The Bay of Bengal is witnessing an intensification of cyclonic activity as Cyclone Arnab continues to develop over the east-central and adjoining west-central parts of the sea. According to the India Meteorological Department's (IMD) bulletin issued on October 26, 2026, the system is expected to strengthen further over the next 24–48 hours and may intensify into a Very Severe Cyclonic Storm by October 27. The storm is forecast to approach the Andhra Pradesh coast on the morning of October 28, bringing the threat of extremely strong winds, heavy rainfall and coastal inundation. Residents of vulnerable coastal areas are advised to closely follow official weather updates and local administration advisories.
According to the IMD's assessment based on observations at 5:30 AM IST on October 26, Cyclone Arnab was centred over the east-central and adjoining west-central Bay of Bengal, near latitude 15.4°N and longitude 88.9°E. 590 km northwest of Sri Vijaya Puram in the Andaman and Nicobar Islands. 610 km southeast of Gopalpur in Odisha. 650 km east-southeast of Visakhapatnam in Andhra Pradesh. The system moved westward at a speed of approximately 15 kmph during the preceding six hours before intensifying from a deep depression into Cyclone Arnab.
The IMD forecasts that Cyclone Arnab will initially move west-northwestwards before strengthening further over the Bay of Bengal. Its expected development over the coming days is as follows:
According to the forecast, the system may cross the Andhra Pradesh and Yanam coast between Bapatla and Visakhapatnam. However, the precise landfall location, timing and peak intensity remain subject to changes in subsequent forecasts.
Wind Speeds May Reach 125 kmph, With Gusts up to 140 kmph:
The approaching cyclone could bring dangerous wind conditions to parts of the Andhra Pradesh coast. The IMD bulletin indicates that, at the time of landfall, the maximum sustained wind speed could reach 115–125 kmph, with gusts up to 140 kmph. Such conditions may damage vulnerable structures, uproot trees, disrupt electricity supplies and affect road and transport services. Coastal communities should remain alert and follow official instructions regarding evacuation and other precautionary measures.
Warm Bay of Bengal Waters May Fuel Cyclone Intensification:
Warm ocean waters and favourable atmospheric conditions are supporting the development of Cyclone Arnab. According to the IMD's technical assessment, sea surface temperatures over the affected parts of the Bay of Bengal are approximately 29–30°C. Warm ocean waters provide energy and moisture that can support tropical cyclone development. Favourable upper-level atmospheric circulation and relatively low to moderate wind shear may also contribute to further intensification. The interaction of these atmospheric and oceanic factors will influence the storm's strength and movement over the coming days.
Cyclone May Weaken After Making Landfall:
IMD's assessment suggests that Cyclone Arnab may gradually weaken after moving inland. Once the system moves over land, reduced access to warm ocean moisture and increased surface friction generally help diminish a cyclone's intensity. However, changes in the storm's direction may also occur after landfall. The influence of an upper-atmospheric trough could encourage the system to turn northwards. Its post-landfall movement and weakening pattern will depend on the prevailing atmospheric conditions.
