The India Meteorological Department (IMD) has predicted above-normal rainfall across Bihar for the month of October. From October 3 to October 6, many districts in the state are expected to experience heavy rainfall. Citizens are advised to remain cautious and avoid unnecessary travel, especially during adverse weather conditions.
Forecast of Rainfall Across Bihar
As per the latest update, rainfall and thunderstorm activities are expected to continue throughout Bihar today, Friday, October 3. According to the weather department, several districts including Buxar, Bhojpur, Saran, Sitamarhi, Shivhar, Banka, Jamui, Jehanabad, Sheikhpura, Patna, Kaimur, Rohtas, Aurangabad, Arwal, and Jehanabad are likely to experience rainfall along with thunderstorms and strong winds. The IMD has issued a yellow alert for these areas, signaling potential weather hazards.
Additionally, districts like East Champaran, Gopalganj, Siwan, Rohtas, Aurangabad, and Nawada are placed under an orange alert due to the likelihood of heavy rainfall. Furthermore, regions such as Gaya, Kaimur, and West Champaran are under a red alert for extremely heavy rainfall. Over the past 24 hours, districts such as Patna, Buxar, Samastipur, and Purnia have already experienced rainfall, and the weather continues to be unpredictable with intermittent sunshine and rain.
Heavy Rainfall Expected in Bihar: Detailed Breakdown
The weather office has forecast that rainfall will persist across the state, particularly in the upcoming days. The return of the southwest monsoon is already underway. However, the low-pressure area in the Bay of Bengal, along with the associated trough line, is expected to keep rainfall chances high. This atmospheric setup could result in continuous light to moderate rainfall across Bihar, with some places experiencing heavy rainfall. The forecast indicates that October 3, 4, and 5 will see widespread rain throughout the state.
However, rainfall intensity is expected to reduce gradually between October 6 and 8, with some regions seeing a shift towards lighter showers. According to the meteorological department, the maximum temperature across most of Bihar will drop by 1 to 3 degrees over the next 48 hours due to the ongoing weather system.

The weather forecast for Bihar in the coming days indicates that the state will experience significant rainfall, with heavy to extremely heavy showers expected in many districts.
