IMD Southwest Monsoon Arrives Late in Delhi, IOD May Offset El Niño Deficit in 2026

Hurricane Polo Turns Category 5; Strong El Niño May Cause 451,000 Additional Global Heat Deaths

Hurricane Polo has intensified into a Category 5 storm off Mexico's Pacific coast, with maximum sustained winds of 270 kmph. This is unfolding against an unusually strong El Niño that the WMO expects to persist through February 2027. El Niño is being watched closely because it can disrupt rainfall worldwide—the Climate Impact Lab projects 451,000 additional heat-related deaths globally, including about 15,800 in India.

Monsoon Revival: Rainfall Deficiency Drops to 11.5%, Kharif Sowing Gap Narrows to 2.9%

The monsoon has revived significantly, reducing cumulative rainfall deficiency from 22.8% to 11.5% and narrowing the kharif sowing gap from 20.8% to 2.9%. However, El Niño is strengthening into a 'very strong' event, posing a serious threat to the upcoming rabi season. Proactive supply-side management will be crucial for food security.

NOAA Projects 69% Chance of Historic El Niño Since 1950; IMD Reports Below-Normal Monsoon

A potentially historic El Niño is developing in the Pacific, with NOAA projecting a 69% chance it will exceed the strongest events since 1950. For India, the impact may lag by 40-45 days, likely after the southwest monsoon's official withdrawal, though the current monsoon is already 12% below normal.

WMO Warns 'Very Strong' El Nino Till Feb 2027; Threat to Monsoon & Winters

The World Meteorological Organization (WMO) warns of a 'very strong' El Nino that will persist until February 2027, with potential to disrupt global weather patterns, including India's monsoon and winter. This is a critical update for exam aspirants as it links to geography, climate, and agriculture.

Maharashtra Drought Declared in 75% Tehsils, Monsoon Deficit 11.9% Raises Rabi Crop Concerns

Maharashtra has declared drought in nearly three-fourths of its tehsils, with the southwest monsoon ending 11.9% below average. The article warns of a poor rabi harvest due to depleted water reserves and a strong El Niño, urging duty-free imports of all pulses to manage food supply.

2026 Monsoon Prediction Failure: El Niño Accuracy vs. Sub-seasonal Erratic Evolution Challenges

Climate models accurately predicted the 2026 El Niño and a deficient monsoon season, but failed to capture the erratic, sub-seasonal swings—like June’s 40% deficit followed by July’s recovery—which severely impacted farmers. This highlights a critical gap: while seasonal all-India rainfall totals can be forecast, long-lead predictions of spatial and temporal monsoon evolution remain unreliable, and AI-driven hybrid models are the most promising way forward.

Bihar Floods: Ganga Breaches Previous HFLs Despite 27% Rain Deficit; Farakka Barrage & Backwater Effect Key Causes

Bihar experienced severe flooding in September 2026 despite a 27% rainfall deficit, because the Ganga rose first (not the Nepal-origin rivers) due to upstream rainfall in UP, creating a 'backwater effect' that blocked tributary drainage. The article also highlights the role of siltation from the Farakka Barrage and the approaching expiry of the 1996 India-Bangladesh Farakka Treaty.

72% of Punjab's Groundwater Blocks in 'Red Zone' as Extraction Rate Hits 152% - Pani Bachao Scheme Offers Cash for Conservation

Punjab's groundwater crisis deepens with an extraction rate of 152%, and 72% of its 153 blocks classified as 'over-exploited'. The rice-wheat cropping system, supported by subsidised electricity and assured procurement, drives this overuse. The 'Pani Bachao, Paisa Kamao' scheme offers cash incentives for electricity conservation, but low enrolment limits impact. This is a critical issue for UPSC Environment, Agriculture, and Governance papers.
