An unseasonable cyclone that swept up through the Bay of Bengal and wreaked havoc on the Indian state of Orissa also dumped a heavy snowfall on the Nepal Himalaya, shutting down trekking routes from the Annapurnas to the Khumbu. The storm was ominously reminiscent of the 1995 surprise snowfall in the peak trekking season that killed dozens of people and forced hundreds to be evacuated.
