Bangladesh’s Meteorological Department said rainfall is likely to increase across the country from August 13 to 19 as a new low-pressure area may form over the northwestern Bay of Bengal by Wednesday. Meteorologist AKM Nazmul Haque said Wednesday may be relatively dry, though rain will continue in varying amounts during the monsoon season. Heavy rain is possible in some areas.

Coastal areas are expected to receive more rainfall during the period. Haque said heavy to very heavy rain may occur, but the likelihood of prolonged very heavy rainfall similar to earlier episodes is lower. In the 24 hours ending at 6 p.m. Tuesday, Dhaka recorded 35 millimetres of rain, while Gopalganj recorded the highest total, 61 millimetres.

Lower rainfall contributed to warmer, humid conditions nationwide on Tuesday. Rajarhat in Kurigram recorded the highest temperature at 36.4 degrees Celsius, while Dhaka recorded 35.5 degrees. Forecasts said several divisions could receive rain or thunderstorms with gusty winds on Wednesday and Thursday, with moderate heavy rainfall possible in isolated places. The department also said rainfall tendency may rise over the following five days.
