The India Meteorological Department (IMD) has issued an urgent Bihar weather today update, warning residents of 15 districts about the onset of heavy rainfall and thunderstorms. As monsoon-related weather patterns intensify, the state is bracing for a mix of extreme climatic conditions, ranging from heavy downpours in certain regions to severe heat wave conditions in others.
According to the latest IMD forecast, while significant portions of Northern, Central, Eastern, and Southern India are experiencing active weather shifts, the impact is particularly notable across Bihar. On this Thursday, June 18, 2026, the state is facing a dichotomy of conditions. While some northern and eastern regions are expected to see relief in the form of rain, other parts of the state remain under a high-temperature advisory.
Rainfall and Storm Forecast Across Bihar Districts
The Bihar weather today alert covers a broad swath of the state, particularly the northern and northeastern districts. Citizens in Araria, Kishanganj, Purnia, Katihar, Supaul, Madhepura, Saharsa, Darbhanga, Madhubani, Sitamarhi, Muzaffarpur, East Champaran, West Champaran, Bhagalpur, and Banka have been advised to prepare for light to moderate rainfall. In addition to precipitation, the Patna Meteorological Department has warned of strong winds reaching speeds between 30 and 50 km per hour, particularly in the Seemanchal region.
These atmospheric disturbances bring a heightened risk of lightning strikes and potential localized flooding. Residents, especially those in rural areas or near infrastructure vulnerable to storms, are encouraged to stay updated with local advisories throughout the day to ensure their safety as the weather systems progress.
Heat Wave Warnings for Southern Bihar
While the northern districts manage rain and storm alerts, the southern and southwestern parts of Bihar are grappling with a different concern. An intense heat wave is predicted to impact areas including Gaya, Aurangabad, Rohtas, Kaimur, Bhojpur, and Buxar. Temperatures in these regions are forecasted to peak between 38 and 41 degrees Celsius.
This stark difference in Bihar weather today highlights the volatile nature of the current pre-monsoon and early-monsoon climate phase. Authorities have emphasized the importance of staying hydrated and minimizing direct sun exposure during peak hours for those residing in the high-temperature zones. The IMD continues to monitor the situation closely, providing regular updates to help local authorities and the public navigate these challenging meteorological events safely.
