India 2026 monsoon: Flooding, ~~low-pressure~~ cyclonic systems, and ENSO

The 2026 monsoon season has been characterized by intense volatility, with significant weather disruptions occurring in August, September, and October. In August, heavy monsoon activity and low-pressure systems over the Bay of Bengal triggered widespread flooding across eastern and central India. Odisha faced critical conditions, with over 1.3 million people affected. In northern India, Delhi-NCR faced severe waterlogging and flight cancellations. Throughout September, a series of low-pressure systems drove intense precipitation, causing severe flooding in Bihar and Uttar Pradesh. In mid-September, the India Meteorological Department (IMD) issued red alerts for Gujarat and Delhi-NCR, prompting the deployment of 38 NDRF and SDRF teams. A significant weather system in the Bay of Bengal intensified into a depression, making landfall near Kalingapatnam on the night of September 23. This system brought squally winds up to 75 kmph and heavy rainfall to Odisha and Andhra Pradesh, prompting school closures and red alerts in several districts. The system also influenced rainfall in Nepal and Sri Lanka. In Maharashtra, intense rainfall caused urban flooding and power outages during the Ganesh festival. By late September, Madhya Pradesh faced orange alerts for extremely heavy rainfall as the monsoon approached its conclusion. ~~By late September, a depression in the Bay of Bengal continued to disrupt life in South Bengal and coastal areas, while heavy rains also hit Telangana and Andhra Pradesh.~~ Despite the official withdrawal of the southwest monsoon on September 23, sudden showers affected Delhi, and low-pressure areas triggered significant rainfall in Uttar Pradesh and Madhya Pradesh. By the end of September, the monsoon began withdrawing from the North Indian plains, leading to a dry spell and rising temperatures in Delhi and Punjab. In early October, ~~weather patterns shifted significantly. While North India experienced warm, dry conditions,~~ the ~~northeast~~ southwest monsoon ~~brought renewed instability~~ continued its withdrawal across Delhi-NCR, Punjab, and Chhattisgarh. In Delhi-NCR, the IMD reported complete withdrawal, resulting in clear skies, morning chills, and high daytime temperatures between 35-36 degrees Celsius with humidity up to 85 percent. Air quality in Delhi entered the ~~southern peninsula.~~ ‘moderate’ category.
