Rain To Continue In Patna And Nearby Districts
The IMD has forecast continued monsoon activity over Patna and neighbouring districts.
Light to moderate rainfall is expected across Patna, Nalanda, Jehanabad, Nawada, Gaya, Lakhisarai, Sheikhpura, Begusarai and Samastipur, with heavy rain likely at isolated places.
In south-western Bihar, including Rohtas, Kaimur (Bhabua), Bhojpur, Buxar, Arwal and Aurangabad, isolated thunderstorms accompanied by rain are also expected.
Strong Winds Changed Weather In Patna
