The paper addresses on the devastating episode (17-18 June 2013) at Kedarnath (Uttrakhand, India). The disaster caused huge loss of lives and physical/material wealth. To understand this catastrophic event, rainfall/convective data and associated climate meteorological parameters are investigated to understand the causes of disaster. The cause of disaster seems to be the heavy and continuous rainfall associated with snow melting and over flooding/collapse of the Chorabari Lake, located upstream.
