Typhoon Ma-on, currently some 700 miles south of Tokyo, is beginning to head towards Japan. The storm will peak at 120 knots by this time tomorrow. Ma-on will then veer northeast and slowly pass just to the south of Japan. There is considerable uncertainty over its proximity to land, and any weakening which will result from passage over land. The storm will be well above 65 knots (the lower threshold for typhoon strength), and is expected to be between 90 and 110 knots as it passes near or to the south of Honshu, Japan.
