A low-pressure system is likely to form in the Bay of Bengal, bringing the possibility of heavy rainfall across several districts of South Bengal between October 23 and October 26, according to the Alipore Meteorological Department. The forecast comes just a week before Kali Puja celebrations, raising concerns about potential disruptions.
Weather agencies, including private forecasters, have suggested that this low-pressure area may intensify into a deep depression and potentially transform into a cyclone. Some agencies speculate that if this system strengthens into a cyclone, it could be named ‘Dana,’ as assigned by Qatar.
Current Weather Conditions
The Alipore Meteorological Department has reported the formation of a cyclonic circulation over the central Andaman Sea, currently located at an altitude of 5.8 kilometers above sea level. The system is expected to develop into a low-pressure area over the east-central Bay of Bengal and the northern Andaman Sea by October 21.
This low-pressure system is likely to move northwestward and gain strength, potentially evolving into a depression by October 23. From that date, various districts in West Bengal could experience light to moderate rainfall, with isolated instances of heavy rainfall in certain regions.
Districts Likely to be Affected
The districts most likely to be affected include East Midnapore and South 24 Parganas, where heavy rains are forecasted. However, the rainfall will not be evenly distributed, and only some areas within these districts may experience significant precipitation.
According to private weather agencies, the low-pressure system may intensify further into a deep depression or even develop into a cyclone over the Bay of Bengal. If this occurs, the system could bring more severe weather conditions, including strong winds and heavy rainfall, as it approaches the coast of West Bengal.
Cyclone ‘Dana’ and Potential Impact
Should the system transform into a cyclone, it will be named ‘Dana,’ a designation assigned by Qatar as part of the World Meteorological Organization’s cyclone naming convention. Such a development would likely lead to heightened rainfall, with stronger winds and possible flooding in vulnerable areas.
The Meteorological Department has also issued warnings to fishermen, advising them to avoid venturing into the sea from October 22 to October 24, as the waters may become dangerous due to rough conditions. Wind speeds in the central and southern Bay of Bengal could range between 35 to 45 km/h, with gusts reaching up to 55 km/h.
From October 23 onwards, gusty winds are also expected to impact the northern Bay of Bengal, causing further disruption. Fishermen are advised not to travel to these areas until further notices are issued.
Precautionary Measures
Given the potential for severe weather, local authorities are monitoring the situation closely. Warnings have been issued to residents in coastal districts to remain vigilant and take necessary precautions.
While the exact trajectory of the system remains uncertain, preparations are underway to minimize damage and ensure safety. If the low-pressure system develops into a cyclone, more stringent measures may be introduced to protect communities in the affected regions.
As the situation continues to evolve, updated forecasts and advisories will be issued in the coming days.
