The Olympics were already in the throes of a tropical system when Nepartak made landfall in week one. Now another, Tropical Storm Mirinae, is expected to impact the final weekend. Events such as rowing were postponed for two days due to the storm.
The center of the storm is expected to pass just southeast of Tokyo on Sunday morning.
For now, it looks like the majority of the rain will be from Saturday night through the first half of Sunday. A few scattered showers and thunderstorms could linger in the evening for the closing ceremony. The winds will be a bit gusty, especially the first half of Sunday, but that shouldn’t be too bad as Mirinae is expected to remain a medium-range tropical storm.
The closing ceremony takes place Sunday at 8 p.m. local time (7 a.m. ET).
Heat, humidity and tropical systems have been the archenemy of athletes during these Olympic Games, and the closing weekend will bring even more of it.
Although heat and humidity in July was common, these levels were above average. Tropical systems can also occur in July, but traditionally the peak months in Japan are August and September.
Why it’s a dangerous combination: It is not only the temperatures but also the humidity. When both are high, conditions can be overwhelming for athletes.
When your body gets too hot, you sweat to cool off. But if the sweat cannot evaporate, the body cannot regulate its temperature. You need evaporation to effectively cool your body.
When relative humidity is high, the body’s evaporation rate decreases, according to the National Weather Service. In other words, the human body feels hotter in humid conditions.
To find cooler temperatures, the Olympic marathon events are taking place this weekend in Sapporo. Sapporo, about 500 miles north of Tokyo, can be up to 40 degrees Fahrenheit colder.
Here are Saturday’s predictions for the women’s marathon:
