During the month of June, Northwest India received good Monsoon showers and the month ended with a surplus of 31 percent. However, during this period, East Uttar Pradesh, Haryana, Delhi, and Himachal Pradesh were the meteorological divisions that were slightly rain deficient.
By the end of July, the rainfall figures for Northwest India dropped down to 11 percent. By the end of August, the figures further decreased to an extent where the region observed a deficiency of 8 percent. August was the least Monsoon active month for Northwest India, and very little rain was observed over the region.
No weather systems affected the above-mentioned states of North and Northwest India. The Western Disturbances affecting these regions were also not strong enough and failed to give significant rainfall over the region.
Most of September has gone being almost dry. However, occasional light rainfall has been observed over parts of Rajasthan, Punjab, and the hilly states of North India. However, from September 11, winds have changed their course and have started blowing from the easterly direction. This change has increased the humidity levels resulting in sultry conditions.
Fortunately, relief is in sight in terms of rain and improvement in the humid conditions as a well-marked low has weakened into a low pressure area and will continue to move in a northerly direction. The system will affect Rajasthan, Delhi, Haryana, West Uttar Pradesh, and Punjab.
During the next two to three days, fairly widespread rain is expected over most parts of Northwest India. This rainfall episode may be the last spell of Monsoon rains. The upcoming spell will give relief to the residents, but it may not be able to improve the rainfall deficiency.
By September 23, dry weather conditions will be observed as the easterly winds will be replaced by the westerlies leading to a significant decrease in the moisture levels.
