More rains are likely to drench Bangladesh in the next 24 hours, the weather department said Saturday.

Light to moderate rain or thundershowers accompanied by temporary gusty wind is likely to occur at a few places over Khulna, Barishal, Chattogram and Sylhet divisions and at one or two places over Rangpur, Rajshahi, Dhaka and Mymensingh divisions with moderately heavy falls at isolated places over the country, according to the Bangladesh Meteorological Department (BMD).

Meanwhile, the Flood Forecasting and Warning Centre of the Bangladesh Water Development Board said the flood situation in the Sylhet, Sunamganj, Netrokona, Kishoreganj and Brahmanbaria districts may improve in the next 24 hours.

The situation in the flood-prone low-lying Kurigram, Gaibandha, Bogura, Serajganj, Tangail and Jamalpur may also improve.

According to the numerical weather forecast of meteorological agencies, except Teesta Basin, heavy to very heavy rainfall inside Bangladesh and different upstream Indian regions is unlikely in the next 48 hours.

During the same period, there is a chance of medium to heavy rainfall in the Sub-Himalayan West Bengal (Jalpaiguri and Sikkim).

So, the water level of the Teesta River may remain close to the danger level, the Flood Forecasting and Warning Centre said.

Meanwhile, the weather department recorded 24mm rainfall - the highest - in Hatiya in the last 24 hours till 6pm Saturday.

The mercury reached 35.5 degrees Celsius - the highest - in Sayedpur, while the minimum temperature was 24 degrees in Teknaf.

Day and night temperatures may remain nearly unchanged, the BMD said.
