Tamil Nadu gets water logged in low lying areas due to the onset of Northeast monsoon or retreating monsoon.
Private weather blogger Pradeep John said there will be a dramatic change in weather conditions and sharp spells of rain.
He also said, “MJO (Madden Julian Oscillation) effect, an equatorial wave which enhances rainfall, is to come into our basin. So it is going to be above-normal monsoon rain this year.”
