The Met office says it hasn't seen such erratic pattern of monsoon, which has caused about 40 percent more rainfall this year than the average recorded over the last 10 years. 'Climatic change has caused a spike in variability,' says a top weather expert.

People's sufferings continue as rains keep on pouring in Dhaka. Several streets remain inundated, causing acute gridlock. According to Met office, rain may fade later in the day.

It has been raining in Dhaka since Saturday. Sometimes rains came down heavier after slight relapses. But had it come a little earlier today, many of a Merul Badda slum might not lost their belongings in a devastating fire.

After a slight relapse, the seasonal downpour is expected to come down heavier in the coming days in Dhaka and most places of the country.

Heavy rain is likely to continue at most places of the country except Rangpur till Monday evening, according to met officials.

Just several hours of rain cripples the life in Dhaka as different parts of the capital went under ankle to knee-deep water, thanks to poor drainage system.

Different parts of the country including Dhaka and Chittagong may experience heavy rainfall with thunder showers in the next 24 hours.

Usually what is seen during monsoon, most of the key points in Chittagong city goes down underwater in last night’s downpour.
