# IMD issues red alert for four North Bengal districts as heavy rain looms over Kolkata

India’s weather office has issued a red alert for four districts in North Bengal, warning of extremely heavy rainfall as the region is battered by persistent downpours. The India Meteorological Department (IMD) flagged Darjeeling, Jalpaiguri, Kalimpong and Alipurduar for the highest-level warning, while signalling that Kolkata could also see bouts of heavy rain over the coming week.

North Bengal

Red alerts are IMD’s most severe rainfall warnings, typically issued when weather conditions are expected to be highly disruptive and potentially dangerous. For North Bengal, the alert covers hill and foothill districts where intense rain can quickly translate into landslides, flooding, road closures, and disruptions to rail and road links that connect the region to the rest of West Bengal and neighbouring states.

The warning also extends the week’s broader monsoon pattern in eastern India, where rainfall can fluctuate sharply across short distances. In West Bengal, heavy rain in the northern districts often coincides with spillover impacts farther south, including intermittent heavy showers in Kolkata that strain drainage, slow commuter traffic, and disrupt airport and rail operations.

A red alert in North Bengal is not just a local weather event; it can ripple through logistics corridors that move food, fuel, and consumer goods between India’s Northeast and the rest of the country. When hill roads are cut or rail routes are slowed by waterlogging, supply chains can snarl, increasing transit times for perishable goods and raising costs for transporters and distributors.

The alert also highlights how monsoon volatility can create uneven risk across a single state, forcing local administrations to balance disaster response resources between landslide-prone hill areas and flood-prone urban zones like Kolkata. If heavy rain persists through the week, disruptions could spread to schools, offices, and healthcare access in vulnerable pockets, while municipal systems face pressure to keep key arteries and drainage channels functioning.

Watch for IMD’s next district-level bulletin and whether the red alert is

extended or expanded beyond Darjeeling, Jalpaiguri, Kalimpong and Alipurduar by 2026-07-23.

If the red alert is maintained or widened, that would signal sustained

extreme rainfall risk and a higher probability of prolonged transport and local service disruptions; if it is downgraded to an orange or yellow alert, it would indicate easing intensity even if showers continue across Kolkata and surrounding areas.
