During break monsoon, its axis gets struck along the foothills of Himalayas, facilitating rains in Tamil Nadu. A similar phenomenon was witnessed in 2011, Srikanth said.
Moderate rainfall witnessed in Northern Tamil Nadu belt on Saturday, due to convection would increase the August rainfall. Districts of Chennai, Cuddalore and Vellore saw sudden spells of rains as slow moving winds reached the coast on Saturday, weather office sources said.

However, the rain forecast to the state seems to be disappointing in the next few days, as warmer temperatures are ahead. “Rains are expected to slow down as thunderstorms are likely to reduce over Tamil Nadu, except for some isolated spells,” Srikanth added.
