As of 5:00 am today, the center of TS Man-yi (16W) was located over the Western Pacific Ocean...about 370 km west-southwest of Iwo To, Japan or 1,665 km east-northeast of Basco, Batanes...currently moving west-northwest with a forward speed of 24 km/hr towards Southern Japan.

Man-yi (16W) has grown into a very large-sized tropical cyclone with a diameter of 945 kilometers across. The 24-hour rainfall accumulation near the center of Man-yi is estimated to be extreme (400 mm).


TS Man-yi (16W) is expected to move northwest during the next 12 hours...with a gradual turn to the north by 24 hours. By 48 hours, the system will rapidly accelerate as it recurves northeasterly. On the forecast track, the core of Man-Yi will be approaching the southern shores of Honshu on Sunday...and making landfall over Aichi and Shizouka Prefectures in Honshu, Japan by Monday morning.

TS Man-yi will continue to strengthen during the next 48 hours...and could become a Typhoon on Saturday afternoon. Advance Intensity Forecast (AIF) shows its 1-minute sustained winds reaching 130 km/hr prior in making landfall to Southern Honshu.

The following is the summary of the 2-day forecast outlook and an extended 3-day forecast on this system:

SUNDAY MORNING: Continues to intensify as it recurves northward...about 560 km south of Kochi, Japan [5AM SEP 15: 28.6N 134.3E @ 100kph].
MONDAY MORNING: Just along the shores of Southern Honshu...becomes a Typhoon...about 85 km south-southeast of Nagoya, Japan [5AM SEP 16: 34.5N 137.3E @ 130kph].
TUESDAY MORNING: Becomes an Extratropical Cyclone as it accelerates across the Western Pacific Ocean...losing strength...about 515 km east-southeast of Sapporo, Japan [5AM SEP 17: 42.5N 147.7E @ 85kph].

*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.
