Posted 10th Saturday Night:

"Vardah" a very severe cyclonic storm in the Bay at 13.2N and 86.3E...Sustained winds (1 minute average) estimated at 65 kts and gusting to 80 kts,and estimated core pressure at 985 mb.

One of the main factors that guide and steer the track of such storms is the Sub Tropical Ridge. Now, as a change, we see this ridge as deep layered, Also, the ridge is showing positive signs of extending towards West  into the Bay of Bengal. 

Latest Expectation: Thus, from the current NW track, "Vardah" will start tracking towards the West along the 15N line after 12hrs ( from this report).
Will start weakening in 24 hrs ( from Saturday Night period) and cross South A.P. coast on 12th December.

Chennai: Sunday cloudy and windy with about 10 mms of rain. Rains and winds increasing on Monday. Monday: Cool at 24c with overcast skies and very windy. Chennai can expect about 40 mms Sunday Mid night- Monday mid night.Decrease in rains from Tuesday.

Next Update on 11th Sunday at 6 pm IST
