Hinnamnor downs trees, power lines on Miyako islands

Powerful typhoon Hinnamnor knocked down some trees in Miyako islands of Okinawa Prefecture in Japan on Sunday. Officials said the slow-moving typhoon could add to rainfall and risks of flooding in the southern region.

The storm will move in intensity over the warm ocean waters of the East China Sea through Monday, as it approaches southern South Korea where it may make a landfall later Monday night.

Into Tuesday Hinnamnor is expected to bring flooding rains that can be life-threatening to South Korea and southwest Japan in addition to destructive winds.
