A trough, an elongated area of lower pressure that generates weather, has been established over the seas linking Tamil Nadu and adjoining Sri Lanka with south-east Bay. This is where global models suspect that another tropical storm might develop by mid-week next week (around December 5) and move in towards south-east Tamil Nadu. Because of this next week could bring some meaningful and badly needed rain for Tamil Nadu after successive away-going cyclones denied it its due share.
India Met Department has said that rain or thundershowers would break out at many places over Tamil Nadu and Kerala and isolated places over rest of peninsula from Monday.Thundershowers would lash at isolated places over Tamil Nadu during next two days and cover many places, thereafter.
