A fresh Western Disturbance has approached the Western Himalayas. With this, we can expect light to moderate rain and thunderstorm activity over Jammu and Kashmir, Himachal Pradesh and Uttarakhand. We can also witness isolated snowfall over the higher reaches of these states.
Significant obstruction is not likely in the tunnel rescue operations in Uttarakhand due to these weather activities. Weather activities will be much milder over Uttarakhand than in other parts of the Western Himalayas.
We have not seen any significant Western Disturbance in October or November. An active Western Disturbance was seen around November 9 and 10, which induced a Circulation over the plains, resulting in good rain over both the plains and the hills of North India. That system had washed away the pollutants over Delhi and NCR.
However, such a system is not expected over the Western Himalayas anytime soon. Moreover, a feeble system may be seen by the end of the month but it will not affect the plains as such.
