Typhoon Trami is bringing strong winds to Okinawa Prefecture and the Amami Islands in Kagoshima Prefecture, southern Japan. Weather officials say the storm could affect other parts of the country through Monday.
The Meteorological Agency says the very strong storm was 40 kilometers south-southeast of Kume Island in Okinawa Prefecture at 12 PM on Saturday. Trami is moving north at a speed of 20 kilometers per hour.
It has a central atmospheric pressure of 950 hectopascals and is carrying winds of up to 162 kilometers per hour near its center.
Maximum instantaneous wind speed topped 180 kilometers per hour on Saturday morning in some parts of Okinawa.
Weather officials forecast up to 400 millimeters of rain for Amami, and up to 250 millimeters of rain for Okinawa in the 24 hours through Sunday noon.
Trami is predicted to head northeast as it gains speed. It will come very close to western parts of Japan's main islands on Sunday and to eastern and northern Japan later.
Weather officials have called on people across Japan to stay alert through Monday for heavy rain, strong winds and rough seas.
