He has advised locals and tourists not to venture out in the high hills of Shimla, Kullu, Sirmaur, Chamba and Kinnaur districts as chances of heavy snow and avalanches are high.
Even the snow-bound areas near the tourist resort of Manali like Solang, Beas Kund, Nehru Kund, Gulaba and Marhi have been declared avalanche-prone.
