The weathermen has predicted now that a new low pressure intensifying in the Bay of Bengal is expected to bring moderate rainfall to Chennai city plus in the neighbouring districts by this weekend. In the next three days, the weather system is likely to intensify to a depression and there would be moderates to heavy rainfall in north Tamil Nadu and in coastal districts of south Andhra Pradesh. As per the weather bloggers there were chances of system turning into a cyclone but as per the officials belonging to IMD it was too early now to predict its intensity when it hits the coast.

It is revealed by IMD that the low pressure area over equatorial Indian Ocean and adjoining central parts of south Bay of Bengal with associated cyclonic circulation is still persisting. In the next 48 hours, the system is likely to become more marked and in the subsequent 24 hours it is likely to concentrate to a depression. An official belonging to IMD predicted that the system is likely to move north-westwards towards north TN and south AP coast.

Mr. S. Balachandran, deputy director, IMD, hinted that there would not be any rains in the next 3 days and the team members are continuously monitoring the system. He expressed his uncertainty about the system intensifying further after it becomes depression and said it is important to wait and watch. By this weekend the system might intensify into a cyclone and this was according to the weather bloggers. By 14th December, the system is most likely to become a cyclone. As per the Chennai citys popular weather blogger, Mr. Pradeep John, in another couple of days of time clarity about the location of the landfall would be got and it is too early now. The chances of system intensifying into cyclone are low and this was as per Skymet Weather prediction. It also forecasted that it might become a deep depression at the most.

Mr. Mahesh Palawat who is the chief of Skymet Weather, expressed his views. He spoke about how coastal districts in north TN including Chennai city would get moderate to heavy rains beginning from Friday. He was unsure of the system intensifying into a cyclone but was sure about the rains in north TN and Chennai. One important point here is till last week weather models indicated that the system would disappear after turning into a well marked low pressure. The presence of favourable conditions in the sea and in the atmosphere is making the system to be gathering more steam now. This is now shown by the weather models. The system is now lying over the south Bay of Bengal and parameters such as low vertical wind shear, low atmospheric pressure and high sea surface temperature are adding more strength to the system.

Mr Palawat later spoke about how in the month of December weather systems usually form in south Bay of Bengal due to high sea surface temperature. It has been forecasted by the IMD that the skies in the Chennai city would be cloudy for the next 48 hours.
