Heaviest rainfall is expected on the coastal stretch between Sriharikota and Nellore.

Meanwhile, squally weather with wind speeds of 40-50 kmph, gusting to 60 kmph, is likely to commence along and off the north Tamil Nadu and Puducherry coasts. Wind speeds are expected to increase to 55-65 kmph, gusting to 75 kmph, from Sunday night until Tuesday morning before gradually weakening.
