Bihar is set to experience intensifying cold wave conditions from November 22-23 onwards, with the India Meteorological Department warning of minimum temperature declines of 2-4 degrees Celsius beginning November 24, signaling the onset of severe winter intensification. Currently, Bihar has benefited from temporary relief as westerly winds decelerate, though dense morning fog continues affecting visibility across northern and central districts. Patna recorded a maximum temperature of 28.7 degrees Celsius and a minimum of 17.7 degrees Celsius on November 21, while Purnia experienced visibility reduced to only 800 meters due to thick fog cover.
The meteorological department forecasts predominantly dry weather for the next 6-7 days with gentle westerly winds reaching approximately 25 kilometers per hour. However, Cyclone Senyar forming over the Bay of Bengal is expected to trigger light rainfall around November 23-24, potentially intensifying cold conditions when combined with the incoming weather system.
