The approaching fresh western disturbance exists as an induced cyclonic circulation over southwest Rajasthan and started to affect northwest India, scattered rainfall is expecting over Punjab which is likely to lead to very low fire count during next two days. Moreover, stubble transport level wind direction is not so favourable for intrusion. Hence, stubble contribution is estimated to reduce significantly by Friday to around 5 per cent.
