Cause Of Up-coming LPA :
* Even when we are at the withdrawal stage of South-West Monsoon, a low pressure area has been formed over the Andaman Islands.

* This is due to the influence of a cyclone in the China Sea and Gulf of Thailand, which has fuelled an normal UAC (Upper Air Circulation) to form as a Low Pressure Area.
What Is Gonna Happen.?
* Therefore, The SW Monsoon Withdrawal is expected to delay by a week to 10 days, resulting in delay of NE Monsoon Onset.
* Remember, this is La Nina Year, in which we( Tamil Nadu) can expect above normal rainfall during North-East Monsoon.
* The LPA is expected to promote itself as a cyclonic circulation and move towards Central-North Andhra Pradesh.
* But before making its oandfall, it's getting weeker, as there isn't fuel present anymore in the Bay. Here, fuel means weaker MJO, weaker Rossby Wave, weaker SST (Sea Surface Temperature).
What Is La Nina.?
* Generally, El Nino and La Nina occur every 4 -5 years.
* La Nina causes drought in the South American countries of Peru and Ecuador, heavy floods in Australia, high temperatures in Western Pacific, Indian Ocean, off the Somalian coast and a comparatively better monsoon rains in India.
What We Can Expect.?
* The LPA on moving towards AP Coast, will bring good pull-effect rains in East Coastal areas of Odissa, AP, and Tamil Nadu.
* Wind speed will increase from tomorrow over coastal areas, and therefore fishermens are asked not to venture into the Bay of Bengal Sea.
* KTCC positions directly over the wind converging part of the cyclonic circulation, where the tail of the circulation will be just above KTCC. Hence, we can expect massive thunderstorms from Saturday Noon till Monday Noon.

* Temperature is going to reduce drastically from tomorrow post noon, over Chennai and Other East Coast Areas.

* KTCC can expect good rain shows on Saturday Evening / Night.
* Sunday whole day will be clouds covered, as we can see whole day has presence of dark high-clouds, which will bring continuous light to moderate rains whole day. Also wind speed will be more, as the low procresses nearby.
* Monday will be an Haze type of climatinc condition, will be clouds covered and with little passing showers here and there.
* From Tuesday onwards, the haze weather is expected to continue, with reduce in temperature.

Conclusion :
* Since we are at the monsoon withdrawal phase (South West Monsoon), there will be delay in North-East Monsoon Onset.
* Although there will be some delay (7-10days approx.), it doesn't mean that the strength of North-East Monsoon will be reduced this year.
* Remember 2015 Flood, which falls under La Nina Year.?
* This weekend is going to be perfect for North Coastal, North Interior and Delta TN.
