Powerful Typhoon Mindulle is travelling north over the Pacific Ocean far south of Japan's main island of Honshu. Weather officials warn of strong winds, high waves and heavy rain in parts of the country over the coming days.
Japan's Meteorological Agency says the typhoon was located near the country's southernmost island of Okinotorishima as of 3 p.m. on Monday, slowly moving north-northwest.
It has an atmospheric pressure of 925 hectopascals and is packing maximum winds of 180 kilometers per hour near its center, with gusts reaching around 250 kilometers per hour.
The agency says Mindulle is expected to become stronger over the next two days.
Waves of 6 to 8 meters are expected near Okinawa's Daito Islands from late Tuesday night through Thursday and around the Tokyo-administered Ogasawara Islands from Wednesday through Friday.
Weather officials forecast that the storm will gradually change direction and move to the northeast, approaching Tokyo's Izu Islands around Friday. The officials warn of strong winds, high waves and heavy rain in the area.
They also say the storm may bring strong winds and heavy rain to the Pacific side of eastern and northern Japan.
