A low-pressure area has formed over the Southwest Bay of Bengal near the North Tamil Nadu and South Andhra Pradesh coasts, bringing heavy rains to Chennai and surrounding areas from November 12 to 15, 2024.

This system, along with a coastal trough, has strengthened the northeast winds, causing moderate to heavy rain, particularly in Chennai’s Nungambakkam and Minambakkam areas, which received 36mm and 57mm of rainfall, respectively, over the past 24 hours.

The system is moving slowly westward and will continue to affect the area for the next few days.

Rains are expected to be moderate and intermittent, with some heavy spells likely to disrupt transport and connectivity. The rain intensity will be higher in the evenings and nights through November 15, with broader clearing expected by November 17, 2024.
