The Patna office of the meteorological department has officially rolled out a yellow alert for Bihar concerning incoming severe weather this Wednesday, July 22. Forecasters are urging residents to prepare for a volatile mix of atmospheric conditions, including hazardous lightning strikes and intense thunderstorms. These turbulent weather patterns are primarily expected to sweep through the southwestern, south-central, and northeastern territories of the state.
Heavy Rain Expected In Seemanchal
Accompanying the electrical storms, strong surface winds blowing at speeds between 30 and 40 kilometers per hour will likely create additional challenges for locals. Officials emphasize that the Seemanchal belt is positioned to endure the most significant impact from this incoming climatic shift.
Within this vulnerable zone, the districts of Purnia, Kishanganj, Banka, and Araria have been placed under a strong probability for substantial rainfall. The meteorological data categorizes the precipitation in these specific administrative areas as fairly widespread. Meanwhile, communities residing in other parts of the state should anticipate a much lighter, scattered distribution of rain over the course of the day.
Temperature Fluctuations
On the temperature front, the overall climate will remain humid and warm throughout Wednesday. Statewide maximum thermal readings are projected to hover anywhere from 30 to 32 degrees Celsius. During the nighttime, minimum temperatures will generally settle between 24 and 28 degrees Celsius.
However, a distinct microclimate effect will be felt in the northeastern districts. Regions encompassing Saharsa, Madhepura, Katihar, Supaul, Kishanganj, Araria, and Purnia are forecasted to experience slightly warmer nights, with their lowest temperatures resting in the 26 to 28 degrees Celsius bracket. Looking slightly further ahead, weather scientists indicate that daytime heat could intensify, with maximum temperatures potentially jumping by 2 to 4 degrees Celsius over the upcoming 48 hours. Nighttime conditions are expected to remain relatively stable for the next five days.
Past Rainfall and System Shifts
Analyzing the immediate past, the previous 24 hours brought isolated heavy downpours to several districts, notably Siwan, Gaya, Supaul, Buxar, and Katihar. The rest of Bihar mostly witnessed gentle to moderate showers. During this period, the highest volume of precipitation was logged in Manihari, which received an impressive 109 millimeters of rain, closely followed by Dumraon with 71.4 millimeters. Temperature extremes recorded on Monday highlighted Motihari in East Champaran as the hottest location at 32.4 degrees Celsius, while Gayaji offered the coolest conditions at 24.4 degrees Celsius.
Meteorologists attribute these unstable conditions to several overlapping atmospheric systems. The primary driver is the monsoon trough, currently tracing a path through Sri Ganganagar, Rohtak, Hamirpur, Sidhi, Ranchi, and Digha. This massive weather band is actively advancing in a southeasterly direction toward the northwestern Bay of Bengal.
Additionally, a cyclonic circulation previously hovering over southern Uttar Pradesh has recently migrated toward northeastern Madhya Pradesh and its adjacent zones. In contrast, another upper air cyclonic formation located above northern Jharkhand and bordering areas of Bihar has lost its intensity. The combined interaction of these shifting systems will continue to fuel localized rain and thunder activities across the state.
Critical Safety Guidelines
In light of these volatile forecasts, authorities have issued strict safety guidelines for the public. Residents living in districts marked by thunderstorm and lightning warnings must remain highly vigilant and continuously track the latest weather bulletins. A specific appeal has been directed at farmers working in exposed agricultural fields and individuals occupying open outdoor spaces. They are strongly advised to immediately retreat to secure, covered shelters at the very first sign of lightning or thunder to prevent tragic accidents.
