The weather conditions in Bihar continue to be impacted by consistent and widespread rainfall. Rivers across several parts of the state are now flowing above danger levels due to intense downpours. As per the Indian Meteorological Department (IMD), heavy rain is expected across the state for the next five days. However, weather experts believe the monsoon may start weakening gradually from Tuesday.

On Sunday, August 3, state officials were directed to remain on high alert in view of the rising water levels and continuous rainfall. For today, Monday, the IMD has issued a fresh rain alert for all districts in Bihar. Among them, five districts—particularly in the northwestern and northern regions—are likely to witness extremely heavy rainfall, along with thunderstorm activity and possible lightning strikes.

IMD Rain Alert for Motihari, Bettiah, Siwan, Sheohar, and Gopalganj

The IMD’s latest update indicates that East Champaran and West Champaran could experience intense rainfall throughout the day. Heavy rain is also predicted for Sheohar, Gopalganj, and Siwan districts. These regions are expected to see rainfall accompanied by strong winds ranging between 30 to 40 kilometers per hour. Due to this, the department has also issued alerts for thunderclaps and lightning, urging people to avoid outdoor activities during storm conditions.

All residents in these areas are advised to stay indoors when possible and follow safety instructions issued by local authorities and disaster management teams. Lightning strikes during monsoon rains are a known hazard in Bihar and have led to casualties in the past, making awareness and caution essential.

Consistent Rainfall Likely to Continue in Bihar for Five Days

The IMD has confirmed that the rainfall pattern over Bihar will likely remain consistent over the next five days. All districts are expected to experience light to moderate rain, with some pockets receiving heavier spells. From Tuesday onward, the monsoon may begin to weaken slightly, especially in southern and central districts. However, northern districts closer to the Nepal border may continue to see more intense rainfall due to prevailing weather systems.

The department has also asked district administrations to prepare for any emergency response in case of flooding, especially in low-lying areas and riverine villages. In rural and semi-urban areas, waterlogging has already started to affect daily life.

13 Districts Receive Heavy Rainfall; Madhubani Reports Highest

According to rainfall data from Sunday, almost every district in Bihar recorded rainfall, with many reporting significant downpours. Madhubani saw the highest rainfall, recording 171.2 millimeters, followed by Kishanganj at 152 millimeters. Siwan received 140.6 millimeters, while Purnia recorded 127.4 millimeters of rain.

Other districts also witnessed considerable rainfall. Begusarai recorded 102.4 millimeters, Supaul 111.6, and Muzaffarpur 91. Vaishali reported 90.8 millimeters, Samastipur 89.6, and Nalanda 87.6. In the Patna region, Danapur saw 78.4 millimeters of rainfall, while Fatuha recorded 72.2 millimeters. Rainfall in Punpun stood at 70, and Khusrupur recorded 67.2 millimeters. Saran received 77.8 millimeters, while Jehanabad registered 66.2 millimeters of rain. These rainfall figures reflect the widespread nature of the current monsoon pattern affecting the state.

Rain Leads to Drop in Temperatures Across the State

Due to the continuous rainfall, the mercury has dropped noticeably in several parts of Bihar. The highest temperature on Sunday was recorded in Bhagalpur at 33.1 degrees Celsius. On the other hand, the lowest maximum temperature was recorded in Ziradei, Siwan district, at 27.5 degrees Celsius.

In Patna, the rainfall helped bring the temperature down by nearly one degree. The city’s maximum temperature stood at 28.4 degrees Celsius on Sunday. Across the state, the average maximum temperature hovered close to 30 degrees Celsius, providing much-needed relief from the sweltering heat experienced in previous weeks.

However, despite the drop in temperature, humidity levels have remained high, leading to discomfort during the daytime. The weather department has not issued any heat-related warnings, but advises people to stay hydrated and avoid travel during peak rainfall hours.

Rivers Cross Danger Mark in Several Regions

Due to continuous rainfall in catchment areas, major rivers flowing through Bihar are now swelling rapidly. In several regions, river water has crossed the danger mark, posing a threat to nearby communities. People living along embankments and low-lying zones have been warned about possible flooding.

District administrations have been asked to keep flood shelters and relief materials ready. Rescue boats, drinking water, dry food, and medical supplies are being prepared in anticipation of potential displacement. In Motihari and surrounding flood-prone districts, the disaster response force has been put on alert.

In Patna, waterlogging has already disrupted normal traffic in many parts of the city, especially near railway stations and bus depots. The area outside Patna Junction railway station witnessed water accumulation on Sunday night, leading to inconvenience for commuters and travelers. Civic agencies are working to drain the water, but continued rainfall is slowing down the process.

Urban Areas Struggle with Drainage, Rural Areas Face Flood Risk

While cities like Patna, Muzaffarpur, and Bhagalpur are dealing with waterlogging due to poor drainage, rural regions are facing more severe challenges. Fields are waterlogged, and standing crops are at risk of damage. Farmers are concerned about the potential impact of the rain on upcoming harvests, especially in areas where paddy transplantation has just begun.

In some districts, schools have been instructed to remain closed as a precaution. Local officials are also monitoring embankments and small dams to ensure no breaches occur due to the pressure of increased water flow.

IMD Advises Caution and Continuous Monitoring

The IMD has advised the public to remain cautious over the coming days and to keep checking weather updates regularly. Local authorities are being urged to broadcast alerts on radio, television, and mobile networks. With the possibility of thunderstorm and lightning in several districts, residents are being encouraged to stay away from open fields, tall trees, and water bodies during storm activity.

Those who work in agriculture or transport should take special care during heavy rain spells. Schools, colleges, and administrative offices may issue localized advisories depending on the severity of rainfall in their respective areas.

As of now, rainfall in Bihar is expected to continue for five more days, with the possibility of slight monsoon weakening from Tuesday onward. The IMD’s alerts for East and West Champaran, Gopalganj, Sheohar, and Siwan districts should be taken seriously, as these areas are expected to face some of the heaviest rainfall in the state today.

With rivers flowing above danger levels and urban flooding already affecting several towns, both government agencies and citizens are being urged to stay alert and take necessary precautions. The weather may improve slightly after Tuesday, but until then, Bihar remains under a significant weather watch.
