Online Desk  : A flood threat has been issued for four districts in Bangladesh—Sherpur and Netrokona in Mymensingh division, and Sunamganj and Sylhet in Sylhet division—within the next 24 hours, as river water continues to rise above danger levels due to heavy upstream rainfall. According to meteorological sources, continuous torrential rains in Meghalaya and Assam in neighboring India, coupled with intermittent rainfall over the last four days in Sherpur, have caused a rapid surge in local river levels. The Chellakhali River in Sherpur is already flowing dangerously high, currently recorded at 106 centimeters above the danger mark as of 10 a.m. Tuesday—up from 39 centimeters just 12 hours earlier.

Mustafa Kamal Palash, chief meteorologist at private weather portal Meghalaya.com, warned that flash floods originating from the hills are likely to affect the rivers in these four districts within the day. “There is a high probability of moderate to heavy rain over Rangpur, Mymensingh, and Sylhet divisions from Tuesday noon to Wednesday noon,” Palash stated. The Sherpur office of the Water Development Board (PAUBO) confirmed the sudden rise in the Chellakhali River’s water level due to fresh upstream runoff and ongoing rainfall in the area.

Palash, in a Facebook update, noted that radar images from the Bangladesh Air Force show continuous thunderstorm activity passing over Rangpur, Mymensingh, and Sylhet divisions from the northwest toward the northeast. Rainfall has also begun in parts of the Barisal and Chattogram divisions, indicating a broader weather system in motion. The meteorologist further warned of a heightened risk of repeated thunderstorm activity across the flood-prone districts between 11:30 a.m. and 6 p.m. today, urging residents and authorities to remain on alert. Emergency response teams have been placed on standby, and local administrations are monitoring river levels closely to mitigate the impact of potential flash floods and ensure the safety of vulnerable communities.
