The fire has ravaged more than 1,600 hectares (6.18 square miles) some 60 km (37 miles) from the finish line in Les Angles and is still spreading.
Images of the fire show billowing black smoke, with eyewitnesses reporting scorching winds, hot ground, difficulty breathing in the vicinity and poor visibility beyond 2 meters (6.56 feet).
The race route will remain unchanged, but the Tour's publicity caravan will not drive along the last 40 km into France from Spain where it began on Saturday.

Cyclists will proceed autonomously and only with staff strictly necessary to keep the race going, according to the prefecture of the Pyrenees-Orientales department.
