Before reading further, please take a look at the IMD definition of intensity rainfall. This is the 1st low pressure in this NEM moving towards Tamil Nadu coast. The previous two went away from our coast and then came dry days. The present low pressure in Bay of Bengal is likely to intensify into Depression today and is also likely to intensify further into Deep Depression by 30th or atleast by December 1st morning and cross Tamil Nadu Coast between Nagapattinam and Chennai on 1st/2nd December. Mostly around cuddalore belt. Some gusty winds of 50-60 km/hr can be expected at that time.
