India warned Myanmar that Cyclone Nargis was headed for the country two days before it made landfall there, an official said Wednesday. The state-run Indian Meteorological Department had been keeping a close watch on the depression in the Bay of Bengal since it was first spotted on April 28 and sent regular updates about its progress to all the countries in its path, department spokesman B.P. Yadav said. “Forty-eight hours in advance we informed the Burma weather department about the likely area of landfall as well as time and intensity of the cyclone,” Yadav said, using the former name for Myanmar.
