Cyclone Arnab closing in on Andhra coast, 4 states on alert ahead of landfall

Cyclone Arnab is a powerful rotating storm over the Bay of Bengal. The India Meteorological Department, or IMD, reported that it was moving westwards toward Andhra Pradesh. A cyclone makes landfall when its centre crosses the coastline from the sea onto land. This matters because damaging winds, intense rain and dangerous coastal conditions can then affect homes, roads, power networks and communities.

Arnab was about 650 kilometres east-southeast of Visakhapatnam at 5:30 am on Monday. The IMD expected it to strengthen into a severe cyclonic storm and then a very severe cyclonic storm. It forecast landfall between Bapatla and Visakhapatnam, close to Yanam, with gusts reaching 140 kmph.

Before landfall, authorities restrict fishing, prepare rescue teams and warn residents. Andhra Pradesh planned control rooms and alerts for coastal villages. Odisha identified six vulnerable districts. These preparations aim to move people away from danger, protect essential services and restore them quickly after the storm passes.

The IMD forecast Cyclone Arnab to cross the Andhra Pradesh and Yanam coasts near Yanam, between Bapatla and Visakhapatnam. The article gives October 28 as the expected landfall date, describing it as Wednesday morning. Another forecast in the report says the crossing could occur by Tuesday afternoon, showing that the timing was being closely monitored.

Arnab was centred over the east-central and adjoining west-central Bay of Bengal at 5:30 am Monday. It was around 650 kilometres east-southeast of Visakhapatnam and moving westwards at 15 kmph. The IMD expected it to intensify into a severe storm and then a very severe storm.

Forecast sustained winds were 115–125 kmph, with gusts up to 140 kmph. Those winds explain the high alert. Andhra Pradesh, Odisha, Telangana, Chhattisgarh and Puducherry prepared for heavy rain and possible disruption. Fishermen were told to stay ashore from October 26 to 29.

The Centre placed Andhra Pradesh, Odisha, Telangana, Chhattisgarh and Puducherry on alert. The main coastal zone was Andhra Pradesh and Yanam, where Arnab was expected to cross near Yanam. Odisha also prepared six southern districts: Ganjam, Gajapati, Rayagada, Malkangiri, Koraput and Nabarangpur. Cyclone warning signals were raised at nine ports across Tamil Nadu and Puducherry.

A cyclone’s effects do not stop at its landfall point. Its rain bands can spread over a broad area, while strong winds and coastal squalls can affect distant districts. The IMD forecast heavy rain in Telangana and Chhattisgarh, and rainfall in West Bengal, Jharkhand, Bihar, eastern Uttar Pradesh, Vidarbha and eastern Madhya Pradesh. The Andaman Islands were also expected to receive rain.

West Bengal’s coast faced squally winds of 35–45 kmph, gusting to 55 kmph. Heavy rain was forecast in several districts, with a landslide warning for Darjeeling. These wider effects explain why states far from Andhra’s coast were asked to remain vigilant.

Arnab’s strongest winds could damage houses, uproot trees and bring down electric poles. The storm could also interrupt roads, rail services, communications and other essential systems. Heavy rain may cause waterlogging and flooding, while hill districts such as Darjeeling faced a landslide warning. People in coastal villages, low-lying areas and fragile homes would face particular danger.

The article gives concrete signs of these risks. Andhra Pradesh kept 25,000 electric poles and other materials ready for possible power disruptions. Authorities planned to shift pregnant women nearing delivery to hospitals. Odisha restricted access to hills, waterfalls and dams in six vulnerable districts. Fishermen were told to return to shore because sea conditions would become dangerous.

Rain and flooding can damage standing crops, fields, livestock and stored food, although the article does not identify specific crops. Rescue teams and control rooms were prepared to protect residents and restore essential services. The storm’s effects could therefore reach homes, transport, electricity, agriculture and local economies well beyond landfall.

The IMD monitored Arnab’s position, movement, strength and expected rainfall. It issued forecasts and warnings so governments could act early. The National Disaster Management Authority and Ministry of Home Affairs coordinated with states. A National Crisis Management Committee meeting reviewed preparedness and relief arrangements, with safety and rapid restoration of essential services as priorities.

NDRF and SDRF teams were deployed, while extra personnel remained on standby. The Army, Navy, Air Force and Coast Guard kept rescue and relief teams ready. Andhra Pradesh positioned 10 NDRF teams, created district-level control rooms and planned regular alerts for coastal villages. Odisha placed NDRF, ODRAF, fire services and police in vulnerable areas.

Local authorities also prepared practical measures. Fishing boats were ordered back to shore. Pregnant women nearing delivery were to be moved to hospitals. Odisha restricted fishing and tourist entry to risky sites. These steps reduce exposure before the storm, while rescue teams and stored materials support recovery after winds and rain cause disruption.

Fishermen were advised not to venture into the sea from October 26 to 29. Cyclones generate dangerous winds, high waves and rapidly changing conditions, making small boats especially vulnerable. A boat far offshore may be unable to outrun the storm or reach shelter. Staying ashore removes one of the most direct life threats before conditions worsen.

The article describes several other protective measures. Andhra Pradesh asked fishing boats to return, alerted coastal villages and prepared to move pregnant women to hospitals. Odisha prohibited fishing and restricted tourists from hills, waterfalls and dams. District control rooms, regular warnings and rescue teams help officials identify danger and respond quickly.

Authorities also positioned NDRF, SDRF, ODRAF, fire services and police, while the armed forces kept relief teams ready. Andhra Pradesh stored 25,000 electric poles and other materials. Together, these measures limit exposure, support evacuation and speed the restoration of power and essential services after the cyclone.

Tropical cyclones form when warm ocean water heats moist air above it. The air rises, lowering pressure near the surface. More warm, moist air then flows inward and rises, releasing heat as water vapour condenses into clouds. Earth’s rotation helps the system begin spinning, while organized thunderstorms can develop around its centre.

If the storm remains over sufficiently warm water, this cycle can intensify. Lower pressure draws in faster winds, and condensation releases more heat, strengthening the circulation. Rainbands produce heavy rainfall, while the pressure difference around the storm creates powerful winds. Land, cooler water and disruptive upper-level winds can weaken the system.

The article reports Arnab intensifying over the Bay of Bengal, moving westwards at 15 kmph. The IMD expected it to become severe and then very severe, with 115–125 kmph winds and gusts to 140 kmph. The article itself does not explain cyclone formation, so this scientific background comes from established meteorology.
