Tropical Cyclone Pam

· Severe Tropical Cyclone (TC) Pam struck Vanuatu on 13-14 March 2015 causing severe widespread damage. As of 28 March there have been 158000 people affected in 21 islands, 11 fatalities. (Source: United Nations Office for the Coordination of Humanitarian Affairs).

· One week into Tuvalu's declaration of a State of Emergency, details of TC Pam's impacts on outer islands remain sketchy. Lack of power and communication on the outer islands has hampered information flow from the islands, however initial reports suggest that Nui, Nukufetau, Nanumaga and to a lesser extent other outer islands, have been substantially impacted by heavy seas and storm surge.
