Rain and thundershowers are likely to continue at most places in seven divisions in the next 24 hours commencing 6pm Thursday, the Bangladesh Meteorological Department (BMD) said in a forecast.
Most places in Dhaka, Mymensingh, Rajshahi, Khulna, Barishal, Chattrogram and Sylhet divisions and many places over Rangpur division are likely to see rain and thundershowers while some places will be hit by heavy to very heavy falls, the Met Office said.
Due to the well-marked low over the Northwest Bay and adjoining West-central Bay, heavy to very heavy rainfall is likely to occur at places over Rajshahi, Dhaka, Khulna, Barishal, Chattogram, Mymensingh and Sylhet divisions, BMD added.
About the synoptic situation, the well-marked low over west-central Bay and adjoining area moved northwestwards and intensified subsequently into a depression and afterwards into a deep depression over the northwest Bay adjoining area.
It is likely to intensify further.
South-west monsoon has withdrawn from the north-western part of Bangladesh and conditions are favourable for further withdrawal from the remaining parts of Bangladesh.
Monsoon is strong elsewhere over the North Bay.
Day and night temperatures may fall by (1-3)°C over the country.
