During the Monsoon season, there are periods when the Monsoon trough shifts to the foothills of Himalayas, which leads to sharp decrease in rainfall over most parts of the country but increase along the Himalayas and parts of Northeast India and Southern Peninsula.
Monsoon in India then takes a break with mid of August being moreprone to ‘breaks’ and that too longer breaks. Consequently, Northeast and parts of South India continue to receive good showers while rest of the country is mainly dry.
Weather in North India
The axis of Monsoon trough continues to run closer to the foothills of the Himalayas. Northwest India is facing a grim situation in terms of Monsoon rain. The region is observing an unprecedented spell of dry weather for almost ten days. More alarming is the fact that Punjab, Haryana and Delhi are observing 100% rainfall deficit on a daily basis.
Delhi has been experiencing record breaking temperatures since the last couple of days. The Palam Observatory recorded 39.6°C as the maximum on Saturday, which is the second highest temperature observed in Delhi in the last ten years. The highest in the month of August in a decade has been 40.1°C, recorded on 11th August, 2009.
On Friday as well, the temperature had settle at 39.6°C. The city has not observed a drop of rain in almost two weeks, making it the longest spell of dry weather in August.
Even the hilly regions of Himachal Pradesh and Uttarakhand are facing similar weather conditions. However, the upper air cyclonic circulation over north Pakistan and adjoining Jammu & Kashmir could bring some light rain, if at all, over the states of Jammu & Kashmir and Himachal Pradesh.
Weather in East and Northeast India
The prevailing break monsoon condition is favourable for some good rain in East and Northeast India, particularly along the foothills. Sikkim and Sub Himalayan West Bengal and Northeast will receive scattered rain during next 24 hours. West Bengal, Jharkhand, Odisha and extreme northeast Bihar could receive light rain as well.
Central India will remain almost dry, except for Gujarat, Marathwada and Madhya Maharashtra. As reiterated by Skymet Meteorology Division in India, the well-marked low pressure area over eastcentral Arabian sea and adjoining areas of Maharashtra is expected to bring a sigh of relief for the people of Gujarat, observing dry weather for almost a week now.
Weather in South India
Mainly light rain will continue over entire peninsular India, particularly Andhra Pradesh, Karnataka, parts of Tamil Nadu and north Kerala.
