Rain and Thundershowers Forecast Across Bangladesh’s Eight Divisions

Bdbusinessdaily.com – Much of Bangladesh is expected to experience rain or thundershowers during the 24-hour period beginning at 9am on Saturday, 12 September, as monsoon conditions remain active across the country.

The Bangladesh Meteorological Department has indicated that rainfall may affect all eight divisions, including Dhaka. Temporary gusty winds could accompany some of the showers, while isolated locations may see moderate to heavy rain.

Areas Most Likely to Receive Rain

Rainfall is expected at many locations in Rangpur, Mymensingh, Khulna and Sylhet divisions. Rajshahi, Dhaka, Barishal and Chattogram divisions may also receive rain or thundershowers, though the forecast places the likelihood at fewer locations in those regions.

“Light to moderate rain or thunder showers accompanied by temporary gusty wind is likely to occur at many places over Rangpur, Mymensingh, Khulna and Sylhet divisions and at a few places over Rajshahi, Dhaka, Barishal and Chattogram divisions with moderately heavy to heavy falls at places over the country.”

The outlook means weather conditions may vary significantly from one area to another. Some communities could receive brief showers, while others may experience stronger rainfall over a shorter period. Gusty winds during thunderstorms can also make outdoor travel and work more difficult, particularly when rain begins suddenly.

Temperatures May Ease Slightly

Both daytime and nighttime temperatures may decline slightly across Bangladesh during the forecast period. Cloud cover and rainfall often reduce daytime heat, although humidity can remain noticeable during the monsoon season.

A small fall in temperature does not necessarily mean dry or settled weather. Rain-bearing clouds, changing wind conditions and periods of sunshine can produce shifting conditions throughout the day. Residents planning outdoor activities may find it useful to remain alert for local changes in the sky and wind.

Low-Pressure System and Monsoon Pattern

The weather pattern is being influenced by a low-pressure area that was previously over the coastal areas of Odisha and Andhra Pradesh. The system has moved and is now located over South Chhattisgarh and nearby areas.

The monsoon trough extends through Rajasthan, Uttar Pradesh, the centre of the low-pressure system, Bihar, Gangetic West Bengal and Assam. It then crosses the southern part of Bangladesh. This broad atmospheric pattern is helping sustain rain-producing conditions over the country.

Monsoon activity remains fairly active over Bangladesh, while conditions over the North Bay are described as moderate. During an active monsoon phase, moisture-rich air and regional weather systems can support repeated rain bands and thunderstorms in different parts of the country.

What the Forecast Means for Daily Plans

The forecast covers the entire country, but rainfall is not expected to occur continuously everywhere. Conditions may change quickly, especially in places where thundershowers develop. A clear morning can give way to clouds, wind and rain later in the day.

People travelling by road, working outdoors or making plans involving open spaces may need to allow extra time for weather-related disruption. Sudden downpours can reduce visibility, and temporary gusty winds may create uncomfortable conditions for pedestrians, cyclists and those using smaller vehicles.

Heavy rain in isolated areas can also affect routine movement, particularly where drainage takes time to clear accumulated water. The forecast does not indicate that every location will receive heavy rainfall, but residents in rain-prone areas may wish to keep essential travel and outdoor arrangements flexible.

Rainfall Remains a Seasonal Feature

Rain and thunderstorms are a familiar part of Bangladesh’s monsoon weather cycle. The country’s position near the Bay of Bengal, combined with regional low-pressure systems and monsoon circulation, regularly brings changing rain patterns during this period.

The current outlook reflects that wider seasonal setup: active monsoon conditions over Bangladesh, a moderate state over the North Bay, and a trough stretching across several parts of South Asia. Together, these features support the possibility of showers across all divisions.

While the expected slight temperature drop may bring some relief from daytime warmth, the accompanying rain and gusty winds remain the main features of the forecast. People are advised to remain mindful of changing local conditions through the day and evening as the wet-weather pattern continues.
