Present Position of low
Low is still positioned East North East of Lanka and since it is far away from our coast, the coastal belts are getting heavy rains, Mayiladuthurai district is being pounded as we post this. Today too Delta to Chennai coast will be in hot spot while nearby districts like Villupuram, Ariyalur, Perambalur, Thanjavur, Salem, Thiruvannamalai, Ranipet, Vellore will all get moderate rains.
When interiors, west and south TN will get
When low moves close to nagai coast, then the winds will enter into the interiors and that is the time interiors and west will get heavy rains, till that time, they will get only light to moderate rains. We can see how convergence is limited to coast in today wind pattern. So konkam patience for western, south and interior heavy rains, while you can enjoy the showery moderate rains today. The low is expected to push a pulse into Arabian sea and there near Kerala coast low will intensify and move away, so pull effect rains is possible on 13/14th November.
Chennai what is expected
On day 1, widespread rains ranging from 6-9 cm have recorded in the city, we have estimated that around 30 cm is expected to fall over 11-14th, November. With 3 more days to go and heaviest rains ahead of us, the target is expected to be achieved. Chennai and its co region of KTC will get breaks with rains through out the day and as usual the moon time to morning times, the rains during this period will be the peak ones. The spells will be of varying intensity. Even in day time sudden burst will happen with low being near the coast. Right now if you can see the above images, we can see line of clouds for 100s of kms north east of Chennai.
