People in Chennai cant forget the record rains we got in August 2011, where 120 year records were shattered by a distance. Particularly the 156 mm rainfall on 24th August, 2011 when thunderstorms formed in the evening kept on coming like a bubble till early morning.
Yesterdays rainfall is also similar, first storms were spotted in radar in the evening and the storms kept on coming like a bubble till early morning. Chennai got 76 mm from this TS, thus crossing 800 mm for the year before the start of NE monsoon. Recently, Chennai's annual rainfall is increased from 1220 mm to 1400 mm by IMD and the last 10 year average works out 1460 mm with 2560 mm received in 2005 being the highest.
We have received 836 mm till today morning, considering the rainfall and daily thunderstorms coming close to Chennai, we have to rethink whether Chennai really falls under rain shadow region. More studies have to initiated by IMD to study this daily phenomenon of Thunderstorms coming above and below belts of Chennai (from Pulicat to Pondicherry). The Radar at Chennai is also the best in India, because of less interference from height restrictions IMD has put in place for Construction of High Rise buildings.
