hr near the center with higher gusts. Tropical Storm Force Winds (63-100 km/hr) extend outward up to 250 kilometers from the center. Man-yi (16W) remains a very large-sized tropical cyclone with a diameter of 1,110 kilometers across. The 24-hour rainfall accumulation near the center of Man-yi is estimated to be heavy (200 mm).


TS Man-yi (16W) is expected to move northeastward during the next 12 to 24 hours. On the forecast track, the core of Man-Yi will be approaching the southern shores of Shikoku and Honshu later this evening...and will make landfall over Aichi and Shizuoka Prefectures in Honshu, Japan on Monday morning. The system will be along the northeastern coast of Honshu on Monday evening.

TS Man-yi will start to weaken during the next 12 to 24 hours...and will become Extratropical. Advance Intensity Forecast (AIF) shows its 1-minute sustained winds decreasing to just 95 km/hr after crossing Honshu.

The following is the summary of the 1-day forecast outlook on this system:

MONDAY EVENING: Just along the northeastern coast of Honshu...becomes an Extratropical Cyclone...about 145 km east-northeast of Sendai, Japan [8PM SEP 16: 38.7N 142.5E @ 95kph].

*Please be reminded that the Forecast Outlook changes every 6 hours, and the Day 2 and 3 Forecast Tracks have an average error of 100 and 250 km respectively...while the wind speed forecast error, averages 35 kph per day. Therefore, a turn to the left or right of its future track and changes in its wind speed must be anticipated from time to time.
