Similarly the Tamil Nadu Agri University weather station at Thiruporur recorded 20 mm rains till 3:00 AM.  There are firm indication Northeast Monsoon Onset could be today thanks to rains in many coastal areas around Central TN

With the firm support of Easterlies the coastal areas of Tamil Nadu have started getting rains from yesterday.  Areas between Cuddalore & Nagapattinam received moderate rains from last evening with rains in one or two places continuing well into the night.

With the Low Pressure Area still parked east of Sri Lanka Delta region around Nagapattinam could receive another good day of Northeast Monsoon rains today as well.  The coastal areas between Pondicherry and Vedaranyam stand a good chance of fairly heavy spells of rains at times.
