As the monsoon season officially begins its withdrawal from Northwest India, a significant weather dichotomy grips the nation on Saturday, September 20, 2025. While northern cities like Delhi and Jaipur welcome sunshine and rising temperatures, the eastern states are under the threat of intense rainfall, prompting alerts from the India Meteorological Department (IMD).
What Does the Monsoon Withdrawal Mean?
The monsoon’s retreat is a phased process indicating the end of seasonal rains for specific regions. Starting from the northwest, it gradually pulls back southwards over several weeks. This explains the clear skies and drop in humidity in places like Punjab, Haryana, and parts of Rajasthan. However, its withdrawal does not mean the end of rain everywhere. In fact, it often intensifies rainfall in eastern and northeastern parts of the country for a period.
Which Regions Are Under Threat Today?
In a number of eastern and northeastern states, the IMD has issued warnings for heavy to extremely heavy rains. The alert highlights a significant risk for:
- Andaman & Nicobar Islands
- Arunachal Pradesh
- Assam
- Meghalaya
- Bihar
- Sub-Himalayan West Bengal & Sikkim
An orange alert signals that authorities must be ready, as heavy rains could cause waterlogging, traffic issues, and rising river levels.
