Maritime ports of Chattogram, Cox’s Bazar, Mongla and Payra have been advised to keep local cautionary signal no. 3 hoisted as the monsoon depression over India’s West Bengal-Bihar and adjoining area moved west-northwestwards and now lies over north Chhattisgarh and adjoining area. It is likely to move in a west-northwesterly direction further and weaken gradually into a well-marked low, said a special bulletin of the Met office on Thursday (August 03, 2023). Maritime ports asked to hoist cautionary signal 3 Under its influence steep pressure gradient persists over north Bay and adjoining coastal areas of Bangladesh.

The maritime ports of Chattogram, Cox’s Bazar, Mongla and Payra have been asked to hoist at the mast local cautionary signal No 3 to alert vessels of a possible squall. The weather office's advisory for cautionary signal No 3 -- which means a depression has formed and may affect the port later -- comes in the wake of the formation of a low pressure area over the west-central Bay and the adjoining Northwest Bay. It is likely to intensify further, the  Bangladesh Meteorological Department (BMD) said in a special bulletin on Saturday morning. Under its influence, a deep convection is taking place over the North Bay and adjoining areas. Squally weather may affect the maritime ports, the North Bay and the adjoining coastal areas of Bangladesh.

They have also been advised not to venture into the deep sea.

Daylong drizzle disrupted life in the capital and some other parts of the country as cyclonic storm ‘Jawad’ weakened into a deep depression over the Bay of Bengal on Sunday. The day started with a cloudy sky in the capital and people who stepped out of home in the morning without preparation for rain suffered immensely.

Traffic constables were seen passing busy time to control traffic as drizzles caused traffic chaos in some areas in the morning. According to a Met office bulletin, “Light to moderate rain or thunder showers accompanied by temporary gusty wind is likely to occur at most places over Khulna, Barishal, Chattogram & Dhaka divisions; at many places over Rajshahi, Mymensingh & Sylhet divisions and at one or two places over Rangpur division with moderately heavy falls at isolated places over the country.” Night temperature may remain nearly unchanged and day temperature may fall slightly over the country. Signal No 3 at maritime ports The maritime ports of the country have been advised to hoist local cautionary signal number three as the deep depression over west-central bay and adjoining northwest bay moved north-northeastwards and lies over northwest bay and adjoining west-central bay. It was centred at 06 am on Sunday about 875 kms southwest of Chattogram port, 855 kms southwest of Cox's Bazar port, 695 kms south-southwest of Mongla port and 725 kms south-southwest of Payra port.  It is likely to move further in a north-northeasterly direction and weaken gradually. Maximum sustained wind speed within 48 kms of the deep depression centre is about 50 kph rising to 60 kph in gusts or squalls. Sea will remain rough near the centre of the deep depression. Under the influence of the peripheral effect of the deep depression, deep convection is continuing over north Bay and adjoining coastal areas of Bangladesh.
