Heavy to very heavy rain likely for next five days

Bangladesh is expected to experience widespread rainfall over the next five days as an active monsoon continues to influence weather conditions across the country, the Bangladesh Meteorological Department (BMD) said on Monday.

In its 120-hour forecast issued at 6:00 pm on July 13, the BMD warned of moderate to very heavy rainfall in different parts of the country, with thunderstorms and gusty winds also likely in many areas.

According to the weather office, the monsoon trough extends through Punjab, Haryana, Uttar Pradesh, Bihar, West Bengal and central Bangladesh to Assam, with another extension reaching the northern Bay of Bengal. The monsoon remains active over Bangladesh and is in a moderate state over the northern Bay.

For the first 24 hours from Monday evening, most areas of Rangpur, Rajshahi, Mymensingh, Dhaka, Khulna, Barishal, Chattogram and Sylhet divisions are expected to receive light to moderate rain or thundershowers accompanied by temporary gusty winds. Some places may experience moderate to very heavy rainfall. Day temperatures may fall slightly, while night temperatures are expected to remain nearly unchanged.

During the following 24 hours from Tuesday evening, rain or thunderstorms are likely in many areas of Rangpur, Rajshahi, Mymensingh and Sylhet divisions, and at a few places in Dhaka, Khulna, Barishal and Chattogram divisions. Heavy to very heavy rainfall is also possible in isolated locations. Both day and night temperatures may rise slightly.

The weather pattern is expected to remain largely unchanged on the third day, with rain or thundershowers forecast for many areas of Rangpur, Rajshahi, Mymensingh, Chattogram and Sylhet divisions, and a few places in Dhaka, Khulna and Barishal divisions. Heavy to very heavy rainfall may occur in some areas, while temperatures are likely to increase slightly.

On the fourth day, rainfall is expected to become more widespread, with most places in Khulna, Barishal, Chattogram and Sylhet divisions, and many areas of Rangpur, Rajshahi, Mymensingh and Dhaka divisions likely to receive rain or thundershowers. Some locations in the southern and northeastern divisions may experience moderate to very heavy rainfall. Day and night temperatures may decline slightly.

The forecast indicates that the wet weather will continue into the fifth day. Most areas of Dhaka, Khulna, Barishal, Chattogram and Sylhet divisions, along with many places in Rangpur, Rajshahi and Mymensingh divisions, are likely to receive rain or thunderstorms. Moderate to very heavy rainfall is also expected at isolated places in Dhaka, Khulna, Barishal, Chattogram and Sylhet divisions.
