India Weather Forecast & IMD National Bulletin: July 30, 2026 City-by-City Outlook and Assam Flood Emergency Report

The India Meteorological Department (IMD) has issued a comprehensive national weather bulletin for Thursday, July 30, 2026, warning of widespread monsoon activity, heavy-to-very-heavy rainfall spells across the Western Ghats, East-Central India, and the Himalayan foothills, alongside isolated extremely heavy downpours in Northeast India.

With the active Southwest Monsoon trough maintaining a favorable alignment across the Gangetic plains down to the Bay of Bengal, maritime moisture feeding into the sub-Himalayan belt continues to trigger severe localized weather.

Meanwhile, emergency teams remain on high alert as the Assam flood current situation continues to demand national focus, with major river systems including the Brahmaputra overflowing their banks and affecting hundreds of thousands of residents across multiple districts.

1. Special Disaster Focus: Current Flood and Monsoon Situation in Assam

Northeast India, particularly the state of Assam, remains under severe hydrometeorological distress as persistent, heavy monsoonal downpours across the upper catchments of Arunachal Pradesh and Bhutan continue to feed river networks across the Brahmaputra and Barak valleys.

A. Hydrological Inundation and River Mechanics

According to updates from the Central Water Commission (CWC) and the Assam State Disaster Management Authority (ASDMA), the Brahmaputra River continues to flow above the critical danger mark at Nematighat in Jorhat district and at Dhubri. Major tributaries including the Kopili at Kampur, the Disang at Nanglamoraghat, and the Subansiri River are exhibiting high discharge velocity, exacerbating embankment breaches.

The district of Dhubri remains the worst-hit sector, with over 180,000 residents affected by overflowing river waters, followed by Nagaon, Cachar, Lakhimpur, and Morigaon. In total, over 1,100 villages across 19 districts remain inundated, destroying thousands of hectares of standing Sali paddy crops.

B. Relief Operations, Kaziranga, and Infrastructure

Teams from the National Disaster Response Force (NDRF), State Disaster Response Force (SDRF), and local administration personnel are executing round-the-clock boat evacuations. Over 120 relief camps and distribution centers have been operationalized, housing more than 45,000 displaced citizens.

In the world-famous Kaziranga National Park and Tiger Reserve (KNPTR), floodwaters have submerged nearly 40% of the forest camp infrastructure. Forest guards and animal rescue teams are patrolling national highways passing through the park corridor (NH-715) to enforce strict speed restrictions, safeguarding migrating Indian one-horned rhinoceroses, wild elephants, and deer seeking higher ground in the neighboring Karbi Anglong hills.

2. Northern India Weather Forecast: Detailed City-by-City Bulletins

Northern India will experience moderate to heavy monsoonal showers on July 30, driven by the interaction between low-level easterly winds and a weak passing Western Disturbance over the Western Himalayan Region.

3. Western India Weather Forecast: Konkan, Goa & Gujarat Bulletins

Western India remains under the influence of an active offshore trough running along the Arabian Sea coastline, producing heavy, continuous rain over the Konkan belt.

Mumbai (Maharashtra): Max 28.5°C | Min 24.0°C | Orange / Red Alert (Heavy to Very Heavy Rain, Isolated Extremely Heavy). The financial capital will witness intense monsoonal activity on July 30. High tide of 4.2m expected at 13:45 could cause waterlogging in Hindmata, Sion, Kurla, and Andheri Subway.

4. Southern India Weather Forecast: Peninsular City Bulletins

Peninsular India will see a split weather regime: active, heavy rainfall along the windward Malabar and Kanara coasts, contrasted with lighter, drier conditions across the interior rain-shadow regions of Tamil Nadu and Andhra Pradesh.

5. Eastern & Central India Weather Forecast: Bay of Bengal System Impact

Driven by an active cyclonic circulation hovering over North Odisha and adjoining Gangetic West Bengal, Eastern and Central India will experience high precipitation levels on July 30.

6. Northeast India Weather Forecast: Widespread Rainfall Across States

The Northeastern states remain the national hot-spot for heavy monsoon precipitation due to strong moisture transport from the Bay of Bengal impinging upon the regional hill topography.
