“Depression formed over southeast and adjoining southwest Bay of Bengal at 06:00 UTC of 28 October 2012 near latitude 9.5°N and longitude 86.0°E moved westwards and intensified into a deep depression in the morning of 29th October over southwest Bay of Bengal near latitude 9.0°N and longitude 83.0°E, and continued to move westwards and intensified into a Cyclonic Storm, ‘NILAM’ in the morning of 30th October over southwest Bay of Bengal off Sri Lanka coast. The Cyclonic Storm, NILAM then moved northwestwards, crossed north Tamilnadu coast near Mahabalipuram, south of Chennai between 1600 and 1700 hrs IST of 31st October 2012. After the landfall the cyclonic storm, NILAM moved west-northwestwards and weakened gradually into a deep depression and then into a depression over south Interior Karnataka in the morning of 01st November 2012”
The strong winds duration was prolonged further until end of October and part of southern atolls also reported strong wind on 31st October.
RIMES shared its experimental forecast on 29th October 2012 for NILAM Cyclone about the characteristics of the cyclone, The landfall of Cyclone NILAM on 31 October 2012 was well predicted by RIMES WRF experimental forecast.
The six hourly forecast simulations for wind speed and rainfall parameters were shared to MMS.
The Inter Tropical Convergence Zone (ITCZ) shifted southwards close to equator on 5th November and very intense convective clouds formed over southern Maldives.
Torrential rain measured 132 mm in SIX hours caused severe flood in Fuvahmulah - 6 November 2012 .
