Just as many interior parts of Tamil Nadu was looking at a possible complete failure of Northeast Monsoon Cyclone Ockhi came in as a blessing in disguise to bring some rains to the districts of Erode / Dharmapuri / Krishnagiri / Vellore etc. In particular the last couple of days saw a classic case of why a strong Arabian Sea system could work out beneficial to larger parts of Tamil Nadu due to the moisture dragged by these systems across the land from Bay of Bengal
If Friday was the best day in terms of rains through Moisture incursion as Cuddalore, Villupuram, Tiruvannamalai districts of Tamil Nadu & Pondicherry got battered by non stop rains from late afternoon to midnight yesterday saw parts of Delta district record continuous rains since morning until late night. This though has started to fade away since and will possibly cut off today as Cyclone Ockhi now has moved further west, nearly 600 kms to the W/SW of Mangalore, reducing its influence over the Bay side of Equation.
With Cyclone Ockhi influence fading away and a disturbance in Bay of Bengal to the Far East developing the wind pattern will not be conducive for rains. The next couple of days we are likely to see subdued phase of Monsoon activity that will go a long way in relief and rehabilitation work over Cyclone battered Kanyakumari district while also reducing the flood risk over rest of TN. There could be stray showers along the coast but relatively dry weather conditions are likely to prevail over Tamil Nadu until the Well Marked Low consolidates and moves towards the Indian Coast.
Tomorrow we will try to provide answers for the question of where the next Low could head to & possible areas of impact.
