Weather officials in Japan say a large and powerful typhoon is expected to approach Okinawa Prefecture and the Amami region of Kagoshima Prefecture through Saturday, and to near the Kyushu region on Sunday.
Typhoon Nanmadol may affect many regions, especially during the upcoming three-day weekend through Monday. It is expected to travel through eastern and northern Japan through Tuesday. The Meteorological Agency is urging people across the country to brace for it.
The Meteorological Agency said Nanmadol was traveling northwest over the sea south of Japan at 15 kilometers per hour as of 3 p.m. on Friday.
The typhoon had a central atmospheric pressure of 950 hectopascals. It was packing winds of up to 162 kilometers per hour near its center, with peak gusts reaching 216 kilometers per hour.
The Amami region and southern Kyushu are forecast to have maximum winds of 108 kilometers per hour through Saturday, while winds of up to 90 kilometers per hour are expected in Okinawa.
Winds are likely to get even stronger on Sunday.
Seas will also be very rough around southern Kyushu, Okinawa and Amami, with waves expected to reach heights of 12 meters in southern Kyushu and 10 meters in Okinawa and Amami on Saturday.
Tide levels are expected to rise in northern Kyushu, the Chugoku region and the Shikoku region from around Sunday. Storm surges and high waves could cause flooding in coastal areas.
Rainfall in the 24-hour period through late Saturday afternoon could reach 200 millimeters in southern Kyushu and the Tokai region, 180 millimeters in Okinawa and 150 millimeters in Amami, Shikoku, and the Kinki region.
The storm may bring heavy rain primarily to western Japan as it approaches. Southern Kyushu may get record rainfall exceeding the average for the entire month of September.
Weather officials are urging caution against wind gusts, high waves and storm surges, as well as landslides, flooding and swollen rivers, mainly in western Japan, Okinawa and Amami.
The typhoon could disrupt transportation services during the three-day holiday.
Weather officials called on residents of regions where the typhoon is approaching to stay updated with the latest information, refrain from non-essential outings, and make preparations well ahead of time.
A Meteorological Agency forecaster warned that the large typhoon is expected to approach Kyushu on Sunday while maintaining its strength.
He described Nanmadol as a dangerous typhoon, saying it is expected to bring violent winds to Kyushu and Okinawa, and to dump heavy rains mainly on southern Kyushu and on the Pacific side of the Shikoku region.
He also said that as the typhoon is large, rain and winds could intensify even in areas far from it, and that its effects could be prolonged.
He said that the typhoon is likely to approach Kyushu with a very strong force before cutting across the Japanese archipelago. He called on people across the country to be on the alert.
