Extreme weather, including Tokyo's infamous summer heat and an incoming tropical storm, is the latest factor concerning athletes and Olympic organizers at the already problem-plagued summer games.
Temperatures in Tokyo over the weekend hit a high of 93 degrees Fahrenheit and athletes have seen no reprieve from the brutal summer humidity in Japan's capital city.
Heading into this week, the Japan Meteorological Agency forecasts a relatively mild Tuesday (with a high of 84 degrees Fahrenheit) with temperatures again topping 90 degrees for the rest of the week.
Athletes reportedly struggled with the scorching temperatures and extreme heat warning signs were posted at some Olympic venues.
