TOKYO (AP) — A powerful typhoon is advancing toward the Tokyo area, where torrential rains are expected this weekend.

The Japan Meteorological Agency said Typhoon Hagibis was in the Pacific advancing north-northwestward toward Japan's main island. Its winds of 180 kilometers per hour (110 mph) with gusts to 250 kph (156 mph) as of Friday morning were expected to weaken before landfall Saturday.

Up to 800 millimeters (30 inches) of rain was forecast south and west of Tokyo. The capital region may see 600 mm (23.6 inches) of rain.

The storm is expected to disrupt sports and holiday events on the three-day weekend. Two Rugby World Cup matches that were to be played Saturday have already been canceled. And the Defense Ministry cut a three-day annual navy review to just Monday.
