Why in the news

Cloudbursts across Himalayan states exposed weak climate readiness and early warning.

Key facts

  • Threshold: above 100 mm per hour over roughly 30 sq. km.
  • Typical in Himalayan regions where monsoon winds, cold winds and terrain interact.
  • Effects spread: landslides, flash floods, downstream damage.
  • Global warming and shifting monsoon raise frequency and intensity.

Challenges

  • Drainage: urban flooding in Delhi, Mumbai and Bengaluru shows poor planning.
  • Data gaps: small affected areas lack rain gauges; IMD lacks dense networks for hyper-local forecasts.
  • Preparedness: fragile slopes face unregulated building and tourism.

Way forward

  • Strengthen IMD with dense instruments and computing power.
  • Map vulnerable zones with satellite imagery and past data.
  • Coordinate IMD, scientists, planners and authorities.
  • Upgrade drainage, regulate construction, reach communities with warnings.

Exam angle

  • Definition threshold of a cloudburst.
  • Forecasting agency: IMD.

Test yourself

1. A cloudburst is defined as rainfall exceeding what rate over roughly 30 sq. km?

The notes define it as above 100 mm per hour over about 30 sq. km.

2. Which agency is said to lack dense weather-monitoring networks for hyper-local forecasts?

IMD lacks the dense networks needed for hyper-local forecasting.

3. Where were over 60 lives lost in less than a week in the 2025 cloudburst events?

The loss of over 60 lives was reported in J&K.
