Overview: What’s Happening and Why It Matters
With monsoon intensifying across eastern India, Bihar’s northern belt is facing widespread rainfall, causing disruptions in daily life. According to the India Meteorological Department (IMD), heavy to very heavy rain is likely in many areas, especially in North Bihar. As a precaution, the IMD has issued an Orange Alert for 19 districts, signaling a potentially dangerous weather situation through Sunday and Monday.
The warning comes at a time when rivers like the Ganga and Son are already swelling, threatening low-lying areas. Strong monsoon currents and a passing monsoon trough over Muzaffarpur have caused significant atmospheric pressure drops, leading to a dense cloud cover and continued rainfall.
Rainfall and Weather Alert Summary (Region-wise)
| Alert Level | Districts Affected | IMD Forecast |
|---|---|---|
| Orange Alert | Muzaffarpur, Sitamarhi, Madhubani, Darbhanga, Champaran, etc. | Heavy rainfall, lightning, strong winds |
| Yellow Alert | Araria, Supaul, Kishanganj, Purnia | Moderate rain, isolated thunderstorms |
Practical Impact and Observations
-
Rainfall Intensity: Light rain has continued in Patna since early Sunday. However, the rainfall isn’t intense enough yet to cool down surface temperatures.
-
Temperature Trends: On Saturday, Patna recorded a rise of 0.8°C in max temperature and 1.7°C in minimum, pushing humidity to 56%, leading to severe discomfort among residents.
-
Atmospheric Conditions: Low atmospheric pressure and a trough passing over Muzaffarpur are increasing the cloud density, suggesting heavy downpours and stormy conditions.
-
Wind Speed Forecast: Winds may blow at 30–40 km/h, raising the risk of localized damage or tree fall in open areas.
Comparison to Previous Days
Unlike the previous two days when rainfall was nearly absent across Bihar, today’s conditions mark a sharp return of active monsoon behavior. The temperature had surged due to dry skies, but current patterns suggest a cooling trend will follow once sustained rainfall begins.
