175mm rainfall, official report says 7mm
Questions have been raised over the accuracy of official rainfall data after the Department of Agricultural Extension (DAE) recorded 175 millimetres of rainfall in Lalmonirhat over a 24-hour period, while the Rangpur Meteorological Office reported only 7 millimetres for the same timeframe.
According to the Lalmonirhat DAE, 175mm of rainfall was recorded in Lalmonirhat Sadar upazila between 9:00 am on Sunday and 9:00 am on Monday, marking the highest rainfall recorded in the district this year. The previous highest rainfall was 165mm, recorded on June 15.
However, the Rangpur Meteorological Office reported that only 7mm of rainfall had been recorded during the same 24-hour period, triggering criticism and concern among local residents over the discrepancy.
Responding to the issue, acting officer of the Rangpur Meteorological Office Mostafizur Rahman said the office's rainfall measuring instrument had been out of order for nearly two months.
"We have already informed the concerned authorities about the malfunction. We publish the data received through our computer system, which showed 7mm of rainfall during the period," he said.
Residents said Lalmonirhat experienced intermittent moderate to heavy rainfall throughout Sunday, with continuous heavy rain from evening until midnight causing waterlogging in several low-lying areas.
Officials said rain gauges are installed at the agriculture offices in all five upazilas of the district, where rainfall is measured manually. These data play an important role in agricultural planning, fisheries, disaster management and other public services.
Sources also said that under a project of the Bangladesh Meteorological Department, rainfall and temperature monitoring equipment had been installed at several locations across northern Bangladesh, including the Lalmonirhat Sadar Upazila Parishad office. However, officials could not confirm the current status or location of that equipment.
As Lalmonirhat has no dedicated meteorological office, the district depends on the Rangpur Meteorological Office for official weather information, including rainfall and temperature data.
Local residents and stakeholders have urged the authorities to promptly repair the faulty equipment and ensure accurate weather data, stressing that reliable meteorological information is crucial for disaster preparedness, flood forecasting and public safety.
