Chennai-Rains-1200

During the last 24 hours, Nungambakkam observatory in Chennai has received 101 mm of rain. This is for the first time in the season thatChennai has received 3-digit rainfall.

Looking back at the records, this is the third time in last one decade in the month of October that Chennai has crossed past the figure of 100 mm rains. Although the monthly averagerainfall for Chennaifor the month of October is 315.6 mm, till now the city has recorded just 142 mm of rain. Still, there are 13 days left in October. As a Low Pressure Area is soon expected to develop over Southwest Bay of Bengal off Tamil Nadu coast which will unleash heavy rains over the state. Therefore, chances are bright that Chennai will surpass its monthly average rainfall this year.

Many other parts of Tamil Nadu have also received light to moderate rains and thundershowers during the last 24 hours. These rains were seen mainly over coastal Tamil Nadu and at scattered parts of interior Tamil Nadu.

Now, however rains are expected to decrease over entire Tamil Nadu for at least the next two days. At present, a Cyclonic Circulation present over Arabian Sea is continuously moving Northwestwards while intensifying further. The moisture concentration is happening around this Cyclonic Circulation. So, the rain activities will start reducing over Tamil Nadu and adjoining areas.

Although, there may be an increase in rain activities around October 20 yet again. On October 22 and 23, we once again expect heavy rains to lash many parts of Tamil Nadu. The reason for these enhanced rains will be a Low Pressure Area which is likely to form over Arabian Sea. As this Low Pressure Area will move further Northwest, the rains will further enhance over Tamil Nadu andChennai.

Around October 21 we expect a Low Pressure Area to form over Southwest Bay of Bengal off South Tamil Nadu coast leading to further increase in rain activities. This is when many areas in Tamil Nadu will experience heavy rains including the city of Chennai.
