Bay of Bengal Low Pressure Expected to Strike Odisha and Andhra Coast as Cyclone by October 28

UPDATE - follow-up to Cyclone brewing as low pressure area forms in east-central, Southeast Bay of Bengal | Live: The weather system over the Bay of Bengal is set to intensify into a cyclonic storm and cross the southern Odisha and northern Andhra Pradesh coast by October 28. According to the India Meteorological Department's Bhubaneswar Met Centre, a low-pressure area over the east-central and adjoining southeast Bay of Bengal persisted at 8.30 a.m. on Friday, October 23, 2026.

Weather Progression and Regional Impacts

The low-pressure system is expected to turn into a depression on Saturday, a deep depression on Sunday, and a full cyclonic storm by Monday morning. K. Naga Ratna, Head of the Amaravati Meteorological Centre in Andhra Pradesh, stated that the system will likely cross the coast in the early hours of October 28 before moving toward Odisha the next day. Meanwhile, the APSDMA listed Konaseema, West Godavari, Krishna, Guntur, Bapatla, Prakasam, and the Rayalaseema districts for rain.

Southern Rains and Wider Studies

Rainfall has also hit other areas, with moderate to heavy downpours predicted across Tamil Nadu and Puducherry until October 26, alongside general moderate rainfall in Chennai. Heavy rains with lightning and thunder lashed Tiruchi and delta districts on Friday evening, slowing down peak-hour traffic. Separately, a new historical climate study published in the IMD journal Mausam revealed that large parts of northern India grew hotter and drier over the past 70 years, extending the dry zone from western Uttar Pradesh into the east, while much of peninsular India became wetter.

Context

Tropical storms frequently form in the Bay of Bengal during the monsoon and post-monsoon seasons, often bringing heavy rainfall and strong winds to India's eastern coastline. Meteorological departments track these low-pressure systems continuously to issue timely warnings for coastal populations and fishermen. Understanding these seasonal weather patterns helps state authorities plan safety measures and evacuations well in advance of a landfall.
