He said a decision on further extending the odd-even rule would be taken later.
"In view of air pollution, the odd-even vehicle system will be applicable for one week from 13th to 20th November...," Gopal Rai said.
He said there is a possibility that the wind speed will increase on November 7, 8 which is expected to reduce the level of pollution.
"As per the forecast, the wind speed will be 12km/hour tomorrow, 7th November and if the speed reaches 10 to 12 km/hour, then there is a possibility that the level of pollution accumulated here might disperse. Similarly, the wind speed will be 8-10 km/hour on 8th November. It is expected that the speed of wind will increase on November 7 and 8 November which will reduce the level of pollution...," he said.
