A low-pressure system over the Bay of Bengal has intensified steadily and is poised to upgrade into a deep depression within the next several hours. Moving steadily in a west-northwestward direction, this formidable weather system is projected to cross the coastline between northern Andhra Pradesh and southern Odisha, specifically between Visakhapatnam and Gopalpur, between the night of September 23 and the early morning hours of September 24. As the circulation pulls in moisture and charges toward the coast, meteorologists have warned of severe weather disruptions, torrential downpours, gale-force winds, and significant local flooding across coastal belts and adjacent inland regions.
As of 8:30 AM on Tuesday, the system was firmly centered over the west-central and adjoining northwest Bay of Bengal. Observational coordinates placed it roughly 200 kilometers southeast of Gopalpur in Odisha, 210 kilometers south of Puri, about 200 kilometers east-southeast of Kalingapatnam in Andhra Pradesh, and approximately 290 kilometers east of Visakhapatnam. The trajectory and strengthening pace of this vortex indicate that coastal habitats will face deteriorating atmospheric conditions over the subsequent 48 to 72 hours, prompting state disaster management networks to gear up for emergency protocols.
Severe Downpours and Gales Set to Pound Odisha
Odisha stands directly in the forward path of the advancing depression, placing its coastal and interior districts under maximum weather vulnerability. Heavy to very heavy rainfall, with isolated patches experiencing extremely heavy precipitation, is forecast across the state from September 22 through September 24. A broader spell of widespread rain, squally showers, and persistent thundershowers will envelop the state between September 22 and September 26, with wet conditions potentially spilling into September 27 and September 28 in several pockets.
Alongside unrelenting rain, strong thunderstorms will batter coastal Odisha from September 22 to September 24. Wind velocities during this critical phase are projected to hover between 50 and 60 kmph, occasionally producing sharp gusts of up to 70 kmph. These squalls have the potential to dislodge loose structures, topple billboards, uproot weak trees, and damage standing crops. Given the rough-to-turbulent state of the sea, marine advisories have strictly urged fishing communities and trawler operators to avoid venturing into the waters and to tether craft securely along sheltered harbours.
High Alert Across Andhra Pradesh and Telangana Amid Rising Wind Speeds
The adjoining coastline of Andhra Pradesh and the enclave of Yanam are equally braced for intense atmospheric impacts. Widespread rainfall is predicted for coastal Andhra Pradesh from September 22 to September 25, with isolated spells of extremely heavy downpours scheduled for September 22 and September 23, followed by very heavy rains on September 24. The turbulence has already manifested on the ground, with squally conditions emerging around coastal Andhra Pradesh and Yanam on September 22, where sustained speeds could climb to 50-60 kmph with gusts touching 70 kmph by the evening. Wind speeds will further elevate to 55-65 kmph from the morning of September 23 through the evening of September 24.
In neighboring Telangana, the impact will peak across September 23 and September 24, when the meteorological agency anticipates extremely heavy rainfall across several tracts. Pockets of very heavy rain are also forecast for September 22 as well as September 25-26. Both coastal Andhra Pradesh and Telangana must contend with gale-force gusts reaching up to 70 kmph over September 23-24, creating an immediate danger of tree falls, electrical line snaps, and localized water logging across urban and rural transport corridors.
Dangerous Conditions at Sea as Bay of Bengal Sees 75 kmph Gusts
The marine expanse of the Bay of Bengal remains extraordinarily rough as the storm center churns through maritime passages. Over west-central and adjoining northwest sectors of the Bay, squally winds blowing at 45 to 55 kmph, with peak gusts hitting 65 kmph, are already underway. Wind strength will notch up from the evening of September 22 to 50-60 kmph, gusting up to 70 kmph, before escalating to sustained levels of 55 to 65 kmph with fierce gusts reaching 75 kmph between September 23 and the evening of September 24.
Outlying marine sectors across northern and southern parts of the Bay of Bengal will similarly witness energetic winds clocking 45-55 kmph beginning the morning of September 22, likely accelerating to 50-60 kmph on September 23. The harsh marine environment poses extreme risks to coastal shipping, port cargo operations, and artisanal fishing, requiring complete operational vigilance from port authorities along the eastern seaboard.
Rain Belt Expands into West Bengal, Jharkhand, and Bihar
As the deep depression progresses inward, its moisture-laden arms will trigger substantial precipitation over eastern India. Widespread rain will sweep through Gangetic West Bengal and Odisha between September 22 and September 26. Jharkhand will experience widespread wet weather from September 22 to September 27, while Bihar will enter a widespread rain cycle from September 24 to September 27. The northern hills of Sub-Himalayan West Bengal and Sikkim will similarly witness persistent downpours between September 23 and September 27.
Heavy showers are expected across Gangetic West Bengal on September 22, September 23, and September 25, while Sub-Himalayan West Bengal and Sikkim will face very heavy spells on September 25. In Jharkhand, heavy rain is slated for September 23 alongside September 25 and September 26, accompanied by a specific advisory for moderate to severe lightning strikes on September 22. In Bihar, heavy showers are forecast on September 23 and across September 26-27, with isolated locations receiving very heavy falls on September 24 and September 25.
Central India on Vigil: Torrential Rains in Chhattisgarh, Vidarbha, and Madhya Pradesh
The westward trek of the depression will dump immense volumes of water into central Indian watersheds. Chhattisgarh is on notice for heavy to very heavy rainfall across September 23 and September 24, elevating the risk of flash flooding in catchments and inundated roads in low-lying towns. Meanwhile, eastern Madhya Pradesh and the Vidarbha region are set to register intensified rainfall spells from September 22 through September 27. Authorities have instructed the public to closely track weather updates and observe safety advisories issued by local district administrations to navigate the stormy sequence safely.
