Records breaking Heavy rains in Chennai in August 2011

Heavy rains lashed the city late in the evening on Wednesday and went on to mid night. The lack of usable storm water drains was felt keenly, as many places were flooded. As much as two to three feet of water was seen on most of the roads. The intensity of the rain sometimes was more than 100 mm/hr.

Records Broken

The all-time record for 24hrs rainfall in August till yesterday for Chennai was 100.3 mm recorded on 20.08.2008. Yesterday (25.08.2011) rainfall at Chennai was 156.2 mm.

The all-time record for Monthly in August for Chennai is 336.3 mm recorded 117 years ago during the year 1894. Till yesterday (25.08.2011) the monthly rainfall at Chennai was 329.7 mm. Chennai needs just 6 mm more to break the 117 year record and it has 5 more days to go. I personally think the record will be broken.
