Cyclone Helen (2013)

Late on 17 November, the remnant energy of Tropical Storm Podul contributed to the development of a trough over the Bay of Bengal, located near the Andaman Islands.

Later on the same day, the India Meteorological Department (IMD) upgraded the storm to a depression, classifying it as BOB 06, followed by the JTWC reporting that the storm had reached Tropical Storm strength. A couple of hours later, the IMD upgraded BOB 06 into a Deep Depression, as the storm continued to intensify. The storm slowly drifted west-northwestward, while deep convection consolidated around the system's well-defined center of circulation. In the early hours of 20 November, the IMD classified BOB 06 as a Cyclonic Storm, thereby officially naming it Helen. Early on 21 November, Helen continued to intensify into a Severe Cyclonic Storm, reaching its peak intensity of with a central pressure of . Shortly before landfall, the storm's convection sheared to the north, causing its low-level circulation to fully expose followed by the JTWC issuing its final bulletin, reporting that the storm had weakened due to land interaction. Helen made landfall south of Machilipatnam, Andhra Pradesh and rapidly deteriorated into a deep depression. == Preparations and impact ==
