Live: Andhra, Odisha on high alert, begin evacuations; Jharkhand, UP to feel impact

A severe cyclonic storm is a strong tropical cyclone that can produce destructive winds, intense rain, rough seas and coastal flooding. Its danger comes from several hazards arriving together, not only from wind speed. Authorities therefore prepare coastal and inland districts before the storm reaches land.

The article places Arnab’s expected landfall near Yanam, along the Andhra Pradesh-Yanam coast, on October 28. IMD Hyderabad Director Stella said winds could reach 125–135 kmph, with gusts up to 150 kmph. Andhra’s Home Minister separately warned of 120–140 kmph winds during landfall.

The forecast has triggered high alerts in Andhra Pradesh and Odisha. Evacuations, shelters, medical beds, control rooms and rescue teams are being prepared. The storm is already producing rain and rough seas in places such as Ganjam and disrupting flights near Vijayawada. Residents should follow official advisories as the landfall date approaches.

Arnab is expected to bring extremely strong winds along the Andhra Pradesh coast. The article gives forecasts of 125–135 kmph winds, gusting to 150 kmph, and another warning of 120–140 kmph during landfall. These speeds can damage structures, uproot trees and make travel dangerous. The article does not provide a numerical rainfall total.

It does identify areas facing heavy rain. Telangana may receive heavy to very heavy rainfall in isolated places, including Mulugu, Bhadradri Kothagudem, Mahabubabad and Khammam. Hyderabad is expected to get light rain. Odisha’s Ganjam district has already seen rainfall and rough seas.

Andhra Pradesh has prepared 2,131 cyclone shelters, 1,274 ambulances and 8,281 emergency beds. Authorities also shifted 1,351 pregnant women to hospitals. NDRF and SDRF teams are ready, and control rooms operate at every mandal headquarters. These resources support evacuation, medical care, rescue and rapid communication.

Coastal residents are being moved because Arnab could produce dangerous winds, rising waves and a storm surge. Seawater may enter low-lying villages and other vulnerable areas. Evacuation places people in designated relief centres before roads, power supplies or communications become harder to use.

Pregnant women were shifted to hospitals so they can receive medical attention without travelling during the storm. The article reports that 1,351 pregnant women were moved. Fishermen were told not to enter the sea because the storm has made waters rough and could create powerful winds, waves and dangerous boat conditions.

These steps reduce exposure before landfall. Andhra Pradesh has secured fishing boats, prepared shelters, ambulances and emergency beds, and opened control rooms. Coastal traffic near Kakinada has already been disrupted by rising waves. People should move when instructed and rely on official advisories rather than rumours.

A storm surge is a temporary rise in sea level caused mainly by a cyclone pushing seawater toward the coast. It is different from ordinary waves and tides because it can send a broad mass of seawater inland. The greatest danger occurs in low-lying coastal areas, where water can move into villages quickly.

The article warns that Arnab could cause a severe surge extending up to 100 km on either side of the expected landfall zone. That seawater could inundate coastal villages and other vulnerable areas. Rough seas and rising waves are already affecting coastal traffic near Kakinada, showing why authorities are concerned.

Kakinada Port has received the No. 10 Great Danger Signal. Other ports, including Visakhapatnam, Gangavaram, Machilipatnam and Nizampatnam, have received No. 8 signals. Residents in threatened areas are being urged to move to relief and rehabilitation centres before flooding begins.

Port danger signals are formal warnings about the threat a cyclone poses to a port and nearby coast. They prompt authorities to restrict marine activity, secure boats and prepare for dangerous winds, waves and possible surge. In the article, Kakinada received the No. 10 signal, while four other ports received No. 8 signals.

Cyclone shelters provide safer temporary accommodation for evacuated residents. Control rooms collect information, issue instructions and coordinate local action. The article says Andhra Pradesh established control rooms at every mandal headquarters. NDRF and SDRF teams are specialist emergency forces that can support evacuation, rescue and relief operations.

These systems work together before and during landfall. Officials remove roadside hoardings, secure fishing boats, prepare ambulances and keep emergency beds ready. Odisha’s meeting brought together district officials, NDRF, ODRF and fire services. Their coordination helps communities respond faster as conditions change.

Cyclone effects do not stop at the coastline. After landfall, a storm can continue carrying moisture inland while its wind circulation spreads over a wide region. Rain bands may produce intense downpours away from the centre. Winds can also remain strong enough to damage trees, buildings and infrastructure.

The article says Telangana may receive heavy to very heavy rainfall in isolated areas, including Mulugu, Bhadradri Kothagudem, Mahabubabad and Khammam. Hyderabad is expected to receive light rain. The headline also says Jharkhand and Uttar Pradesh will feel the cyclone’s impact, though it gives no detailed forecast for those states.

This wider reach matters because inland flooding, blocked roads and disrupted services can follow coastal landfall. Forecast offices and local authorities must therefore monitor conditions beyond the coast. People should follow advisories even if they live far from the expected landfall zone, since rain and winds may arrive later.

The source article does not explain cyclone formation. In general, a tropical cyclone begins over very warm ocean water, which adds heat and moisture to air near the surface. That air rises, pressure falls, and surrounding air moves inward. Earth’s rotation helps the system develop a rotating circulation. If conditions remain favourable, the storm can strengthen.

The Bay of Bengal is especially vulnerable because it regularly supports tropical storms and has long, low-lying coastal stretches. Dense coastal settlements, fishing communities and important ports can be exposed to powerful winds, heavy rain and seawater pushed inland. A cyclone’s danger therefore includes both direct wind damage and flooding.

Arnab illustrates these risks. Ports issued high danger signals, coastal traffic near Kakinada was disrupted, and residents were urged to move to relief centres. Andhra Pradesh and Odisha are coordinating evacuations and rescue preparations. The article’s warnings show why coastal readiness is essential before landfall.
