KKN Gurugram Desk | Bihar is likely to experience significant weather fluctuations over the next 24 hours, accordng to the India Meteorological Department (IMD). The shift comes after a prolonged spell of intense heat in April and early May. Cloud cover, thunderstorm activity, and the possibility of heavy rainfall in specific districts are all forecasted.

A yellow alert has been issued for three districts—Katihar, Kishanganj, and Purnea, with warnings of thunderstorms, lightning, and localized heavy showers.

Monsoon Activity: How Moisture from the Bay of Bengal is Influencing Bihar’s Weather

The recent atmospheric instability is being attributed to a moisture-laden easterly wind blowing in from the Bay of Bengal, coupled with a trough line formation across the region. This has led to a change in the weather system, triggering thundercloud development and the likelihood of moderate to heavy precipitation.

According to IMD-Patna, a mix of high humidity and elevated temperatures is creating the perfect environment for stormy conditions, especially in northern and northeastern districts.

Cloud Cover Across Bihar: Relief from Rising Temperatures

Major parts of Bihar, including Patna, are expected to remain under a thick cloud cover throughout the day. This brings temporary relief from the scorching summer heat, which has gripped the region for several weeks.

• Patna’s maximum temperature on Tuesday was recorded at 36.7°C.

• Dehri-on-Sone remained the hottest spot in the state with 41.0°C.

• The highest rainfall was reported from Araria’s Jokihat block, which received 87.8 mm of rain.

IMD Forecast for Next 24 Hours: Thunderstorms, Lightning Likely

The Meteorological Centre in Patna has issued a detailed forecast, suggesting that thunderstorms and lightning will affect isolated parts of Bihar over the next day.

Districts to remain alert:

• Katihar

• Kishanganj

• Purnea

All three districts are under a yellow alert due to the high likelihood of heavy downpours, accompanied by thunder and wind speeds ranging between 30–40 km/h.

Rainfall Data: Where It Rained the Most

As per the latest weather monitoring data, several districts in Bihar have already started receiving rainfall. The northeastern belt has been particularly affected.

The eastern and northern regions are expected to bear the brunt of the weather system, while central Bihar will witness cloudy skies and scattered rainfall.

Relief from Heatwave: But Humidity Persists

While the rain is bringing a much-needed break from the ongoing heatwave, residents should brace themselves for an increase in humidity levels, particularly due to the easterly winds. The combination of high minimum temperatures and moisture content in the air is likely to make the atmosphere muggy and uncomfortable in parts.

Impact on Daily Life: Advisory for Residents

The state disaster management authorities have issued precautionary advisories urging citizens to avoid open areas during thunderstorms. The possibility of lightning strikes and wind damage is non-negligible.

Safety Tips for Residents:

• Stay indoors during thunderstorms.

• Avoid using electrical appliances during lightning activity.

• Farmers are advised to avoid working in the fields during storm warnings.

• Keep mobile devices charged in case of power disruptions.

Agricultural Outlook: Rain Beneficial for Some, Risky for Others

The unexpected rainfall could be favorable for certain summer crops, particularly in rain-fed areas. However, for regions where crops are at the maturity or harvest stage, heavy showers may cause waterlogging or crop damage.

Agricultural experts suggest that farmers keep an eye on updates and take preventive measures to secure their produce.

Looking Ahead: What Does the IMD Say for the Coming Days?

IMD has indicated that unsettled weather conditions may continue in Bihar until the end of this week. Cloud cover, scattered rainfall, and periodic storms are expected to occur in intervals.

Forecast Summary:

• Rain and thunderstorms for the next 48–72 hours in north and northeast Bihar.

• Continued humidity due to easterly winds.

• No severe heatwave expected during this period.

District-wise Weather Alert Summary

Expert Opinion: What Meteorologists Are Saying

Meteorologists have emphasized that the current weather pattern is seasonal but slightly early in terms of storm activity. The early buildup of cloud systems is due to a quicker shift in atmospheric pressure zones.

Dr. Anil Kumar, a senior climatologist, stated:

“This is a classic pre-monsoon weather pattern influenced by Bay of Bengal moisture and inland trough activity. Residents should stay updated and prepared, especially in vulnerable districts.”

The current weather conditions in Bihar highlight the unpredictable nature of pre-monsoon systems. While rainfall is offering respite from the heat, the risk of thunderstorms, lightning, and heavy showers remains. Authorities and residents alike must stay alert and follow advisories to ensure safety and minimal disruption.
