RANCHI: The scorching summer heat has returned to the state as the advance of southwest monsoon seems unlikely this week as well.With mercury levels steadily rising across the state over the past 72 hours, the Ranchi office of the India Meteorological Department (IMD) on Monday issued a heat wave alert for isolated parts of the state in the coming next two days."Isolated parts of Jharkhand experienced heat wave conditions in the past 24 hours. This similar situation is likely to prevail in isolated parts as well, namely northern districts, on Tuesday," IMD Ranchi said in a statement which was issued in the evening."However, most parts of the state will have partly overcast conditions from Wednesday onwards. Some places may get light to medium showers," it said.With the southwest monsoon trough falling weak, its onset over the state has already been delayed for over a week now. This has led to teh rising daytime temperatures across the state. The afternoon temperature in Jamshedpur stood at 42.1° Celsius on Monday, six notches above its normal temperature.Daltonganj recorded 42° Celsius, five notches above normal daytime average. The daytime temperature in Giridih was 7 notches above its normal of 33° Celsius.

The maximum temperature was recorded at 39° Celsius in Ranchi on Monday afternoon, over six notches above its normal average during this time.Scientists at IMD Ranchi hinted that the southwest monsoon's onset over the state was unlikely for another week."It is unlikely to advance into the state in the next six due to prevalence of weak monsoon pattern over the area," a weatherman said. The normal onset of monsoon in Jharkhand was last week - between June 10 and June 12.Monsoon arrived a week behind its schedule in 2017. However, it made up for the delay towars the end of its closing stages, pushing the cumulative rain in Jharkhand in the monsoon months (June 1 to September 30) to recorded at 978.8mm, 10% less than the normal average of 1,092mm.The IMD in its recent long-range-forecast had predicted that northeast states will receive 95% of its average monsoon rains this year. "Central states are expected to receive 96% rains as per our LRF. With Jharkhand geographically sitting in between central and northeast states, it is expected to receive 95% rains this year," a senior weather scientist at Ranchi IMD said.
