Well Marked Low Update : The Well Marked Low currently appears to be over South West Bay interacting over the Sri Lankan landmass and is expected to move towards the Indian coast by today.  It could possibly cross coast around the Delta region. Under the influence of this Well Marked Low North Coastal Tamil Nadu will continue to get widespread rains with some places getting heavy to very heavy rains today. Going by the current long term radar images it appears the stretch between Nellore to Pondicherry could possibly hit by spells of very heavy rains over the next 6 – 12 hours.  As the Low moves up towards Indian Coast the rain bands will shift to South AP / Central AP towards the late evening / tonight

As the Well Marked Low nears Indian Coast expect wind speeds to pick and squally condition to prevail over coastal Tamil Nadu. Marginal intensification may be expected from this Well Marked Low once it comes back to open waters after moving away from the Sri Lankan landmass.  It could possibly attain Depression status during the day today and cross the Tamil Nadu Coast as depression.

The situation is fluid at the moment on account of the Sri Lankan landmass interaction and possible intensification once it reaches open waters.  Also as the system moves up North the rain prospects could start improving for parts of Coastal Andhra Pradesh as well.  Delta region could see heavy rains during the landfall towards the evening.

Chennai Weather Update: Heavy rains to continue during the early part of the day with very heavy spells slowing down from evening possibly with the rain bands shifting to North of Tamil Nadu as the Low moves up North.
