New Delhi, May 21 -- High humidity levels continued on Tuesday, keeping Delhi sweating for the second day in a row, as a heat index (HI) or "real feel" temperature of 49.6 degrees Celsius (degC) was recorded, according to India Meteorological Department (IMD) data. The maximum temperature was 41.8degC on the day, but humidity of 43-70% made for an uncomfortable afternoon. Gurugram, similarly, logged a maximum of 41.9degC. The power demand also surged to 7,401MW from 7,265MW a day earlier, marking the peak for the season for a second day in a row. Discoms BSES and Tata Power DDL said they were able to meet the demand. Meteorological experts said the intrusion of moisture from easterly winds, under the influence of a cyclonic circulation, is expected to keep the uncomfortable factor high this week, at least until Thursday, and possibly lead to spells of thunderstorms and gusty winds. "There are chances of isolated thunderstorm activity, scattered light rain and dust-raising winds gusting up to 50 km/hr till Thursday. Even after that, moisture content will remain high, meaning the maximum is not likely to rise too much," an IMD official said. Delhi's wet-bulb temperature, another indicator of thermal discomfort outside, was 29.14degC-up from 28.87degC a day earlier. The highest maximum temperature across the city was 42.5, recorded at the Palam and Pitampura weather stations. Delhi's minimum was, meanwhile, 28.7degC, while Gurugram was at 27.8degC on Tuesday. IMD forecasted the maximum to remain between 38degC and 40degC until Thursday, alongside high humidity. It forecasted a minimum of 26-29degC....
