A deep depression over the southwest Bay of Bengal has intensified into Cyclonic Storm Ditwah, prompting the India Meteorological Department (IMD) to issue alerts for coastal regions of north Tamil Nadu, Puducherry, and southern Andhra Pradesh. The storm is expected to make landfall by early Sunday, November 30, raising concerns over heavy rainfall, strong winds, and rough seas.
Storm Genesis and Projected Path
Initially identified as a deep depression, the weather system strengthened into a cyclonic storm by Thursday morning. It is located over the southwest Bay of Bengal, near the southeastern coast of Sri Lanka. Forecast models indicate that the storm will move north-northwestwards across the Bay, heading toward the coasts of north Tamil Nadu, Puducherry, and adjoining south Andhra Pradesh. Coastal impact is expected late Saturday, with landfall anticipated by early Sunday.
Expected Impact
Meteorologists have warned of heavy to very heavy rainfall along the coastal belt from November 28 to 30. Districts such as Ramanathapuram, Pudukkottai, Thanjavur, Tiruvarur, and Nagapattinam are likely to witness intense rainfall.
Wind speeds are forecast in the range of 80–90 km/h, with gusts possibly reaching 100 km/h, creating rough sea conditions. Authorities have urged fishermen to remain ashore and advised coastal residents to take necessary precautions.
Key warnings:
- Prolonged heavy rainfall expected along the Tamil Nadu, Puducherry, and south Andhra Pradesh coast.
- Strong winds capable of causing damage to structures and uprooting trees.
- Rough seas posing risk to maritime activity.
Alerts and Preparedness
The IMD has issued yellow and orange alerts across multiple districts, urging local authorities and residents to prepare for potential flooding and storm-related hazards. Coastal administrations are expected to raise storm-warning signals at major ports, with mariners advised to suspend sea travel until the situation stabilizes.
Residents of low-lying and flood-prone areas, particularly delta regions, are advised to remain alert and follow official updates for possible evacuations. Emergency response teams are on standby to mitigate damage and assist affected populations.
Significance of Rapid Intensification
Cyclone Ditwah’s swift transformation from a deep depression into a cyclonic storm highlights the volatile nature of weather systems in the Bay of Bengal during this season. Such rapid intensification increases the potential for sudden heavy rainfall, wind damage, and coastal flooding, emphasizing the need for immediate preparedness.
Authorities continue to monitor the storm closely and have urged the public to adhere strictly to safety advisories as Cyclone Ditwah approaches the eastern coast of India.
