Unseasonal rainfall has affected Bangladesh for several days, causing disruptions to daily life and raising concerns over the unusual weather pattern.
Meteorologist Mohammad Shahidul Islam told UNB that the continued rains are due to the monsoon axis still passing over the country.
“The rainfall may persist until mid-October,” he said.
The monsoon typically begins in June and retreats by mid-October. However, this year, the axis is still passing through Bangladesh, resulting in prolonged showers.
Islam explained that while rainfall this year is not significantly different from last year, the pattern varied by month: June experienced below-average rainfall, July saw above-average levels, and August and September had normal rainfall. Full data for the year is still pending.
The Bangladesh Meteorological Department has forecast total rainfall in October could range from 260 to 270 millimeters, surpassing the usual 167 millimeters.
A Met office bulletin also indicated that rain is expected across the country, including Dhaka, over the next five days starting Saturday.
The monsoon trough runs from Bihar and West Bengal to Assam and through the southern part of Bangladesh, with one of its associated troughs extending to the North Bay. The monsoon remains active in Bangladesh, while conditions in the North Bay are weaker to moderate.
According to the bulletin, light to moderate rain or thunder showers with gusty winds are likely in many areas of Chattogram and Sylhet divisions, a few places in Mymensingh, Dhaka, Khulna, and Barishal divisions, and one or two areas of Rangpur and Rajshahi divisions. Moderately heavy to heavy rain is expected in parts of Mymensingh, Dhaka, Khulna, Barishal, Chattogram, and Sylhet divisions.
Bangladesh’s monsoon season typically lasts from Asharh to Shraban, which corresponds to June through September in the Gregorian calendar.
