🌦️ Western Disturbance to Influence Bihar’s Weather
According to the IMD, a cyclonic circulation system associated with a Western Disturbance is currently positioned over Northeast Assam and nearby regions. By April 8, it is expected to intensify and shift towards the Western Himalayan region, triggering instability in the Gangetic plains, especially in Bihar.
This weather system is likely to bring temporary relief from rising temperatures, but also increases the risk of hailstorms, property damage, and disruption in power supply due to lightning.

⚠️ What Is a Yellow Alert?
A Yellow Alert is issued by the IMD to indicate potential severe weather conditions. It is a precautionary alert asking citizens to “Be Aware” and take safety measures. While not as serious as Orange or Red Alerts, it signals the need for preparedness especially in rural and exposed regions.
🛡️ IMD’s Public Advisory
-
✅ Avoid travel during peak thunderstorm hours (2 PM–8 PM)
-
✅ Stay indoors during lightning activity
-
✅ Keep electronic devices unplugged during storms
-
✅ Farmers should delay irrigation and protect standing crops
-
✅ Urban residents should watch for tree falls, traffic delays, and waterlogging
🧩 Climate Insight: What’s Driving the Shift?
The current weather pattern is influenced by a combination of:
-
🌍 Western Disturbance affecting the Himalayan belt
-
🌀 Cyclonic circulation over Northeast India
-
🌬️ Dry winds from the west causing heat buildup
-
🌧️ Moisture feed from the Bay of Bengal aiding thunderstorm formation
This confluence has created a transitional climate phase, typical for North India during pre-monsoon months.
🔄 What to Expect After April 11?
Meteorologists expect the weather to stabilize post-April 11, but with a gradual build-up of humidity. As we head deeper into April, heatwave conditions may return, particularly in southern Bihar and adjoining Jharkhand.
Farmers, students preparing for exams, and outdoor workers are advised to follow daily weather bulletins closely.
The week ahead poses a mix of relief and risk for the people of Bihar. While the thunderstorms could cool the region temporarily, the associated lightning, gusty winds, and hail present dangers that shouldn’t be ignored.
