The Southwest Monsoon, which blankets the Indian subcontinent with its cooling rains during the summer months, is gradually bidding farewell to the region. Recent meteorological updates indicate that conditions are becoming increasingly favorable for the withdrawal of the Southwest Monsoon from various parts of India. In this article, we’ll delve into the latest developments and weather features influencing this seasonal transition.
Withdrawal Progress
As of the latest IMD reports, the Southwest Monsoon is on the retreat from several regions across the country. The areas expected to witness further withdrawal during the next two days include:
- East Uttar Pradesh
- East Madhya Pradesh
- Some parts of Bihar
- Jharkhand
- Gangetic West Bengal
- Odisha
- Chhattisgarh
- Telangana
- Some more parts of Maharashtra
- Central Arabian Sea
This gradual withdrawal process is a significant milestone in the transition from the rainy season to the post-monsoon period, marking the onset of autumn and winter across India.
Weather Features Influencing Withdrawal
Several weather features are currently influencing the withdrawal of the Southwest Monsoon. Here are the key factors at play:
- North-South Trough: A north-south trough is running from Sikkim to the coastal areas of West Bengal in the lower tropospheric levels. This trough is contributing to the changing weather patterns in these regions.
- East-West Trough: Another trough extends from the central parts of Chhattisgarh to south Tamil Nadu, cutting across Telangana and interior Karnataka in the lower tropospheric levels. This feature is also playing a role in the monsoon’s retreat.
Regional Outlook
Here’s a regional breakdown of the weather expectations:
Northeast India: Expect light to moderate rainfall at many places, with isolated heavy rainfall accompanied by thunderstorms and lightning likely over Arunachal Pradesh and Assam & Meghalaya on October 9th, with a gradual reduction thereafter.
East India: In Sub-Himalayan West Bengal & Sikkim, light to moderate rainfall is expected over the next five days, accompanied by thunderstorms and lightning.
South India: Some areas in Tamil Nadu are likely to experience light to moderate rainfall from October 9th to 11th, with isolated heavy rainfall and thunderstorms. South Interior Karnataka and Kerala are also expected to receive similar weather conditions during these dates.
Northwest India: Light rainfall is anticipated in some places, with isolated thunderstorms and lightning in Himachal Pradesh and Uttarakhand on October 9th.
As the Southwest Monsoon continues its withdrawal from these regions, the weather dynamics across India will gradually shift towards the post-monsoon phase, bringing changes in temperature, humidity, and precipitation patterns. It is essential for residents and farmers in these regions to stay updated with local weather forecasts and advisories to plan their activities accordingly during this transition period.
