A tropical storm that has caught the attention of Olympic organizers could make landfall near Tokyo on Tuesday, forecasts showed Sunday, with the Meteorological Agency warning of heavy rain, strong winds and high waves.

While not expected to strengthen into a typhoon, Tropical Storm Nepartak could impact a wide area, with the forecast showing a possible Tuesday landfall in the Kanto area, including Tokyo, or the Tohoku region, further north.

Some Olympic rowing events set for early this week have already been rescheduled ahead of the storm's arrival.
