Interpretation : Low level easterly Winds atlast will move into interiors later in the day with Ex Burevi (now Low Pressure Area (LPA)) becoming too feeble. Atlast Interiors and west TN has chance of rains. Chennai and other coastal districts like Cuddalore, Delta, Pondy will get pull effect rains from the activated easterlies with circulation in the other side.
When low in Gulf of Mannar, the convergence of winds rarely happens in interiors and most of the rains will be limited to areas in Coast and districts nearby to the coast. After 72 hours Burevi which is now a low pressure area (LPA) is expected to say Goodbye to Tamil Nadu. Over 72 hours in same region. It is the best rainfall Cyclone for Tamil Nadu since Nisha in 2008. Burevi will be spoken and remembered for years to come, just like Nisha was.
With new circulation in Arabian Sea, next 3 days we will see easterly winds moving in easily and interior districts will get rains. Districts like Erode, Coimbatore, Tiruppur, Nilgiris, Dindigul, Theni, Virudhunagar, Thenkasi etc. Other districts will also get moderate rains.
Chennai and KTC – Pull effect rains for the next few days till Wednesday morning and then we go for a long break. These pull effect rains can give intense short spells at times. The peak rains will always happen in nights to mornings while we sleep.
