Scattered rain, thunderstorms likely until Tuesday as nor’wester season kicks in

Scattered rain, gusty winds, and thunderstorms are likely to occur across various parts of Bangladesh until Tuesday, according to the Bangladesh Meteorological Department (BMD).

Meteorologist Omar Faruq told bdnews24.com on Friday that the country has entered the season of nor’wester, which, in other words, is a season of unpredictable localised storms.

"Scattered rain is likely almost every day through the end of March," Faruq said. "Thunderstorms and gusty winds are also expected in places."

The forecaster's 24-hour Friday bulletin issued in the morning said a seasonal low-pressure system is positioned over the south Bay of Bengal, with an extension reaching West Bengal and surrounding areas.

On Friday, the Met Office said in an extended outlook, rain or thundershowers with gusty winds are expected in many parts of the Rangpur, Rajshahi, Mymensingh, Dhaka, and Sylhet divisions. 

A few areas in Khulna, Barishal, and Chattogram may also see light precipitation, according to the bulletin.

On Saturday, scattered rain is likely in the Rangpur, Mymensingh, and Sylhet divisions.

Rainfall is expected to expand, potentially covering parts of the Chattogram Division along with the northern and central regions from Monday, the BMD said.

Over the last 24 hours, ending at 6am on Friday, the country's highest temperature was recorded in Bandarban at 33.8°C, while the lowest was 20°C in Nilphamari’s Dimla. The highest rainfall during this period was 18mm, recorded in Dinajpur.

While day and night temperatures are expected to rise slightly on Saturday, the BMD predicts a minor cooling trend on Sunday and Monday. 

Temperatures, however, are expected to climb significantly after Tuesday for the following five days.
