Recall of 1994 Severe cyclone - As Chennai fears from Cyclone Nilam

As Chennai is facing threat from a Cyclone Nilam, i just refreshed my memory of similar threats Chennai as faced.

Anyone has memory of 1994 Severe Cyclone that crossed Chennai) – It was the destructive cyclone to hit Chennai in last 20 years or even more.

This cyclone i witnessed it first hand…..to me this created havoc in Chennai. 24 cm rainfall in 24hrs coupled with 120 km/hr winds…. The cyclone scared the shit out of me. I watched the high winds with power cut without sleep. Still its scary. Hope Cyclone Nilam does not make any destruction like this.
