IMD forecasts swift monsoon advance into North India this week with heavy rains and thunderstorms, offering relief after heatwaves, though farmers must prepare for waterlogging and wind damage.

The India Meteorological Department (IMD) has announced that conditions are highly favourable for the southwest monsoon to advance rapidly across large parts of north and central India over the coming days. As of late June 2026, the monsoon is poised to cover additional areas including parts of Uttar Pradesh, Uttarakhand, Himachal Pradesh, Jammu & Kashmir, Ladakh, southeast Rajasthan, and remaining sections of Gujarat and Madhya Pradesh.

This progression comes after a somewhat delayed and uneven start to the 2026 monsoon season, which began with revisions in onset predictions and concerns over below-normal rainfall. Earlier long-range forecasts had pegged the seasonal rainfall at around 90-92 per cent of the long-period average (LPA), raising worries about deficient rains in several regions. However, recent activity signals a strengthening phase, bringing much-needed precipitation to parched farmlands.

Rainfall Alerts: Heavy to Extremely Heavy Spells Forecast

IMD warnings highlight widespread heavy to very heavy rainfall across multiple zones in the next week. Northeast India and Sub-Himalayan West Bengal and Sikkim are expected to receive extensive rain over the next five days, with extremely heavy falls possible at isolated spots on June 29. Konkan and Goa and Madhya Maharashtra may also see very heavy to extremely heavy rainfall up to July 3.

Other states in the line of the monsoon’s fire include Uttarakhand, Himachal Pradesh, Punjab, Haryana, Uttar Pradesh, Bihar, Odisha, Jharkhand, Chhattisgarh, Madhya Pradesh, Vidarbha, Gujarat, and parts of southern states like Kerala, Karnataka, Telangana, and Tamil Nadu. Thunderstorms accompanied by lightning and gusty winds (40-60 kmph) are likely in many areas, with thundersqualls reaching 50-70 kmph in East Rajasthan on June 29 and July 1-2. Dust storms could affect West Rajasthan between July 2 and 5.

This burst of activity aligns with broader monsoon dynamics, including the influence of western disturbances that have already triggered thunderstorms and rains in northwest and central India. Recent observations show the monsoon advancing steadily into Maharashtra, Telangana, Odisha, Jharkhand, Bihar, and parts of Chhattisgarh in mid-to-late June, setting the stage for its northward push.

Lingering Heatwave Before Cooling Relief

Despite the incoming rains, isolated heatwave conditions are expected to persist briefly. East Uttar Pradesh may face heatwave on June 29, while Haryana, Chandigarh, and Delhi could experience it on June 29-30. However, maximum temperatures are forecast to drop significantly: by 4-5°C across northwest India by July 4, and by 3-4°C in Maharashtra by July 3. Gujarat and Madhya Pradesh will also see gradual cooling.

In Delhi-NCR, the transition will be noticeable. Very light to moderate rainfall with thunderstorms is predicted on June 30, July 1, and July 2, bringing maximum temperatures down from 39-41°C to 34-36°C, providing respite from the scorching heat that has gripped the region.

This pattern reflects a common monsoon transition phase where pre-monsoon heat gives way to convective activity. Earlier in June, severe heatwave conditions were noted in parts of Uttar Pradesh alongside advancing rains elsewhere, underscoring the uneven nature of the season.

Implications for Agriculture and Rural Economy

The monsoon advance is critical for India’s agrarian heartlands, particularly as Kharif sowing gains momentum. Timely rains can boost paddy, maize, pulses, and other crops, but the intensity of expected downpours poses risks of waterlogging, flooding in low-lying areas, and damage to standing crops or infrastructure.

IMD has issued specific agrometeorological advisories for farmers. Key recommendations include ensuring proper drainage in fields to avoid waterlogging, postponing sowing or transplanting in heavy rainfall zones, harvesting mature produce before storms, and providing physical support to vulnerable crops like banana and sugarcane against strong winds. Livestock keepers should shelter animals during heavy rain, protect feed from moisture, and ensure ample water during residual heat periods.

Experts note that while the overall 2026 monsoon outlook remains cautious due to potential climate influences in an El Niño year, this week’s surge could help narrow rainfall deficits observed in some pockets earlier in the season. Northeast India, for instance, has been receiving good rainfall, but consistency across the country remains a watchpoint.

Broader Weather Patterns and Preparedness

Thunderstorm activity with lightning has been prominent recently across northwest, central, east, and northeast India. Gusty winds and hail in some instances add to the hazards. Authorities in vulnerable states are urged to monitor low-lying areas, rivers, and urban drainage systems.

The combination of monsoon currents and western disturbances is fuelling this active spell. Public advisories emphasise avoiding open areas during thunderstorms, securing loose objects, and heeding orange alerts for intense lightning in central and eastern regions.

As the monsoon deepens its foothold, urban centres like Delhi are expected to transition from dry, hot conditions to more humid, rainy weather, which could bring its own challenges such as traffic disruptions or localized flooding but will ultimately alleviate heat stress on populations.

Long-Term Seasonal Context

The 2026 southwest monsoon season started with IMD revising its predictions downward, citing a higher probability of below-normal rainfall. Factors such as transitioning climate patterns have been at play. Despite this, active phases like the current one demonstrate the monsoon’s variability and capacity to deliver concentrated bursts.

States in the Himalayan foothills and northern plains must remain vigilant against landslides or flash floods triggered by heavy orographic rainfall. Southern and western coasts, already seeing robust activity, continue to contribute to national rainfall totals.

Farmers and policymakers alike will be closely tracking daily updates as the monsoon establishes itself more firmly. Successful progression could support robust Kharif output, vital for food security and rural livelihoods, while excessive rains in short spells necessitate proactive disaster management.

This week’s forecast marks a pivotal shift: from lingering summer heat to the dynamic, life-giving yet potentially disruptive forces of the monsoon. IMD has urged residents and stakeholders across North India to prepare for a mix of relief and caution as rains advance.
