The India Meteorological Department (IMD) has issued a national weather bulletin for Sunday, August 2, 2026, keeping multiple states under heightened administrative vigil as active monsoon systems generate heavy to extremely heavy precipitation. The IMD weather forecast August 2 2026 highlights a persistent low-pressure area over Southeast Rajasthan and adjoining North Gujarat, coupled with an active offshore trough running along the Arabian Sea coastline, driving intense rainfall across Western, Southern, and Northern India.
High-alert warnings remain active across several maritime and inland states. Severe Red Alerts and high-intensity Orange Alerts have been designated across key districts in Gujarat, Kerala, Coastal Karnataka, and the Northeastern states. Meanwhile, the monsoon trough is shifting northward, intensifying rainfall activity across the Indo-Gangetic plains, Himachal Pradesh, Uttarakhand, and Delhi-NCR.
This report delivers a thorough, fact-verified breakdown of synoptic atmospheric drivers, emergency deep-dives into Red Alert districts, regional city-by-city weather profiles, hydrological and marine advisories, and public safety directives for August 2, 2026.
Section 1
Synoptic Atmospheric Drivers (August 2, 2026)
Primary Low-Pressure System: Well-marked low-pressure area over Southeast Rajasthan & North Gujarat weakening into a low-pressure corridor while pulling massive Arabian Sea moisture.
Active Offshore Trough: Extends along the mean sea level from the South Gujarat coastline down to the North Kerala maritime boundary.
East-West Shear Zone: Positioned roughly along 20°N latitude across Central and North Peninsular India, enhancing convective cloud bands.
Northward Trough Shift: Monsoon trough pulling moisture into the Indo-Gangetic plains, Himachal Pradesh, Uttarakhand, and Delhi-NCR.
A. The Rajasthan–Gujarat Low-Pressure Feedback Loop
The dominant driver for August 2 is the well-marked low-pressure area positioned over Southeast Rajasthan and adjoining North Gujarat. As this system moves slowly, it acts as an atmospheric vacuum, drawing deep tropical moisture from the East-Central Arabian Sea. This moisture flux collides with regional landmasses, triggering organized mesoscale convective systems (MCS) capable of producing short-duration rainfall rates exceeding 30 mm to 50 mm per hour.
B. The West Coast Offshore Trough and Shear Zone
Running parallel to the western littoral, an active offshore trough extends continuously from the South Gujarat coast down to the North Kerala coast. Fueled by strong southwesterly winds blowing at 40 to 50 kmph with gusts up to 60 kmph, this marine trough pushes moisture-laden air directly against the windward slopes of the Western Ghats. Concurrently, an east-west shear zone positioned along 20°N latitude consolidates rainbands over Konkan, Goa, Madhya Maharashtra, and Coastal Karnataka.
C. The Northward Shift of the Monsoon Trough
Further north, the monsoon trough is transitioning toward its near-normal position across the Indo-Gangetic plains. The interaction between easterly winds from the Bay of Bengal and low-level southwesterly winds from the Arabian Sea is expanding rainfall coverage across Punjab, Haryana, Delhi-NCR, Uttar Pradesh, Himachal Pradesh, and Uttarakhand.

Onshore winds off the Gulf of Khambhat will drive continuous rainbands inland, impacting Surat (Limbayat, Udhna, Varachha). Ukai Dam discharge is being monitored.
Section 3
Emergency Focus: Kerala & Mahe Rain Emergency & Coastal Warnings
Kerala continues to face significant weather impacts on August 2, 2026. Following extremely heavy rainfall on August 1 that resulted in tragic drownings in Malappuram and Kottayam, the IMD has transitioned early Red Warnings into a Widespread Orange Alert for 12 districts, while maintaining heavy rainfall and high wave alerts.
Kerala District Warning Map & Marine High Wave Alert Overview
High Range & Southern Belt (Idukki, Pathanamthitta, Kottayam)
Saturated hill slopes along the Western Ghats carry heightened risks of landslides and mudslides. Water levels in the Pamba, Manimala, and Meenachil rivers remain high. Night travel across Munnar-Gappu and Peerade corridors has been restricted.
Central Kerala (Ernakulam, Thrissur, Palakkad)
In Kochi urban agglomeration, high tides combined with continuous rain passes pose waterlogging risks in MG Road, West Kochi, and Kalamassery. Periyar and Chalakudy catchments are on flood watch.
Malabar Belt (Kozhikode, Wayanad, Kannur, Kasaragod)
Runoff from the Wayanad hills keeps streams feeding the Chaliyar and Kabini rivers swollen. INCOIS has issued a High Wave Alert (2.9m to 3.1m swells) for Kannur and Kasaragod coastlines.
