Pacific strengthens flood early warning systems

Pacific nations are bolstering their defenses against escalating flood risks by strengthening their early warning systems. A regional training program, underway this week in Nadi, Fiji, brings together technical experts from National Meteorological and Hydrological Services across the region.

The Early Warning System for Floods (EWS-F) Implementation Training, running from August 17 to 21, 2026, is a key component of the Pacific Early Warning System for Floods Project. This project aligns with the global Early Warnings for All initiative, aiming to equip communities with timely and actionable information.

Misaeli Funaki, Director of the Fiji Meteorological Service, highlighted the multifaceted nature of effective flood warnings. "We need reliable data, good forecasting systems, strong technical capacity, and most importantly, clear and timely information that enables people and decision-makers to take action," he stated during the training's opening.

Fiji and Tonga are serving as pilot countries for operational impact-based flood forecasting, utilizing advanced tools like hydrological observations, data management, and numerical modeling. This pilot phase will test approaches for potential expansion across the Pacific. Funaki stressed that the value of a forecast lies in its effective dissemination and comprehension, ensuring it supports crucial on-the-ground decisions.

The training covers Fiji, Kiribati, Samoa, Solomon Islands, Tonga, and Vanuatu, with coordinated efforts by the World Meteorological Organisation and financial backing from the U.S. Department of State. The Pacific Community is leading the implementation, supported by Earth Sciences New Zealand and national partners. The core message remains clear: early warning must translate into early action to mitigate flood impacts.

A forecast is only valuable when it reaches the right people at the right time and is understood well enough to support appropriate decisions.
