Summary:
“What we saw was convective rain — sudden, intense and for shorter period. The maximum and minimum temperatures are likely to be around 31 °C and 24°C respectively Rainfall generally varies even at street level, which we cannot measure. Apart from the weather stations in Nungambakkam and Meenambakkam, we have rain gauges at seven places but we collect readings only once a day in the morning,” an IMD official said.An official said IMD also got data from manual gauges maintained by commissionerate of revenue administration, but not all are in working condition.
