Two Scenarios for the upcoming System around 18-20th November.
If the low pressure intensifies to Deep Depression or Cyclone and maintains intensity, it will move up and go to Central & North Andhra with West - NW direction with steering winds of mid to upper level winds around the ridge extending from west pacific.
After becoming cyclone / Deep Depression it has to weaken to low pressure, then it will be pushed to South AP / North Tamil Nadu by the low level winds.
Please see the images, it will make u understand how cyclone steering is done by ridges and low level winds. It is easy to understand. Ithuku mela, u should only track and interpret what is going to happen, as we go ahead into next week.
