Heatwave-like conditions are prevailing in major parts of Jharkhand with the mercury crossing the 40-degree Celsius mark, a weather official said on Friday. Since no significant synoptic condition is prevailing, the maximum temperature may rise by two to three degree Celsius from the existing temperature in the next 48 hours, he said. "Half of Jharkhand is reeling around 40 degree Celsius. The mercury may further rise by two to three degree Celsius in the next two days due to unrestricted flow of dry wind from Rajasthan and Central India," said Abhishek Anand, in-charge of Ranchi Meteorological Centre.
