Bangladesh’s Meteorological Department has instructed four seaports to display local warning signal No. 3 after a low-pressure area formed over the northern Bay of Bengal and the adjoining West Bengal-Bangladesh coast. The information was issued in a notice signed by meteorologist Dr Muhammad Abul Kalam Mallik at about 10:15am on Wednesday, August 12, 2026.

The notice said the low-pressure system may intensify. Gusty winds could sweep across the northern Bay of Bengal and Bangladesh’s coastal areas as a result. The warning was issued because of the risk of such winds affecting maritime and coastal conditions.

The directive applies to the seaports of Chattogram, Cox’s Bazar, Mongla and Payra. Fishing boats and trawlers operating in the northern Bay of Bengal have also been asked to remain close to the coast and move carefully until further instructions are issued. The notice reiterated the possibility that the low-pressure area could become more concentrated and bring gusty winds over coastal areas.
