Weather alerts have been raised along the coastal areas of South India as Cyclone Ditvaah, deepening in the Bay of Bengal, is moving towards India. The India Meteorological Department (IMD) has issued a red/orange alert for coastal districts of Tamil Nadu, Puducherry, and Andhra Pradesh.

Ditvaah's path: From where to where?

Cyclone Ditvaah originated in the southwestern part of the Bay of Bengal, forming near the coast of Sri Lanka.

According to the latest forecast from the IMD, the storm is expected to move in a north-northwest (NNW) direction and reach the coasts of northern Tamil Nadu, Puducherry, and southern Andhra Pradesh by the morning of November 30.

Currently, the wind speed of the storm is 65–75 km/h, with gusts reaching 90–100 km/h.

Waves of up to 4–5 meters are expected in coastal areas—making conditions dangerous for coastal areas and fishermen.

Rainfall, storm surge, and possible disruption—Who is affected?

Tamil Nadu.

The IMD has issued red and orange alerts for several districts in Tamil Nadu.

Delta regions, particularly Thanjavur, Tiruvarur, Nagapattinam, Mayiladuthurai, and Pudukkottai, could receive 20 cm or more of rainfall in 24 hours.

Major cities like Chennai, Kanchipuram, Chengalpattu, and Tiruvallur are also likely to experience heavy rain and strong winds, leading to urban flooding, road logging, and traffic disruptions.

Andhra Pradesh / Rayalaseema.

Dikatvaha will also impact the southern coastal areas of Andhra Pradesh and Rayalaseema. Heavy to very heavy rain is expected here from November 28th to December 2nd.

Heavy rain and waterlogging are likely, especially in districts like Chittoor, Tirupati, Nellore, Prakasam, and Kadapa.

Hazards, Damage, and Potential Impacts-





Strong winds can topple trees, billboards, and power lines, potentially causing power outages, falling trees, and endangering life and property.

Risk for fishermen at sea — Fishermen have been advised against venturing into the sea due to high waves and rough seas.

Coastal buildings—old houses, huts, and farmland—could all be affected. Flooding, waterlogging, and storm-force winds could impact agriculture, crops, and local populations.

Waterlogging in cities, traffic disruptions, power and water outages, and school and college closures—disruptions such as these will be common.

What to do to stay secure

Coastal residents—move to temporary shelters if directed by the administration.

Do not venture into the sea, stay away from fishing and boats—as sea conditions are dangerous.

Keep electricity, water, rations, and medicines handy.

Strengthen windows and doors, and secure loose objects like roofs, brooms, and other items—there's a risk of them falling due to high winds.

Keep electrical appliances off, especially in the event of heavy rain or lightning.

Follow the instructions given by the state government, local administration, NDRF, and SDRF.

Is this just a storm, or a sign of a bigger change?

Cyclone Ditvaah—if not addressed immediately, could prove to be far more dangerous than a normal weather event. Because:

Densely populated areas of the coastal states of South India, vulnerable slums, agricultural crops, and the livelihoods of fishermen—all could be directly affected.

Due to climate change and rising sea temperatures, the intensity and frequency of such cyclones are increasing.

Therefore, better preparedness is needed in areas such as drinking water, relief, flood control, strengthening coastal structures, and disaster management.
