Sporadic thunderstorm activity, especially in coastal Odisha, may occur till June 26, but monsoon rain is likely to pick up momentum thereafter due to formation of a cyclonic circulation over north Bay of Bengal, the Centre for Environment and Climate (CEC) at the SOA University said on Tuesday.
This cyclonic circulation may turn into a low pressure area within 48 hours from June 27, CEC director Dr SC Sahu said. Heat wave conditions, however, might continue over coastal and adjoining districts up to June 21 with a decline in temperature as compared to last three days, he said, adding that the mercury may hover between 36 and 38 degrees Celsius. The aerosol concentration, as per satellite data, had decreased in eastern India indicating the probability of fall in temperature and isolated thunderstorm activity over coastal Odisha and adjoining districts. But rainfall might not be widespread and heavy due to strong convection over Bangladesh and adjoining Myanmar which might cause subduction of air over the Odisha region to support decrease of rainfall, Dr Sahu said.
