Bihar Rain Alert and Weekly Forecast
The Patna Meteorological Centre has issued an alert for rain, thunderstorms, and strong winds across multiple Bihar districts between October 29 and 31 as the northern impact of Cyclone Montha reaches the state. Moderate to heavy rainfall is expected in northern and northeastern districts, including Katihar, Kishanganj, Araria, Purnia, Supaul, and Madhepura, with wind gusts between 30-40 kmph accompanied by lightning.
On October 29, initial effects will be felt across western and central Bihar, spreading eastward by October 30-31, when the Seemanchal region is expected to experience the heaviest rainfall. While Bihar will not face direct cyclone landfall, moisture-laden winds from the system will cause heavy rainfall and a noticeable drop in temperature, signaling the onset of early winter chill.
The IMD has urged residents and local authorities to remain alert and advised caution in low-lying areas prone to waterlogging. Light rain and cloudy skies are likely after October 28, with a fall of two to four degrees Celsius in maximum temperatures expected after Chhath festivities conclude.
