Northeast Monsoon – Active Rainy spell awaits Coastal TN

While the interiors had a few good days this week, coastal TN was fairly quite with only isolated spells of rains at a few places.  All this is set to change with possibly the most active spell of Northeast Monsoon expected to kick off from the weekend for Coastal Tamil Nadu.  Starting from Saturday the rains are expected to peak closer to Diwali.

Yesterday saw parts of Chennai receive spells of isolated rains.  The COMK Weather station in Anna Nagar recorded about 36 mm rains in a spell that lasted little more than an hour in the morning.  Areas to the West of Tambaram also recorded the rains with the AWS of India Weather Man at Pozhichalur recording 24.9 mm during the same period.

Northeast Monsoon Update: While Tropical Cyclone “Megh” in a rapid intensification became a tropical cyclone from Well Marked Low in about 24 hours almost skipping the deep depression stage, Bay of Bengal is also slowly churning out its own Tropical Disturbance.  Numerical Models expect the current Upper Air Cyclonic Circulation in South West Bay to trigger a Tropical Disturbance over the next couple of days in Bay of Bengal to the east of Sri Lanka. Under the influence of this evolving Tropical Disturbance rains are expected to pick pace once again for Coastal region from the weekend starting from mid night of Friday / early morning Saturday. The coastal region along the Chennai – Nagapattinam stretch could see heavy rains in a few places tonight or tomorrow early morning.
