Key Points
- New low-pressure likely near Myanmar–Bangladesh coast around Sep 25; heavy rain in Odisha Sep 23–26, Chhattisgarh & coastal Andhra Sep 24–26.
- Delhi-NCR to stay hot and humid with clear skies till Sep 23; max/min about 1–2°C above normal.
- Landslides, road blockages in Himachal–Uttarakhand amid persistent heavy rain; mobility remains disrupted.
- Monsoon withdrawal underway from northwest; stray showers to persist in Rajasthan even during retreat.
- Northeast India: rain spell to continue for 4–5 days; local flooding risk in vulnerable pockets.
New Delhi: The monsoon is entering its final phase with withdrawal advancing over parts of northwest India, yet fresh rain spells are likely in the east and central belt due to a brewing Bay of Bengal system late this week. A developing low-pressure area near the Myanmar–Bangladesh coast around September 25 could push significant moisture into Odisha, Chhattisgarh, and coastal Andhra, renewing widespread showers after a brief lull.
Himalayan states: landslides and disruption
Continuous heavy rain and cloudbursts in Himachal Pradesh and Uttarakhand have aggravated landslide risks and road closures, impacting inter-district travel, essential supplies, and tourism movement. Mountain districts should expect periodic traffic halts, debris clearance operations, and short-notice advisories as saturated slopes remain unstable.
Rajasthan: rain in retreat phase
Even as monsoon withdrawal progresses, parts of Rajasthan have recorded heavy showers with a focused alert across several districts. Light drizzle may continue in pockets during the withdrawal window, while isolated heavy rain remains possible where circulations or the monsoon trough briefly realign.
Bay of Bengal low-pressure: who gets rain
A fresh low-pressure system is likely to form around September 25 near the Myanmar–Bangladesh coast. Under its influence:
- Odisha: heavy rain likely September 23–26.
- Chhattisgarh and coastal Andhra Pradesh: heavy rain likely September 24–26.
This system may also sustain showers across Northeast India over the next 4–5 days, with localized flooding and waterlogging in low-lying areas.
Delhi-NCR: heat and humidity persists
No significant temperature change has been observed in the past 24 hours, and clear to mainly clear skies are expected through September 23. Maximums are likely around 34–36°C with minimums 23–25°C, roughly 1–2°C above normal, keeping humid heat conditions in place, especially during late afternoons.
Uttar Pradesh: clearer, hotter stretch
Light rain has occurred in select districts including Lucknow, but a dry stretch is expected statewide until September 25. Western UP, under clearer skies, is likely to feel hotter than the east, with daytime discomfort due to higher insolation and residual humidity.
Bihar: heavy rain concerns
Heavy rainfall is forecast for parts of Bihar, adding to showers already recorded up to September 20. Rural belts face potential crop damage particularly in paddy fields while urban centers should prepare for waterlogging, traffic snarls, and drain stress through the next few days.
Uttarakhand: delayed monsoon exit likely
Despite the seasonal norm of late-September withdrawal, ongoing rain activity has pushed back a clear departure signal in Uttarakhand. With above-normal seasonal totals so far and intermittent systems still active, meteorologists are refraining from announcing a firm withdrawal date for the state.
When will the monsoon withdraw completely?
Monsoon withdrawal commenced around September 4 from extreme northwest and typically completes by mid-October. While climatology places broad retreat between mid-September and mid-October, renewed Bay of Bengal activity around September 25 could slow the pace over central and eastern India. Early winter-like conditions may begin to be felt by late October in parts of north and northwest India as the synoptic pattern shifts.
