Western disturbances usually affect the Western Himalayas and adjoining northern plains of the country between November and February. The intensity and frequency of Western disturbances start decreasing in March. By the month of April, Western disturbances start travelling in upper latitudes. This usual pattern sometimes gets altered.
This year we have seen a lesser number of Western disturbances in the month of February and were also feeble in nature. The intensity of Western disturbances once again picked up pace in the month of March. A good amount of rain, thundershowers as well as snowfall have occurred over the Western Himalayas. Northern plain states of the country such as Punjab, Haryana, Delhi, West and Central Uttar Pradesh, North Madhya Pradesh, North and East Rajasthan have recorded scattered rain in March.
The present Western disturbance will give rain and snow from Jammu & Kashmir to Uttarakhand. Another Western disturbance is expected around March 16. Between March 21 and 23 another intense Western disturbance is expected to approach Jammu and Kashmir. Western Himalayas will continue to get rain and light snowfall until the end of March this year. The impact of these Western disturbances will be felt across North West India also. After the passage of each Western disturbance, winds from north-west leads to a drop in temperatures, as they will be blowing from snow-clad mountains. We can expect the maximum of Northwest plains to remain in check. And chances of the intense heatwave will get reduced.
Northwest India may receive scattered rain and thundershowers between March 17th and 18th, and Central India between March 18th and 22nd.
