Japan is braced for torrential rain and 120mph winds as Super Typhoon Vongfong sweeps north towards the country's southern islands.
The storm, which will be Japan's second typhoon in a week, was moving extremely slowly on Friday afternoon - raising the risk of landslides and flooding when it makes landfall this weekend.
Satellite images taken of Vongfong, which means 'wasp' in Cantonese, suggest that the eye of the hurricane is approximately 50 miles wide.

Striking: Nasa astronaut Reid Wiseman, who is currently serving as a flight engineer aboard the International Space Station, tweeted this striking picture of Vongfong - swirling across the ocean
Approach: Waves smashing the shores of the island of Okinawa, southern Japan, show waves up to 50ft high
Threatening: Infrared satellite images suggest that the eye of the hurricane is approximately 50 miles wide
Vongfong is currently following the path of Phanfone, a typhoon that slammed the mainland on Monday, disrupting transport and prompting evacuation advisories for hundreds of thousands of people
Earlier in the day, Nasa astronaut Reid Wiseman, who is currently serving as a flight engineer aboard the International Space Station, tweeted a picture of Vongfong, and said: 'I’ve seen many from here, but none like this.'
His striking shot shows thick white clouds swirling across the ocean.
At one point the typhoon rivalled last year's devastating typhoon Haiyan, one of the strongest tropical cyclones ever recorded, which killed more than 6,000 people in the Philippines alone when it struck in December last year.
