The rains in January came as a surprise to many as the northeast monsoon season ends at the end of December. Weather blogger K Srikanth who runs the Chennai Rains blog said that rains were a result of the La Nina effect. He said, "La Nina basically leads to good monsoon and La Nina conditions can lead to the monsoon extending till or after December which is why we are experiencing rains."

Another weather blogger Pradeep John running the page Tamil Nadu Weatherman predicted heavy rains for parts of Tamil Nadu, but forecast lesser rains for the city on Wednesday. "A rare spell to remember for lifetime in Chennai. On Wednesday, north coastal TN, interior/ West, South TN will get rains. It looks good for coastal areas, interiors and south TN (sic)," he wrote.

On Tuesday, heavy rains resulted in inundation and waterlogging in many parts of Chennai. Commuters waded through the waters in arterial streets.  Traffic was affected in many parts of the city.
