So far, the Tokyo Olympics cycling events have seen road cyclists struggle with the weather conditions of heat and humidity, but with Tropical Storm Nepartak approaching the coast of Japan and the resulting extreme weather conditions, the course changes and possible lightning in the women's cross country mountain bike race has emerged.

According to an official communication from the UCI Technical Delegate, the A line at Joren Rock Garden will be closed early this afternoon Tokyo time, and the entry to the A line at Karesansui Rock Garden will be closed.

The training ramp at Sakura Drop (where Dutchman Mathieu van der Pol crashed early in the men's mountain bike race) will also be restored, although he said on Twitter that he did not know it was being removed.

"Due to the slippery landing surface of the Sakura Drop, the training ramp will be reinstalled to allow riders to roll over the jump, but the A-line will remain open," the UCI technical committee announced.

According to the latest forecast released this morning, temperatures are expected to be in the upper 20s during the competition, which should ease the wet conditions seen earlier in the day.

"Rain will weaken today, but overcast skies will persist. 'There is a chance of thunderstorms during the competition, which may affect the competition.'

The weather has also affected other events, with some, like archery, being rescheduled and the medal-winning event of surfing being moved up. However, the men's mountain bike cross-country race on Monday was spared the rain and extreme weather conditions. Britain's Tom Pidcock won the race, with Matthias Fluechiger (Switzerland) taking silver and David Valero Serrano (Spain) taking bronze.

French elite rider Roana Lecomte, undefeated on the World Cup circuit this year, is the clear favorite to win the women's race. Then there is Sweden's defending Olympic champion Jenny Lisvedos, who has finished in the top five in every World Cup race this year, Pauline Ferrand-Prevot, who has two top-five finishes this season and has won two bronze medals at the World Championships Australia's Rebecca McConnell.
