New Delhi: The monsoon remains vigorous with the India Meteorological Department (IMD) placing several regions under red and orange alerts for heavy to extremely heavy rainfall through the week, driven by a depression crossing coastal Odisha and an active monsoon trough influencing central-western corridors. The IMD’s all-India bulletin highlights extremely heavy rain potential over Konkan & Goa, Gujarat, and ghat areas of Madhya Maharashtra, with spillover effects across Karnataka and coastal belts on staggered days this week.
Delhi-NCR: Yamuna Above Danger Mark; Light Rain, High Humidity
- The Yamuna has breached the danger mark (205.33m) and hovered near the 206m evacuation threshold, prompting relief measures in low-lying pockets such as Yamuna Bazaar; water levels eased slightly by Tuesday evening with the Central Water Commission projecting a fall toward 204.49m by Wednesday evening if upstream discharge remains subdued.
- IMD forecasts generally cloudy skies with very light to light rain or thundershowers today, temperatures around 32–34°C by day and 23–25°C by night; southeast winds 10–20km/h.
