 As the Malayalam Calendar was popular in Kerala, the flood is generally referred to as 'തൊണ്ണൂറ്റി ഒമ്പതിലെ വെള്ളപ്പൊക്കം' ("Thonnootti Onbathile Vellapokkam" which translates to "flood of '99").The rain continued for about three weeks.Many districts of present-day Kerala were deeply submerged by the flood - from Thrissur, to Ernakulam to Idukki, Kottayam even up to Alappuzha and Kuttanad.
