2004 Tsunami waves hit Tamil Nadu, Has Tsunami hit Tamil Nadu in the past ?

Reason for heavy rains in South and West Tamil Nadu in next two days

MJO is presently in Phase 2 and the huge convection in Arabian Sea confirms its presence, we might see 1st Low Pressure after NEM onset and with easterlies in place, this low pressure will intensify and will move away from Indian coast. But MJO presence and the low pressure will also strengthens the easterlies thereby resulting good rains between 17-19th November in South and West Tamil Nadu and also in Kerala.

When ever a circulation is in Comorin to Maldives sea, it activates the easterlies by pulling it and as a result there will be enhanced rains in Kerala, South and West Tamil Nadu.

Today and tomorrow – Heavy rains for South Tamil Nadu

As the circulation develops and remains close to Tamil Nadu coast there will be heavy rains and after 19th the Circulation develops into Depression and moves away towards Somalia / Arabia and the rains also reduces for Tamil Nadu. The expected rainfall map shows the possible area. These places need close watch Papaanasam – Manjolai belt in Tirunelveli, Kodaikanal in Dindigul and Coonoor-Mettupalayam stretch in Nilgiris-Coimbatore for very heavy rains.

Chennai & KTC – heading for break and next spell will be around 25/26 November

Some isolated rains till 18/19th here and there. Break in rains from 19 to 25th November. Next spell of major rains for Chennai will be around 25/26 November and this time it will associated with a low pressure or Cyclone.
