The Pacific region is prone to hydro-meteorological hazards, including cyclones, floods, and droughts. The early warning system assessment was conducted under the WMO CREWS programme in Cook Islands, Fiji, Kiribati, Nauru, Niue, Tokelau, and Tuvalu using a multi-hazard early warning system assessment matrix, which was developed based on four pillars for the early warning system suggested by World Meteorological Organization (WMO).
