2016 Indian Ocean cyclone season

Under the influence of a persistent area of convection, a low pressure area formed in Malay Peninsula and adjoining north Sumatra. It emerged as a tropical disturbance in the following days as it was moving slowly towards southeast Bay of Bengal. On 6 December, The IMD classified the system as Depression BOB 06 as it had sufficiently organized itself with winds exceeding 45 km/h (28 mph). Owing to low wind shear and favorable sea surface temperatures, the storm gradually intensified into a deep depression the following day. Skirting off the Andaman and Nicobar Islands as a deep depression, BOB 06 was upgraded to a cyclonic storm by the IMD and JTWC in the early hours of 8 December, assigning it the name Vardah.

Gradually intensifying as it moved westwards, Vardah reached its peak intensity on 11 December with winds of 80 mph (130 km/h) and a minimum central pressure of 982 mbar (29.00 inHg).
