India Weather Forecast: The Southwest Monsoon is progressing steadily across the Indian subcontinent. Following its official arrival over the Kerala coast, the India Meteorological Department (IMD) has mapped a significant advancement of the weather system into major sectors of the Arabian Sea, Bay of Bengal, and portions of Central and East India.
For commuters, agricultural planners, and residents living in high-alert areas, staying ahead of severe weather shifts is crucial. KRH News breaks down the comprehensive all-India weather forecast and state-wise rain alerts for the week of June 15 to June 21, 2026.
Monsoon Progress Tracker and Northern Limit Status
The Southwest Monsoon has advanced deeper into Karnataka, Telangana, Andhra Pradesh, and the remaining zones of Tamil Nadu. Simultaneously, the eastern branch of the monsoon has established a strong foothold across West Bengal, Sikkim, and parts of Bihar.
According to the latest IMD extended-range updates, conditions remain highly favorable for the monsoon to push further into:
- Remaining sectors of Maharashtra and the Central Arabian Sea.
- Portions of Chhattisgarh, Odisha, and Jharkhand.
- East Uttar Pradesh, accelerating rainfall activity across northern plains later in the week.
Region-Wise Weather Predictions for Next Week in India (June 15 to 21, 2026)
A combination of active monsoon troughs and strong western disturbances will trigger distinct weather patterns across India’s primary geographical zones.
1. Northeast India & Sub-Himalayan West Bengal (Red & Orange Alerts)
The northeastern states face the heaviest precipitation risk this week. Intense southerly and southwesterly winds from the Bay of Bengal are channeling massive moisture over the region.
- Assam, Meghalaya, and Arunachal Pradesh: Widespread heavy to very heavy rainfall (7–20 cm) is expected between June 15 and June 18. Localized flash floods and landslides are likely in hilly terrains.
- Nagaland, Manipur, Mizoram, and Tripura: Regular active thunderstorms accompanied by persistent heavy showers.
2. East and Central India
- West Bengal & Sikkim: Sub-Himalayan West Bengal and Sikkim will see continuous heavy downpours through June 18, shifting down into Gangetic West Bengal by mid-week.
- Bihar & Jharkhand: Fairly widespread rain with high-velocity thundersqualls (speeds reaching up to 50–60 kmph) will impact parts of Bihar and Jharkhand.
- Madhya Pradesh & Chhattisgarh: Isolated to scattered rainfall paired with lightning. Severe squall hazards are likely to decrease slightly over Vidarbha, though spotty heatwave anomalies may linger over localized pockets early in the week.
3. Northwest India & Western Himalayan Region
A fresh Western Disturbance moving across the northern latitudes will keep the regional atmosphere unstable.
- Jammu-Kashmir, Himachal Pradesh, and Uttarakhand: Scattered to fairly widespread light-to-moderate showers will persist. Hikers and travelers should watch for isolated thunderstorms and gusty winds ranging between 40–50 kmph.
- Delhi NCT, Punjab, and Haryana: Transitioning from early pre-monsoon convective cells into standard isolated dust storms and scattered light showers as the week progresses.
4. South Peninsular & West Coast India
- Konkan & Goa: The offshore trough along the west coast ensures regular rainy spells, though heavy downpours will temporarily yield to scattered showers from June 15 onwards.
- Kerala & Coastal Karnataka: Steady monsoon precipitation will continue, providing adequate soil moisture for initial Kharif sowing windows.
