The Indian Navy has launched Wednesday a rescue operation to evacuate 800 tourists stranded at Havelock Island in Andamans due to heavy rains. 
"Civil administration requested the Indian Navy to assist them in evacuating 800 tourists stranded due to torrential rains and rough sea," said a statement from the Indian Navy. 
Four Indian Navy ships - INS Bitra, Bangaram, Kumbhir and LCU 38 have been deployed at the Havelock Island to undertake evacuation of the stranded tourists. 
Many tourists have been stranded with no flights and ships due to rough weather. In several areas, there is no mobile phone or internet connectivity. 
A deep depression over Bay of Bengal is bringing heavy rains to the Havelock Island since the last two days. According to the Met office, this deep depression will turn into a cyclonic storm over the next 48 hours over Andaman Nicobar.
