The heavy to very heavy rainfall belt is gradually leaving the south of Tamil Nadu and is lately consolidating over the North and adjoining coastal Andhra Pradesh and Telangana.
Latest satellite pictures suggested as if the rain-generating well-marked low-pressure area (no cyclone, or at least two steps away from being called into one) has stepped out of its pedestal over Sri Lanka and is approaching the Tamil Nadu coast.
The rain belt is now hovering across Chennai-Bengaluru, Nellore-Anantapur, Ongole-Nandyal in Tamil Nadu and neighbouring coastal Andhra Pradesh and Telangana.
Thunderclouds have also farmed out to over Machilipatnam, Guntur, Eluru, Bhimavaram, Rajahmundry, Kakinada, Visakhapatnam, Vizianagaram and Malkangiri, satellite pictures showed.
This showed a northerly movement of the system along the coast, which the European Centre for Medium-Range Weather Forecasts has been predicting for some time now.
