Well-Marked Low-Pressure Area Forms Over West-Central Bay of Bengal; Set to Intensify into Deep Depression Within 48 Hours

A well-marked low-pressure area has formed over the west-central Bay of Bengal and is tracking west-northwestward. Meteorological agencies warn the system is expected to intensify into a depression within 24 hours and could further escalate into a deep depression over the subsequent 24 hours, bringing rough sea conditions and heightened rainfall alerts along adjacent coastal regions.

Well-Marked Low-Pressure Area Forms Over West-Central Bay of Bengal; Set to Intensify into Deep Depression Within 48 Hours

BHUBANESWAR / VISAKHAPATNAM, KALINGA SAMBAD

Weather monitoring authorities have detected the formation of a well-marked low-pressure area over the west-central Bay of Bengal, signaling an active monsoon phase and imminent weather disruption across coastal and interior districts.

According to meteorological bulletins, the weather system has been tracking in a west-northwestward direction under favorable environmental conditions, including elevated sea surface temperatures and supportive upper-air divergence. Forecasters have indicated that the system is likely to concentrate into a depression within the next 24 hours. Numerical weather prediction models further point to sustained intensification, with strong indications of the system upgrading into a deep depression over the subsequent 24 hours.

Projected Trajectory and Intensification

The system's current west-northwestward trajectory places coastal belts along the east coast on alert. As the low-pressure zone transitions into a depression and potentially a deep depression, atmospheric pressure over the marine region will drop, accompanied by rising surface wind speeds reaching between 45 and 65 km/h over the central and northern Bay of Bengal.

State disaster management authorities and district administrations across potentially vulnerable zones are closely monitoring official bulletins. Standard operating procedures are being reviewed to address localized waterlogging, flash flooding in low-lying pockets, and potential disruptions to transport and communication links.

Warnings and Advisory for Fishermen

Given the projected trajectory and rapid consolidation of the system:

Marine Advisory: Fishermen already out at sea have been advised to return to coastal harbors immediately. Deep-sea fishing operations across the west-central and adjoining northwest Bay of Bengal are suspended until further notice.

Port Alerts: Minor ports along the eastern coastline have been instructed to keep cautionary distance signals ready as squally winds and surging wave heights build over maritime trade routes.

Agricultural & Civic Precaution: Farmers in low-lying delta tracts have been urged to harvest mature standing crops and clear drainage channels, while civic bodies in coastal urban settlements have been placed on standby for emergency pumping operations.

Further updates on the definitive landfall point, wind speeds, and targeted rainfall zones will be released in successive meteorological bulletins as the system organizes into a depression.
