⚠️ Bihar Braces for Thunderstorms and Rain Between April 7–11, 2025

The weather in Bihar is undergoing rapid fluctuations as Western Disturbance systems move across Northern India, affecting large parts of the state. The India Meteorological Department (IMD) has issued a Yellow Alert for several districts in Bihar for the period from April 7 to April 11, 2025.

As per the Patna Meteorological Centre, residents should prepare for light rainfall, thunderstorm activity, lightning, and wind speeds ranging between 40–50 km/h.

???? Key Weather Highlights for Bihar (April 6–11, 2025)

• ????️ April 7–11: Thunderstorms, lightning, and rain likely in northern and eastern districts

????️ 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.

????️ Districts on Alert: Likely to Experience Rain and Storms

The following districts are under Yellow Alert for possible thunderstorm activity, lightning, strong winds, and localized rainfall:

Northern Bihar:

• Sitamarhi

• Madhubani

• Muzaffarpur

• Darbhanga

• Vaishali

• Shivhar

• Samastipur

Northeastern Bihar:

• Supaul

• Araria

• Kishanganj

• Madhubani

• Saharsa

• Madhepura

• Purnia

• Katihar

Southeastern Bihar:

• Bhagalpur

• Banka

• Jamui

These regions may also witness sudden temperature drops and local hail formation during thunderstorm activity.

????️ Heatwave Update: Mercury on the Rise Before the Rain

Before the anticipated weather shift, Bihar is witnessing dry heat and rising daytime temperatures. Here’s a brief of maximum temperatures recorded on Saturday, April 5, 2025:

As per IMD, daytime temperatures may rise further by 1–3°C in the next 48 hours, especially in central and southern Bihar.

⚠️ 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.
