India Monsoon Alert: IMD Forecasts Heavy Rainfall and Thunderstorms

The southwest monsoon is intensifying across India, delivering extreme precipitation to northeastern states while advancing toward northern and central regions. The India Meteorological Department (IMD) has issued critical warnings for torrential downpours, severe thunderstorms, and localized flooding, alongside lingering heatwave conditions in isolated pockets.

The southwest monsoon is advancing across several states, bringing rain, thunderstorms and strong winds. Heavy rainfall is likely in Northeast India, while Delhi, Haryana and southern states may receive showers.

Weather activity is projected to intensify significantly throughout the country on Monday. Documentation from the IMD indicates that the monsoon system is progressing rapidly toward Maharashtra, Telangana, Odisha, Jharkhand, Bihar, and eastern Uttar Pradesh.

Consequently, persistent precipitation will dominate Northeast India, eastern territories, and the peninsular coastline. Multiple regions face a combination of severe thunderstorms, frequent cloud-to-ground lightning, and high-velocity winds alongside heavy downpours.

Heavy Rain Alert for Northeast and Eastern India

The northeastern states of Assam, Meghalaya, Arunachal Pradesh, Nagaland, Manipur, Mizoram, and Tripura are braced for moderate to heavy precipitation on June 22, 2026. Selected locales within these zones are at risk of experiencing extremely heavy rainfall accumulations.

Concurrently, intense precipitation models are tracking over Bihar, Jharkhand, West Bengal, Odisha, and Sikkim. These eastern states are under active thunderstorm and lightning advisories, prompting meteorologists to urge agricultural workers and commuters to monitor local updates.

Delhi, Haryana and North India May See Showers

Atmospheric dynamics across northwestern and central India will remain highly variable. Light to moderate rainfall alongside convective thunderstorm developments is anticipated across Delhi, Haryana, Punjab, Himachal Pradesh, Uttarakhand, Rajasthan, and western Uttar Pradesh.

Conversely, territories in eastern Uttar Pradesh and Vidarbha are subjected to lingering hot and humid conditions. Meteorological models do not rule out isolated heatwave occurrences, while Madhya Pradesh and Chhattisgarh maintain overcast skies with scattered precipitation.

Monsoon Rain to Continue Across Southern States

The peninsular monsoon current will sustain widespread showers across Kerala, Karnataka, Tamil Nadu, Telangana, and Andhra Pradesh.

Severe downpours are forecast for Goa, coastal Karnataka, and Kerala. Concurrently, precipitation volumes will expand across Vidarbha, Marathwada, and central Maharashtra, where strong winds and lightning will drive down ambient temperatures.

Delhi Weather Forecast for Monday

The national capital registered a maximum temperature of 38.9 degrees Celsius on Sunday, representing a marginal 0.3 degrees elevation above the historical seasonal baseline.

The local weather bureau expects thunderstorms and rain to develop on Monday. Ambient temperatures are projected to fluctuate between a maximum of 38 degrees Celsius and a minimum of 27 degrees Celsius.

In the financial capital, the IMD sustained a yellow alert for Mumbai and adjacent districts valid through June 24, 2026. The metropolitan region faces moderate precipitation, lightning hazards, and sudden wind gusts peaking at 40 kmph.

Thunderstorms and Rain Expected in Haryana

A sharp atmospheric shift altered weather parameters in Haryana late Sunday following a day of intense thermal heating. Heavy downpours hit Sirsa, Bhiwani, and Rewari, while Fatehabad, Hisar, and Panipat experienced dense cloud cover and turbulent winds.

Data from the Meteorological Centre in Chandigarh indicated nocturnal light rain tracking toward Ambala and Kaithal.

For June 22, 2026, the IMD predicts light to moderate precipitation paired with convective storms in Sirsa, Fatehabad, Hisar, Jind, Kaithal, and Kurukshetra. Residual showers will hit Sirsa, Fatehabad, Hisar, and Bhiwani on June 23, 2026, before dry air stabilizes Haryana on June 24, 2026.

Future Outlook

The southwest monsoon 2026 is positioned for further geographic expansion. Favorable atmospheric dynamics are establishing conditions that will allow the primary monsoon front to penetrate deeper into Maharashtra, Telangana, Odisha, Jharkhand, Bihar, and Chhattisgarh by June 23, 2026. While this progression ensures agricultural relief and a drop in seasonal temperatures across northern India, it introduces significant hydrological risks. Low-lying urban sectors face acute waterlogging challenges, whereas the mountainous tracts of Sub-Himalayan West Bengal, Sikkim, and the northeastern states remain highly vulnerable to terrain failure and catastrophic landslides through June 25, 2026.

FAQs

Which regions in India are under an extreme rainfall warning?

Northeast India, specifically Meghalaya, Assam, and Arunachal Pradesh, alongside Sub-Himalayan West Bengal, Sikkim, and Coastal Karnataka, face heavy to extremely heavy rainfall warnings extending through June 25, 2026.

What weather alerts have been issued for Mumbai and Delhi?

Mumbai is under a yellow alert until June 24, 2026, warning of thunderstorms, lightning, and gusty winds up to 40 kmph. Delhi is forecast to receive shifting cloud cover, thunderstorms, and cooling showers on Monday.

Why does Northeast India experience such high rainfall volumes during the monsoon?

The region sits at the base of the Eastern Himalayas. The Bay of Bengal branch of the southwest monsoon funnels vast volumes of tropical moisture northward, which then impacts the mountain walls, causing rapid condensation and extreme orographic precipitation.

Are heatwave conditions completely over in India?

No, isolated heatwave conditions and high humidity persist in portions of East Uttar Pradesh, East Madhya Pradesh, Vidarbha, Chhattisgarh, and Telangana, though oncoming monsoon rains are expected to provide relief shortly.
