Bihar Weather Report: As June begins, Bihar’s weather is shifting dramatically with a mix of cloudy skies, rainfall, and rising temperatures being reported across the state. On Wednesday, June 4, the India Meteorological Department (IMD) has forecast widespread rainfall and thunderstorms in several districts, accompanied by strong winds and lightning.
The IMD has issued an orange alert for 12 districts in the eastern part of Bihar, warning of moderate to heavy rainfall and gusty winds ranging from 50–60 kmph, along with thunderstorms and lightning. In total, 29 districts across North and South Bihar are under alert.
Cyclonic Circulation Behind the Weather Shift
According to the Regional Meteorological Centre in Patna, the unstable weather pattern is due to two upper-air cyclonic circulations:
- One is situated over Northwest Uttar Pradesh at an altitude of 1.5 km above mean sea level.
- The other lies over East Bihar at about 0.9 km above mean sea level.
These systems are enhancing moisture influx and instability in the atmosphere, leading to continuous rainfall activity in the eastern parts of the state.
Orange Alert: Eastern Bihar Braces for Stormy Weather
The following 12 districts in eastern Bihar have been placed under an orange alert for June 4: Purnia, Katihar, Kishanganj, Araria, Supaul, Madhepura, Saharsa, Bhagalpur, Khagaria, Munger, Jamui, and Banka.
These districts are expected to witness:
- Strong surface winds (50–60 kmph)
- Moderate to heavy rainfall
- Thunderstorms and lightning
The IMD has advised residents in these areas to stay indoors, avoid travel, and secure loose objects to prevent storm-related accidents.
Yellow Alert: Central and Western Bihar on Watch
A yellow alert has also been issued for 17 other districts, spanning central, northern, and southern Bihar. These include:
- North and Central Bihar:
East Champaran, West Champaran, Siwan, Saran, Gopalganj, Sitamarhi, Sheohar, Madhubani, Darbhanga, Muzaffarpur, Samastipur, and Vaishali - Southern Bihar:
Kaimur, Rohtas, Aurangabad, Gaya, and Nawada
These districts are likely to experience:
- Winds up to 30–40 kmph
- Light to moderate rainfall
- Thunderstorm activity and lightning in isolated areas
Morning Rain Activity and Regional Variations
On Wednesday morning, parts of North Bihar including Madhubani, Sitamarhi, Sheohar, and Supaul witnessed intermittent rainfall, aligning with the IMD’s earlier alerts.
On Tuesday (June 3), many districts in North Bihar, the western belt of South Bihar, and even Patna experienced light rain, though the intensity varied. Regions like Gaya, Aurangabad, Rohtas, and Kaimur reported higher rainfall accumulation.
Temperature Trends: Significant Drop in Many Regions
The rain and cloud cover led to a noticeable dip in temperatures across Bihar on Tuesday. Key figures include:
- Patna: 35.7°C (a drop of 4.1°C from the previous day)
- Aurangabad: Recorded the highest temperature at 38.4°C
- Madhubani: Noted the lowest maximum temperature at 31.01°C
- State Average: Approximately 34°C
This cooling trend has brought temporary relief from the intense summer heat, although the combination of humidity and intermittent sun may make conditions muggy and uncomfortable.
Forecast Ahead: What to Expect Next?
The IMD suggests that rain activity may persist in eastern and northeastern parts of Bihar over the next 48 hours due to prevailing cyclonic conditions. The weather is expected to remain unstable, with scattered thunderstorms across the state.
Safety Advisory from IMD
The public is advised to:
- Stay indoors during thunderstorms and heavy wind spells
- Avoid taking shelter under trees
- Unplug electrical appliances during lightning
- Monitor updates from local weather offices and emergency services
The fluctuating weather in Bihar is a direct outcome of seasonal atmospheric disturbances and cyclonic systems, bringing much-needed pre-monsoon rainfall but also raising concerns about lightning hazards and storm damage. With multiple alerts in place, citizens are urged to remain vigilant and follow weather advisories for safety.
