The United States’ National Oceanic and Atmospheric Administration (NOAA) confirmed this month that an El Niño has formed in the equatorial Pacific, and placed the odds at about 63% that it will strengthen into a “very strong” — colloquially, a “super” — event by the northern winter. India’s June rainfall, until 16th June, is roughly 35% below normal. The combination has revived a question that returns with every El Niño year: how reliably do the strongest of these events translate into a failed Indian monsoon?

The IMD has highlighted significant weather developments across the country, including the further advance of the southwest monsoon, heavy rainfall activity in several regions, and heat wave conditions in isolated areas. 

(i) Conditions are favourable for further advance of southwest monsoon into some more parts of Maharashtra, Telangana, Odisha, Jharkhand & Bihar, and some parts of Chhattisgarh around June 23, 2026. 

(ii) Isolated heavy to very heavy rainfall likely over sub-Himalayan West Bengal & Sikkim and northeast India during the week with possibility of isolated extremely heavy rainfall over sub-Himalayan West Bengal & Sikkim till June 21. 

(iii) Heat wave conditions very likely in isolated pockets over Konkan & Goa and Madhya Maharashtra today, East Uttar Pradesh & Vidarbha till June 25; Bihar, Telangana till June 21, 2026. 

The India Meteorological Department (IMD) has issued a weather warning, forecasting heavy rainfall activity across parts of the country. Isolated heavy to very heavy rainfall is likely over sub-Himalayan West Bengal, Sikkim and the northeastern States during the week. There is also a possibility of isolated extremely heavy rainfall over sub-Himalayan West Bengal and Sikkim till June 21, 2026. 

The India Meteorological Department (IMD) has issued a weather warning, predicting adverse weather conditions across several parts of the country. Heavy rainfall is expected over Arunachal Pradesh, Nagaland, Manipur, Mizoram, Tripura and parts of Odisha. Heavy showers are also likely in Tamil Nadu and Kerala. Meanwhile, thunderstorm and intense thunderstorm activity are expected over Rajasthan, Gujarat and Chhattisgarh. 

The India Meteorological Department (IMD) has said that conditions are favourable for the further advance of the Southwest monsoon into additional parts of Maharashtra, Telangana, Odisha, Jharkhand and Bihar, as well as some areas of Chhattisgarh, around June 23. 

The India Meteorological Department (IMD) on Saturday (June 20, 2026) said the Southwest monsoon continues to advance steadily across the country, with the northern limit of monsoon currently passing through Harnai, Solapur, Hyderabad, Bhadrachalam, Koraput, Phulbani, Ranchi, Jamui and Muzaffarpur.

Schools in Cyberabad may soon hold online classes once a week during the monsoon season, as police plan to approach educational institutions in an effort to ease school-related traffic congestion and facilitate civic works across the commissionerate.

Cyberabad Police Commissioner M. Ramesh said he will soon hold a meeting with school managements and request them to conduct online classes ideally during mid-week in July and August. If implemented, students would attend eight days of online classes in two months. “This will reduce the pressure on the roads and also allow Cyberabad municipal officials to plan and execute civic works,” he said.
