In Met parlance, a heat wave condition is declared when the maximum temperature climbs five notches above the average normal. Kotal, director of Ranchi Met centre, said a “moderate heat wave” was prevailing in many places across the state. But, Ranchi Met issued an alert of thunderstorm, accompanied with gusty winds of 30-40 kmph speed and lightning at a few isolated pockets on May 12 and 13. On Thursday, towns such as Daltonganj, Jamshedpur and Ranchi reeled under oppressive heat with the mercury crossing the 40°C mark. Capital Ranchi recorded 41°C on Thursday, higher than 40.2°C the day before.
