A new low-pressure system has formed over the South Andaman Sea and adjoining areas following Cyclone Arnab, which recently struck India’s Andhra Pradesh, the Bangladesh Meteorological Department (BMD) said on Friday.
According to the department’s five-day weather forecast, the remnants of Cyclone Arnab have weakened into a well-marked low-pressure area over Chhattisgarh and adjoining regions.
The new low-pressure system over the South Andaman Sea is likely to move west-northwestwards and intensify further, the forecast said.
The BMD also predicted rain or thundershowers accompanied by temporary gusty winds in many places across Rangpur, Rajshahi and Khulna divisions until 9am on Saturday. A few places in Mymensingh, Dhaka, Barishal, Chattogram and Sylhet divisions may also experience rainfall.
Day and night temperatures may fall slightly across the country during the period.
Rain is likely to continue in different divisions over the following four days, while temperatures may decline further over the next five days.
