Fiji: Heavy rainfall, strong winds forecast in Fiji through at least Jan. 28; flooding possible
Heavy rainfall, strong winds forecast to continue in parts of Fiji through at least Jan. 28. Transport disruptions likely.
Event
A trough of low pressure is forecast to continue causing heavy rainfall, thunderstorms, and strong wind gusts for parts of Fiji. Forecasts indicate the weather system will continue to impact Fiji through at least Jan. 28. The Fiji Meteorological Service has warned that the pattern could strengthen after passing Fiji, potentially becoming a tropical cyclone from Jan. 28.
Government Advisories
As of 1630 FJT, the Fiji Meteorological Service has issued the following weather warnings:
Heavy Rainfall Alert: Vanua Levu, Taveuni, and parts of the northern Lau Islands
Flash Flood Alert: Low-lying areas and locations near rivers and streams on Vanua Levu and coastal areas of Viti Levu from Serua to Togalevu
Strong Wind Warning: Eastern Vanua Levu, Taveuni, and parts of the northern Lau Islands
Authorities will likely issue new warnings or update existing advisories throughout the system's progression in the coming days. Weather warnings could remain active even after the system's immediate threat has diminished, as some areas may still be highly susceptible to rain-induced hazards.
Hazardous Conditions
Sustained heavy rainfall could trigger flooding in low-lying communities near streams, creeks, and rivers, as well as in urban areas with easily overwhelmed or a lack of stormwater drainage systems. Sites located downstream of large reservoirs could experience flash flooding after relatively short periods of intense rainfall. Rain-induced landslides cannot be discounted in steep terrain. The system may also produce damaging wind gusts in some areas. Authorities predict winds on average of 50 kph (31 mph), though stronger gusts are possible.
Transport
Inclement weather associated with the storm could trigger localized business, transport, and utility disruptions. Floodwaters and debris flows may render some bridges or roadways impassable, impacting overland travel in and around affected areas. Areal flooding in urban locations could also result in severe traffic congestion, while strong winds will pose a hazard to high-profile vehicles. Heavy rain and low visibility may trigger flight disruptions at regional airports. Disruptions caused by inclement weather and resultant hazards, such as flooding, could persist well after conditions improve. If there is severe damage to infrastructure, repair or reconstruction efforts may exacerbate residual disruptions. Power outages due to uprooted trees and toppled utility lines are possible.
Advice
Use caution in low-lying coastal areas and near streams, creeks, and other waterways due to the potential for flooding. Stockpile water, batteries, and other essentials in advance. If power outages occur, charge battery-powered devices when electricity is available and restrict the use of cellular phones to emergencies only; power down mobile devices when not in use. Keep important documents and medications in waterproof containers. Plan for commercial, transport, and logistics disruptions in areas where flooding is forecast. Seek updated information on road conditions before driving or routing shipments through areas where flooding has occurred. Confirm flights before checking out of hotels or going to the airport; clearing passenger backlogs may take several days in some locations.
Observe strict food and water precautions, as municipalities could issue boil-water advisories following flooding events. Take precautions against insect- and waterborne diseases in the coming weeks.
