The Met office predicted heatwave conditions will prevail over interior parts of the state while thundershowers and hailstorm may occur at some places in the coastal region.

Temperature in some parts of the coastal region came down two to three degrees today as there are possibilities of rain or thundershowers in these areas due to formation of a weak trough line stretching from north coastal Andhra Pradesh up to Odisha and Chhattisgarh, Director of Regional Meteorological Centre, Bhubaneswar, Sarat Chandra Sahu said.

Besides, there is also a possibility of Nor’wester at one or two places in the coastal districts, he said adding that the heatwave-like conditions would prevail in the state up to May 31.
