A low-pressure system over the central Bay of Bengal is gaining strength and could develop into a powerful cyclone within the next few days, according to the private weather monitoring group Bangladesh Weather Observation Team (BWOT)
The system could make landfall along India’s eastern coast between the evening of October 27 and the morning of October 28, according to BWOT’s preliminary forecast. However, its track, intensity and landfall timing may change.
In separate updates on Friday, October 23, the Bangladesh Meteorological Department (BMD) and BWOT warned of possible rough seas, heavy rainfall in parts of Bangladesh and potential damage to agriculture.
BWOT said the system could intensify into a well-marked low within the next 12 to 24 hours and develop into a depression or deep depression over the following 48 hours. It could become a strong cyclone within 72 hours, the group forecast.
The BMD’s observations suggest that the likelihood of the system making a direct hit on Bangladesh is currently low. However, BWOT warned that its indirect effects could bring significant rainfall to several parts of the country.
Strong rain bands may become active in different regions between October 27–28 and November 1–2, potentially causing heavy rainfall in some areas. The amount and distribution of rain will depend on how the weather system develops.
With rough seas expected in the northern Bay of Bengal, the BMD has advised fishing boats and trawlers operating in deep waters to proceed with caution. Fishermen have also been urged to follow the latest weather bulletins and instructions from the authorities.
BWOT warned that heavy rain could damage agricultural crops, particularly mature paddy. Rain-soaked rice may rot or sprout, while strong winds and waterlogged fields could cause plants to fall over.
Farmers have been advised to harvest mature paddy and move it to safe locations by October 26. Those planning to cultivate winter vegetables or prepare seedbeds should wait until the rain subsides.
Farmers with existing winter crops and vegetables have been urged to clear drainage channels to prevent waterlogging. BWOT also recommended covering harvested crops, seeds and fertiliser with polythene and making advance arrangements to transport crops quickly.
Authorities and farmers should monitor updated forecasts as the system develops, since warnings may change with shifts in its track and intensity.
