Track of TS 17E

A area of low pressure formed in the Bay of Bengal on 12 November. It gradually drifted northwestwards and organized itself until November 17, when the JTWC issued a TCFA on the system, reporting 30 knot winds at the center. About half an hour following the TCFA, the IMD upgraded the area of low pressure into a Depression, and further into a Deep Depression, the same evening.

Tropical Depression 03B developed a well-defined LLCC with increasing deep convection located to the north of the system. In an environment with moderate vertical wind shear and ample sea surface temperatures, the depression deepened further. The same night, the JTWC initiated advisories on the system, classifying it as a tropical storm with one minute sustained winds of 35 knots.

As of 1:00 PM IST (7:30 AM UTC), 18 November 2012, Tropical Storm 03B was located near latitude 16.0°N and longitude 88.0°E, about 900 km east-northeast of Chennai, 550 km east-southeast of Visakhapatnam and 500 km southeast of Paradip. The system is forecast to intensify further into a Cyclonic Storm and move westwards during the next 12 hours, and then west-southwestwards towards the coasts of south Andhra Pradesh and north Tamil Nadu in the subsequent 72 hours. The Dvorak intensity of the storm is T2.0
