Very warm and humid conditions will challenge racers at the 104th edition of the Tour de France on Sunday.
Soaring temperatures will continue to reach dangerous levels through Stage 9 on Sunday.
Though racers will climb into cooler air at higher elevations during the stage, heat and humidity will continue to challenge racers during the climbs and at lower elevations.

The average high during the beginning of July for the region is near 23 C (74 F). High temperatures at lower elevations on Sunday will be near 28 C (83 F), while across the mountains, temperatures will be held to more comfortable levels.
Although the mountains will bring some cooler air, the surrounding heat and humidity will help to fuel showers and thunderstorms.
Thunderstorms could be numerous on Sunday afternoon along the race course. Gusty wind, hail, heavy downpours and frequent lightning will all threaten racers and spectators along the course.
