After ravages of July, another flooding in mid-August

The country is likely to be visited by another round of flooding in mid-August in the Brahmaputra and the Meghna basins, according to a long-range forecast by the Bangladesh Meteorological Department (BMD).
It is likely to happen due to rain in the upper catchment on which the flow of the Brahmaputra and rivers in the Meghna basin depends, BMD director Shah Alam told The Independent yesterday.
It would be normal seasonal flooding as the country may experience a little extra rain against the background of the July rainfall which was 65 per cent higher than the normal average, he said.
The rainfall is likely to go up spurred by 1-2 monsoon low pressures brewing in the Bay of Bengal this month, the BMD director said, quoting the August forecast that was issued after a meeting of experts from the BMD, WDB and SPARSSO held at the met office on Sunday.
The monsoon arrived this year in early June on the wings of seasonal low pressures in the Bay, resulting in 23 per cent more than average rainfall triggering flash floods in the south-eastern hilly regions. This was followed by 65 per cent higher than average rainfall in July, caused by a low pressure changing into a deep depression that brewed a cyclonic storm, resulting in the second spell of flooding in the hills of Bandarbans and below at Cox’s Bazar.
In July, instead of the normal 379mm, Dhaka division had 555mm of rainfall. Chittagong 1,322mm (normal 720mm).
In contrast, Rangpur division had 266mm, less than the normal average of 416mm. Rajshahi division had 360mm. Khulna recorded 746mm instead of the normal average of 341mm. Barisal recorded 861mm, higher than the normal average of 519mm.
The rain pattern in July was not abnormal, Shah Alam said. It was due to the cyclonic storm that spun off a land depression dumping rain between July 26 and 31. The rain instead of going towards the Himalayas fell flat on the plains of Bangladesh, the BMD director explained the causes of the cyclonic storm induced rainfall. This time its going to be normal rainy days, he added.
