Global Affairs Canada advises against non-essential travel to to Fiji due to Tropical Cyclone Zena.
Tropical Cyclone Zena is expected to sweep Fiji starting April 7, 2016. Transportation, communications, emergency and medical care, as well as water and food supplies may already be disrupted in affected areas due to unusually heavy rainfall, particularly in Nadi and Lautoka, to the west of Vitu Levu. A state of emergency is in effect across the country following Tropical Cyclone Winston, which recently swept through the main islands of Viti Levu and Vanua Levu. If you reside or are travelling to the affected areas, you should monitor local news and weather reports, and follow the instructions of local authorities. Canadians seeking emergency consular assistance in the area should contact the High Commission of Canada in Wellington, New Zealand or the Emergency Watch and Response Centre in Ottawa.
