Patna received 68 mm of rainfall Sunday. The capital is expected to remain cloudy Monday, although the possibility of continuous heavy rainfall is low. Light drizzle may occur in some areas.
Humidity and temperatures may rise once the rain subsides, while no significant change in temperature is expected over the coming week.
While rainfall continues in parts of the state, rising river levels have compounded the situation.
Heavy rainfall in Nepal and Uttarakhand has contributed to increased water levels in several rivers, with floodwaters now affecting 18 districts and approximately 6.65 lakh people.
The Ganga is flowing above the danger mark from Buxar to Bhagalpur.
The Punpun has risen 2.75 metres above the danger mark, with floodwaters reportedly overtopping or breaching protective embankments in the southern parts of Patna and entering residential areas.
Flooding has also disrupted transportation at several locations, with water affecting the Patna-Gaya railway section, Bihta Sarmera NH 78, and the Mokama National Highway.
The Son River has also caused flooding in riverside villages in the Bihta block, affecting around 20,000 people and submerging several roads.
According to the Meteorological Department, rainfall across Bihar is expected to remain uneven over the next few days, with localised cloud activity and light rain likely in different areas.
