On late Friday night, PM Modi reached Kerala to take stock of the situation. He was met at the airport by Kerala CM Vijayan along with other leaders.
Earlier in the day, Modi also spoke with Kerala Chief Minister Pinarayi Vijayan and discussed about the situation.
"Leaving for Kerala to take stock of the flood situation in the state," the prime minister tweeted.
"The suffering of the people of Kerala has been in his thoughts for the last few days. He will review the status of relief and rescue operations, and will also undertake an aerial survey of the flood affected areas," the Prime Minister's Office said in a statement.
Modi left for Kerala after attending the last rites of former prime minister Atal Bihari Vajpayee.
Describing Kerala floods as the worst in 100 years, Chief Minister Pinarayi Vijayan on Friday said that the death toll reached 324.
"Kerala is facing its worst flood in 100 years. 80 dams opened, 324 lives lost and 223139 people are in about 1500+ relief camps," Vijayan tweeted on Friday evening.
Earlier on Friday, Supreme Court asked two crisis management panels to explore the possibility of reducing the water level at the Mullaperiyar Dam by three feet to deal with the devastating floods in Kerala and asked Tamil Nadu to "scrupulously obey" any decision taken on the issue.
Emphasising that the critical flood situation needed to be dealt with "focus, concentration and efficiency by all concerned", the top court said it was not an expert to deal with such unprecedented natural calamity and was leaving it to the executive to tackle the situation.
It asked the National Crisis Management Committee (NCMC) and a committee, set up by the top court in 2014 to manage and look after the safety and security of the dam, to coordinate with each other and explore the possibility of reducing the water level from the existing 142 feet to 139 feet.
The Mullaperiyar Dams is located on the Western Ghats near Thekkady in Idukki district of Kerala on the Periyar river.
The rise in flood water in Periyar River due to rains and the opening of shutters of all major dams including Mullaperiyar, Cheruthoni, part of Idukki reservoir and Idamalayar, have severely affected the lives of people in the downstream areas.
