Heavy rainfall from a Bay of Bengal system may disrupt Chennai's operations. The India Meteorological Department is tracking a brewing depression over the Bay of Bengal, which is forecast to bring isolated heavy rain to Tamil Nadu on Tuesday and Wednesday.

Why it matters
As a major economic hub, Chennai relies heavily on stable infrastructure and uninterrupted supply chains. Severe weather events, such as those forecast from the Bay of Bengal, pose a direct threat to commercial activity, potentially causing delays and operational shutdowns across the city.
This weather system is part of a wider pattern of unsettled weather across the South Peninsula, affecting multiple states including Andhra Pradesh, Kerala, and Telangana. The proximity of this system to other recently battered areas, like those affected by Cyclone Arnab, suggests a high regional vulnerability to successive weather disturbances.
