Cyclone Ditwah is steadily advancing toward the Tamil Nadu and Puducherry coast, prompting the India Meteorological Department (IMD) to issue red alerts for several districts. The cyclone, which originated as a deep depression off the Sri Lankan coast, is expected to intensify into a cyclonic storm as it moves north-northwest across the Bay of Bengal, making landfall around November 30. Due to its slow progression and large wind field, heavy to extremely heavy rainfall is anticipated over the coastal and adjoining districts of Tamil Nadu and Puducherry, along with strong winds ranging from 35 to 50 kmph.

The IMD has flagged four districts in Tamil Nadu’s Cauvery Delta region—Thanjavur, Tiruvarur, Nagapattinam, and Mayiladuthurai—with red alerts signifying the threat of extremely heavy rain exceeding 20 cm in 24 hours. Additional districts, including Cuddalore, Villupuram, Chengalpattu, as well as Puducherry and Karaikal, are also under heightened weather warnings. The coastal cities, including Chennai, are expected to experience heavy to very heavy rainfall, exacerbated by the cyclone’s moisture convergence, which raises risks of localized flooding. Authorities have advised fishermen to avoid venturing into the sea and residents to take necessary precautions against the impending weather.

This cyclone scenario resembles past events where slow-moving systems along the Tamil Nadu coast caused prolonged rainfall and waterlogging, often disrupting daily life and transport. For example, the delayed onset of the monsoon or previous cyclones like Ogni in 2006 brought similar conditions marked by heavy rains and strong winds. The IMD and local government agencies continue to monitor Ditwah’s trajectory closely, updating alerts as its progress influences landfall timing and intensity. Preparations include shutting down schools in vulnerable areas and mobilizing emergency services to minimize damage.

Residents in the affected regions should stay updated with official advisories, especially in districts under red alerts, and heed safety instructions regarding travel and outdoor activities. Given Ditwah’s current forecast track, the coastal and delta zones need to brace for a multi-day spell of adverse weather, with the possibility of thunderstorms and squally winds continuing until December 1.

Cyclone Ditwah is poised to bring significant weather disruption to Tamil Nadu and Puducherry, with red alerts signaling dangerous rainfall and wind conditions expected in several coastal districts. Proactive precautions and adherence to weather updates are key for mitigating its impact in the coming days.
