The IMD on Sunday issued an alert for extremely heavy rainfall till Monday at one or two places in sub-Himalayan West Bengal, where normal life has been affected in some parts due to incessant downpour.
Cautioning about the possibility of landslides in the hilly areas of Darjeeling and Kalimpong districts and inundation of low-lying areas in the plains of north Bengal, the India Meteorological Department advised authorities to take necessary action.
The weather office office issued an alert for Darjeeling, Kalimpong, Jalpaiguri and Alipurduar, warning of heavy to very heavy rain at some places with extremely heavy downpour at one or two places till Monday morning.
