Since last week of August, the axis of Monsoon trough shifted to the foothills of the Himalayas leading to dry westerly winds over northern plains. Also, Monsoon has started to withdraw from parts of Punjab and Haryana from September 8. In addition to this, no active Western Disturbance (WD) or induced cyclonic circulation has affected Delhi or nearby areas. All these factors have contributed towards a long dry spell over Delhi-NCR region.
Since the beginning of September, dry westerly winds kept weather conditions in the national capital region largely comfortable. Even though day temperature remained on the higher side, the absence of sultry conditions ensured that weather in Delhi remained rather enjoyable.
Now, a low pressure area has developed over the Bay of Bengal, and the trough from this system is extending up to western parts of Uttar Pradesh. Due to this, moist and humid south-easterly winds have been hitting Delhi. As a result, a noticeable increase has been witnessed in humidity levels, and these conditions are likely to last for another week.
As per Skymet Meteorology Division in India, weather over Delhi-NCR will continue to remain dry and sultry during next few days. There are chances of patchy rain and thundershowers in the region, but the intensity of rain will not be very high. Thus, Delhi’s chances of crossing last year’s 82.66 mm rain figure for September look bleak. In fact, September 2015 may go down as the driest September for Delhi in a decade.
