Dhaka records highest 206mm rainfall in 24 hours

Dhaka experienced the country's highest rainfall of 206 millimetres in the 24 hours till 9:00am today.

Duty Forecasting Officer Kazi Jebunnesa of the Bangladesh Meteorological Department (BMD) said the capital witnessed 132 millimetres of rain in just six hours, between midnight and 6:00am, and 206 millimetres in the past 24 hours — the highest in the country.

The met office has forecast heavy rainfall across the country and issued local cautionary signal No. 3 at maritime ports due to a low pressure, she said.

Although the intensity of rain eased slightly in the morning, rainwater inundated several roads in the capital, disrupting movement.

According to the BMD, there is a possibility of heavy rain in different areas of Rangpur, Rajshahi and Mymensingh divisions today. Heavy rain has already begun in parts of North Bengal, including Bogura.

Meteorologists define heavy rainfall as precipitation between 44 and 88 millimetres in a day.

This spell of rain, accompanied by gusty winds and lightning, may continue in parts of the country until October 4, Jebunnesa said.

The met office added that due to the influence of a well-marked low over the west-central Bay and adjoining areas and an active monsoon, heavy to very heavy rainfall is likely to occur at places over Rangpur, Rajshahi, Mymensingh, Dhaka, Khulna, Barishal, Chattogram and Sylhet divisions in the next 72 hours from 9:00am today.

Due to heavy to very heavy rainfall, landslides may occur in hilly areas of Chattogram division, it warned.

Besides, temporary waterlogging may occur in parts of Dhaka and Chattogram metropolitan areas, the BMD added.
