Jammu and Kashmir Lieutenant Governor Manoj Sinha, the Army's Northern Command chief Lieutenant General Upendra Dwivedi, Union Home Secretary Ajay Bhalla, Director of Intelligence Bureau Tapan Deka were among the top functionaries who attended the meeting

The home minister reviewed the preparations for the Amarnath pilgrimage with top officials of the central government, Army and the Jammu and Kashmir administration, the sources said. Shah also took stock of the plans being formulated to ensure foolproof security for the pilgrimage, they said

Last year, 3.45 lakh people visited the holy cave and this year, the figure could go up to 5 lakh. The sources said that to avoid any incident like last year's flash flood which claimed 16 lives near the shrine, the National Disaster Response Force has started identifying ideal locations for setting up pilgrim camps keeping in mind any possible unforeseen natural disaster

Indian Air Force helicopters are expected to be deployed to carry out aerial sorties in the upper reaches of the holy cave to check for glacial events and the formation of lakes that may trigger flash floods downhill. Last year, such sorties were conducted only after the flash floods occurred in June, but this year, the exercise will be undertaken before the start of the pilgrimage and at continuous intervals during the two-month yatra.

The aerial surveys may be conducted by a team with expertise in remote sensing and satellite, hydrology and disaster response. Once a dangerous water build-up is spotted, contingency measures will be taken all along the pilgrimage route, especially in the areas near the cave shrine, they added. Recently, a lot of snow has been found along both the tracks - Baltal and Pahalgam - leading to the holy cave and therefore the Border Roads Organisation has been given the task to clear the snow by June 15
