The India Meteorological Department (IMD) on Tuesday, 7 July issued a Yellow alert for the entire state of Bihar, warning of widespread rainfall, thunderstorms, gusty winds, and lightning. Dark clouds blanketed several parts of the state, including the capital Patna, as rain and strong winds brought relief from the prevailing heat. The IMD has cautioned residents to remain vigilant, particularly during thunderstorms, given the heightened risk of lightning strikes.
Districts Under Heaviest Threat
The IMD has flagged Kishanganj, Katihar, Bhagalpur, Banka, and West Champaran as likely to receive heavy rainfall. Isolated areas across the state also face the possibility of hailstorms. Over the past 24 hours, rainfall was recorded in Patna, Rohtas, Buxar, and Aurangabad, while Patna, Banka, Nalanda, and Jamui witnessed showers accompanied by strong winds on Monday afternoon.
Temperature Drop Across the State
The ongoing rainfall has triggered a drop of approximately 1–3 degrees Celsius in daytime temperatures across many parts of Bihar. Wet weather is forecast to continue over the state for the next five days, according to the IMD.
Alert Levels Day by Day
A Yellow alert remains in effect for the entire state on Wednesday, 9 July. Additionally, an Orange alert has been issued for Sheohar, Sitamarhi, Madhubani, Araria, Supaul, Muzaffarpur, Kishanganj, Vaishali, Darbhanga, Samastipur, Saharsa, Katihar, Madhepura, and Purnea on that day, with remaining districts under a Yellow alert.
On 10 July, an Orange alert covers East Champaran, West Champaran, Sitamarhi, Sheohar, Madhubani, Gopalganj, Siwan, Saran, Darbhanga, Vaishali, Muzaffarpur, and Samastipur, while the rest of the state remains on a Yellow alert. By 11 July, a Yellow alert will continue statewide, with cloudy skies, intermittent rainfall, and thunderstorms expected across many areas.
What Is Driving the Wet Spell
Meteorologists attribute the current rain activity to an active monsoon trough passing through eastern India. A low-pressure area over the northwestern Bay of Bengal is simultaneously supplying abundant moisture to the region. Together, these systems are expected to sustain widespread rainfall, thunderstorms, and lightning across Bihar over the coming days.
IMD Safety Advisory
The IMD has advised residents to avoid open fields, trees, and water bodies during thunderstorms, monitor official weather updates regularly, and take necessary precautions in areas vulnerable to heavy rain and lightning. This comes amid Bihar's historically high vulnerability to monsoon-season lightning fatalities — a recurring concern for state disaster management authorities each year.
Point of View
Orange across northern districts — reflects a familiar seasonal pattern, but the framing of it as routine weather news risks obscuring a genuine public safety crisis. Lightning strikes kill hundreds of people in Bihar every monsoon season, consistently ranking the state among India's most fatality-prone. The IMD's advisory is technically sound, but the gap between issuing alerts and translating them into last-mile community warnings — particularly in rural, low-connectivity districts like Sheohar and Madhubani — remains the real accountability question. State disaster management authorities need to be asked not just what the forecast says, but how many villages have actually been reached.
