Patna: The India Meteorological Department (IMD) has issued a yellow alert for rainfall across 23 districts of Bihar on Tuesday, warning of strong winds and heavy showers over the next 48 hours. The department also predicted a drop of 2 to 3 degrees Celsius in night temperatures, with relief from rain likely only after mid-October.
According to meteorologists, a low-pressure area has developed over the Bay of Bengal and adjoining regions, drawing moisture-laden winds from southeast and central India, which have activated a trough over Bihar. The combined effect of these systems has led to widespread cloud cover and persistent rainfall across many districts.
Experts added that while the increased humidity may cause discomfort, temperatures are expected to fall slightly if the rain continues. The impact of this weather system will likely persist for the next 24 to 48 hours.
Flood Threat Returns as Nepal Rains Intensify
Heavy rainfall in Nepal has worsened the flood situation in northern Bihar. Rivers like the Kosi and its tributaries are in spate, leading to waterlogging and breaches in several areas.
In Supaul, six blocks have been affected, with around 5,000 houses inundated. In Madhubani, nearly one lakh people have been impacted by rising water levels. Flooding from the Sarsawa River in Nepal has caused a flood-like situation in Raxaul and nearby areas, including Ramgarhwa, Sugauli, Semra, and Motihari.
In Araria, floodwater entered over 1,000 houses following a dam breach, while in Kishanganj, river water is flowing over the Chandra Village bridge, disrupting road connectivity between Tedhagachh and Bahadurganj. Erosion has also been reported in the low-lying areas of Vaishali, and floodwater has entered the Indian Embassy bungalow in Raxaul.
Monsoon Still Active in Patna
In the state capital Patna, monsoon activity remains strong. The IMD has forecast cloudy skies with light to moderate rain. The maximum temperature may fall below 30 degrees Celsius, while humidity levels are expected to remain between 70 and 80 percent, bringing a slight chill in the morning and evening hours.
Meteorologists say that with continuous rainfall in Bihar and neighboring Nepal, the risk of further flooding in north Bihar districts cannot be ruled out.
