Heavy Rain Alert for Bhagalpur, Katihar, and Purnia; Strong Winds to Accompany Lightning
After enduring a grueling period of oppressive heatwaves and dry weather throughout June, the climatic conditions in Bihar are set to undergo a dramatic transformation. The Patna Meteorological Centre (IMD) issued a special weather bulletin predicting widespread rain, thunderstorms, and squally winds on Sunday (June 28, 2026).
The weather department has specifically flagged a Heavy Rainfall Alert for three major districts across Seemanchal and eastern Bihar—Bhagalpur, Katihar, and Purnia. Concurrently, a stern warning for severe thunderstorms and cloud-to-ground lightning strikes (vajrapath), accompanied by gusty winds clocking speeds of 30 to 40 km/h, has been issued for the north-western, south-central, and south-eastern regions of the state.
Heavy Rain in Three Districts: Immediate Relief from Sweltering Humidity
According to meteorologists, the activity of moisture-laden easterly winds flowing from the Bay of Bengal has intensified abruptly. This phenomenon has led to a thick accumulation of cloud cover over eastern Bihar.
Target Districts: Heavy downpours are anticipated in Bhagalpur, Katihar, and Purnia on Sunday. Torrential rains are expected in isolated pockets within these areas.
Temperature Drop: Over the last few days, temperatures in these districts hovered between 38°C and 40°C, leaving residents distressed by immense humidity. Following this spell of rain, maximum temperatures are projected to plummet by 3°C to 5°C, bringing immediate relief from the scorching summer heat.
Yellow Alert for Thunderstorms and Lightning: High Caution Appended
Alongside heavy rainfall, the IMD has signaled a Yellow Alert for heavy thunderclaps and hazardous lightning across a major portion of the state. Bihar's districts have been geographically grouped under three categories for this alert:
North-West Region (North-West Bihar)
Encompassing districts like West Champaran, East Champaran, Gopalganj, Siwan, and Saran, this pocket will witness a sudden atmospheric change by Sunday afternoon. Residents should anticipate localized dust storms and sporadic to moderate rainfall accompanied by lightning.
South-Central Region (South-Central Bihar)
This region includes the capital city of Patna, Gaya, Nalanda, Nawada, Sheikhpura, Begusarai, Jehanabad, and Lakhisarai. While these areas choked under extreme humidity on Saturday, Sunday will bring dense overcast skies, squally winds, and widespread thunder showers.
South-East Region (South-East Bihar)
For districts situated here—namely Munger, Khagaria, Jamui, and Banka—the weather bureau has asked the local administration and citizens to remain highly vigilant against potential casualty risks arising from lightning strikes.
Meteorological Analysis: Why Has the Weather Changed Suddenly?
According to the directors at the Patna Meteorological Centre, multiple synoptic weather systems are working in tandem from Northern to Eastern India:
Cyclonic Circulation: A strong cyclonic circulation is active over eastern Bihar and its adjoining skies at 0.9 kilometers above sea level. This system is effectively pulling massive amounts of moisture from the Bay of Bengal.
Trough Line Position: A seasonal weather trough line is extending all the way from Punjab, crossing Haryana and Uttar Pradesh, and terminating right over Bihar. This layout is pushing monsoon winds forward.
Monsoon Advancement: The Northern Limit of Monsoon (NLM) is currently advancing via Motihari. Conditions have turned entirely favorable for the monsoon to encapsulate the remaining parts of Bihar over the next 48 to 72 hours.
The Past 24 Hours: Records Broken in Sheikhpura Amid Heatwave Conditions
While Sunday brings a pleasant change, several parts of Bihar were baking under a severe heatwave as recently as Saturday afternoon.
| District | Maximum Temperature (Saturday) | Deviation from Normal | Status |
|---|---|---|---|
| Sheikhpura | 43.5°C | +7.1°C | Severe Heatwave |
| Kaimur (Bhabhua) | 42.8°C | +5.3°C | Heatwave |
| Buxar | 42.5°C | +4.9°C | Heatwave |
| Gaya | 41.9°C | +4.5°C | Heatwave |
| Dehri (Rohtas) | 42.2°C | +4.7°C | Heatwave |
The IMD noted that the incoming rain starting Sunday will rapidly collapse these high temperatures, neutralizing the severe heatwaves.
Upcoming 5-Day Weather Calendar: Widespread Rains Till July 2
The IMD has mapped out an extensive layout for rainfall across the state stretching up to July 2, 2026:
June 29 (Monday): The spatial distribution of rain will expand. An Orange Alert for extremely heavy downpours has been placed over Araria, Katihar, and Kishanganj.
June 30 (Tuesday): Districts bordering Patna, including Arwal, Bhojpur, Jehanabad, Nalanda, and Purnia, are likely to receive heavy downpours.
July 1 & 2: The monsoon will peak. Moderate to heavy rainfall will cascade across almost all 38 districts of North and South Bihar, providing a massive boost to farmers engaged in paddy cultivation.
Disaster Management Guidelines: Essential Safety Against Lightning
Lightning strikes cause dozens of casualties every year in Bihar during the monsoon season. In light of this, the Disaster Management Department has issued critical safety protocols, especially for farmers working in open fields:
Vital Safety Protocols:
Avoid Sheltering Under Trees: Never take shelter under tall or isolated trees during a thunderstorm. Trees act as natural lightning rods and carry the highest strike risk.
Evacuate Waterlogged Fields Immediately: Farmers working in waterlogged agricultural fields must immediately move to concrete, permanent buildings as soon as they hear the first rumblings of thunder.
Disconnect Electronic Appliances: Avoid using electronic appliances like TVs, refrigerators, or keeping mobile phones on charge during severe lightning to avoid electrical surges.
Stay Away from Metallic Structures: Avoid standing near iron poles, barbed-wire fences, or keeping close contact with bicycles and motorcycles.
Cumulatively, Sunday marks a major, welcoming turning point for Bihar’s climate. While residents of Bhagalpur, Purnia, and Katihar get to enjoy torrential downpours, the state administration has advised everyone to exercise caution against lightning hazards. From an agricultural standpoint, this rain is nothing short of an elixir for the region’s agricultural prospects.
