Cyclone ‘Arnab’ LIVE updates | IMD raises wind forecast to 150 kmph gusts; landfall near Yanam; 61 trains cancelled

A tropical cyclone is a large, rotating low-pressure storm that forms over warm tropical seas. It draws energy from warm ocean water and can bring destructive winds, intense rain, high waves and flooding. Landfall means the cyclone’s centre reaches and crosses the coastline. This matters because hazards often intensify for communities near the crossing point.

Cyclone Arnab is expected to cross close to Yanam, between Bapatla and Visakhapatnam, by Wednesday forenoon. The IMD forecast winds of 125 to 135 kmph, with gusts up to 150 kmph. Before landfall, rising waves had already flooded stretches of Uppada, Konapapet and Moolapet in Kakinada district.

The forecast means coastal residents, transport services, farmers and authorities face a short window to prepare. Fishermen were told not to enter the sea on Tuesday and Wednesday. Roads, railways and flights were already being disrupted, while relief teams and control rooms were placed on alert.

Cyclone Arnab is forecast to be a severe coastal threat, with sustained winds of 125 to 135 kmph and gusts up to 150 kmph near landfall. It was moving toward the coast at 20 kmph and lay about 220 kilometres from Visakhapatnam at 8.30 a.m. on October 27. These figures show both its strength and its rapid approach.

The storm’s footprint is wider than the landfall point. Coastal villages near Kakinada were already facing rising waves and flooding. Visakhapatnam received more than 35 millimetres of rain in some locations by noon. The forecast also covered heavy to extremely heavy rain in Chhattisgarh, with strong winds expected in southern Bastar.

The exact reach of the strongest winds and waves can change as the cyclone moves. Still, the reported impacts already span villages, cities, transport links and inland districts. Authorities opened relief preparations across coastal Andhra and kept emergency teams ready in Chhattisgarh.

Winds of 125 to 135 kmph, with gusts up to 150 kmph, can break branches, damage roofs, overturn loose objects and disrupt power or communications. People near the shore also face storm waves and flooding. The danger rises when wind, rain and seawater arrive together. Roads may become impassable, especially on low coastal stretches.

The article gives a direct example at Uppada, Konapapet and Moolapet. Rising waves flooded coastal stretches and pushed toward houses. Roads connecting Uppada with Kakinada and nearby villages were cut off. In Visakhapatnam, some sites recorded about 36 to 37 millimetres of rain within a few hours.

The IMD warned that Arnab could heavily damage farm and horticulture crops and livestock. Local governments were told to prepare relief camps, while disaster teams stood by. Residents should follow official instructions because conditions can worsen quickly as the cyclone approaches landfall.

Transport operators do not need to wait for landfall before acting. A cyclone’s outer rainbands and winds can reach transport corridors early. Flooded roads, fallen trees, poor visibility, high winds and unsafe tracks can threaten passengers and crews. Airports may also face dangerous crosswinds, while airlines must reposition aircraft and manage disrupted schedules.

South Central Railway cancelled 11 trains on Tuesday and Wednesday. The affected services included routes from Hyderabad, Secunderabad and Mahbubnagar to Visakhapatnam, and trains toward Kakinada and Narasapur. At Visakhapatnam airport, four Air India Express flights were cancelled and four IndiGo flights were diverted.

These decisions are precautionary and operational, not proof that the cyclone has already crossed the coast. Passengers were told to check train or flight status before leaving. The IMD also warned that rail, road and air services could be affected, so disruptions may continue as Arnab nears Yanam.

The Godavari delta and nearby coastal districts are exposed because they contain low-lying land near the sea and waterways. Such terrain can be affected by seawater pushed inland by strong winds and waves, as well as by intense rainfall. The article does not provide a detailed map of local elevations, but this is the general reason delta and shoreline communities face heightened flood risk.

At Uppada, Konapapet and Moolapet, rising waves flooded coastal stretches and moved toward houses. Roads connecting Uppada with Kakinada and nearby villages were cut off. Kakinada was about 240 kilometres from Arnab at 8.30 a.m., while Visakhapatnam was about 220 kilometres away.

Visakhapatnam also recorded the State’s heaviest rain by noon, with roughly 37 millimetres at Tulasi Nagar Park and 36 millimetres at the 16th Police Battalion campus. Continued rain, waves and wind could worsen flooding and isolate more communities.

Cyclone response works through linked decisions. The IMD tracks the storm and forecasts its path, winds and rain. Disaster-management authorities turn those forecasts into warnings, evacuation advice, helplines and emergency plans. Local governments manage shelters, roads, health services and rescue operations. Transport agencies then adjust services when routes or operating conditions become unsafe.

For Arnab, the IMD forecast a crossing near Yanam and warned fishermen to stay ashore. APSDMA issued state and district control-room numbers, including emergency numbers 112 and 1070. South Central Railway cancelled 11 trains, while flights at Visakhapatnam were cancelled or diverted. Chhattisgarh kept relief camps open and placed NDRF and SDRF teams on standby.

This coordination helps authorities act before the worst conditions arrive. Health officials in Chhattisgarh were asked to identify pregnant women who might need relocation. Passengers were told to check status directly, and residents could contact district control rooms for assistance.

Tropical cyclones generally form over very warm ocean water when moist air rises and creates a low-pressure area. As more warm, humid air flows inward and rises, the storm gains energy. Earth’s rotation helps the circulation organize around the low-pressure centre. A cyclone can strengthen while warm water and favourable atmospheric conditions continue supplying energy.

The rising air cools and condenses into clouds and rain. Condensation releases heat, which encourages more air to rise and can deepen the storm’s low pressure. Air rushing toward that pressure creates powerful winds. The storm’s rotating circulation also gathers moisture across a broad area, producing intense rain. Strong winds over the sea generate high waves.

Arnab shows this combination clearly. The IMD forecast 125 to 135 kmph winds, gusting to 150 kmph, while Visakhapatnam received more than 35 millimetres in some places by noon. Coastal villages were already facing dangerous waves and flooding before landfall.
