Chennai and other North TN coast can see very good rains today till tuesday with breaks. Tomorrow and Tuesday too there will be good rains. How the rains will pan out will be known only based on the now casting and how clouds converge. As of now, rains are confirmed to 100% and we can expect decent nos of rainfall. Dont fear about floods too, it wont happend with these type of spells.
Winds are east and which means, the rains will be mostly limited to North TN belt
I have added the map showing the broad trough low and how it is pushing the moist winds to the north TN coast and creating convergence.
Down in the Delta, as the steering winds are east, clouds will move into interior districts of Delta such as Trichy, Ariyalur and Perambalur districts too. just like how vellore and thiruvannamalai got rains yesterday
