Fiji: Adverse weather forecast nationwide through at least Jan. 10 /update 3
Severe weather forecast across Fiji through at least Jan. 10. Flooding and transport, business, and utility disruptions possible.
Event
Heavy rainfall, thunderstorms, and strong winds are forecast to continue across Fiji through at least Jan. 10. There is a risk of flash flooding in some low-lying areas due to the heavy rainfall.
As of Jan. 7, the Fiji Meteorological Service issued a heavy rain warning for the northern and Viti Levu divisions, Yasawa and Mamanuca groups, Kadavu, and nearby smaller islands. Rounds of heavy rainfall and squally thunderstorms are likely over the Northern Division while occasional heavy rain and a few thunderstorms are forecast over the rest of Fiji. A flash flood warning is in place over low-lying and flood-prone areas of Vanua Levu while a flash flood alert has been issued over low-lying and flood-prone areas of Nadi through Lautoka, Ba, Tavua, and Rakiraki to Korovou.
Possible impacts of the adverse weather include flash flooding of low-lying and flood-prone areas, landslides, lightning strikes during thunderstorms, poor visibility at sea and on land, and flooding of water bodies. Officials could update and possibly extend the coverage of weather alerts over the coming days.
Hazardous Conditions
Sustained heavy rainfall could trigger flooding in low-lying communities near rivers, streams, and creeks. Urban flooding is also possible in developed areas with easily overwhelmed or a lack of stormwater drainage systems. Sites located downstream from large reservoirs or rivers may be subject to flash flooding after relatively short periods of intense rainfall. Landslides are possible in hilly or mountainous areas, especially where the soil has become saturated by heavy rainfall. Disruptions to electricity and telecommunications services are possible where significant flooding, strong winds, or landslides impact utility networks.
Transport
Floodwaters and debris flows may render some bridges or roadways impassable, impacting overland travel in and around affected areas. Ponding on road surfaces could cause hazardous driving conditions on regional highways. Authorities could temporarily close some low-lying routes that become inundated by floodwaters. Severe weather could also trigger flight delays and cancellations at regional airports. Authorities may temporarily suspend port operations or close beach fronts if strong winds trigger hazardous sea conditions.
Localized business disruptions may occur in low-lying areas; some businesses might not operate at full capacity because of flood damage to facilities and some employees' inability to reach work sites.
Advice
Monitor local media for weather updates and related advisories. Confirm all transport reservations and business appointments before travel. Make allowances for localized travel delays and potential supply chain disruptions where flooding has been forecast. Do not drive on flooded roads. Charge battery-powered devices in the case of prolonged electricity outages.
