The suffering continues for millions of Bangladeshis as the overall flood situation worsened again on Saturday, with six north-eastern districts - Sylhet, Sunamganj, Netrokona, Kurigram, Lalmonirhat, and Sherpur -continuing to be the worst sufferers.

The situation is particularly dire in the two frontier districts of Sylhet and Sunamganj, where residents have described the 'worst flooding in living memory'. Even experts were at a loss to foresee the sheer pace at which the two districts have been inundated since Thursday, in close concert with record rainfall witnessed just across the border in Mawsynram and Cherrapunji, in India's hilly Meghalaya state, which are known as the wettest places in the world.

On Friday, the Sohra region of Meghalaya's Cherrapunji recorded its third highest rainfall ever in a 24-hour period, with 972.0 mm of rain. It added up to some 2500 mm since Wednesday, its highest 3-day count of rainfall in 27 years.

Mawsynram recorded 1003.6 mm on Friday, its highest ever for a 24-hour period in June. With the waters inevitably destined to make their way down fiercely over the hilly terrain and rivers running downstream into Bangladesh, flooding in Sunamganj and Sylhet was bound to worsen on Saturday, and that is exactly what happened.

The unprecedented flooding inundated an astonishing 80 percent of the territory under Sylhet district, and 90 percent area of Sunamganj, according to Flood Forecast and Warning Center. Sunamganj lost power even earlier, now the grid has shut down in both districts.

At 6am on Saturday , the Surma River was flowing 128 cm above its danger mark in Kanaighat, 77cm above in Sylhet, and 120cm above in Sunamganj, while the Sari River was flowing 67cm above its own danger mark at the same time.

The water levels of the Kushiara and Jadukata rivers in Sunamganj are also well above their danger marks. All of them are transboundary rivers crossing downstream into Bangladesh from India.

A limited number of vehicles were plying on Sylhet- Sunamganj road as large sections of it went under flood water, effectively cutting off the two districts from each other. Besides, the Sylhet-Companiganj-Bholaganj road went underwater, halting road communication.

Authorities were also forced to disconnect gas supply in some flood-hit areas to avoid the risk of a bigger disaster.

The electricity supply to Sunamganj district and its adjacent areas had to be disconnected to avoid accidents as Chhatak and Sunamganj grid substations went under flood water.

Meanwhile, more than one lakh people of Chhatak upazila remained under flood water till Saturday afternoon. People of the upazila do not get any kind of assistance including relief from the administration.
