Fiji: Adverse weather forecast across much of the country through at least Sept. 26

Heavy rainfall forecast across much of Fiji through at least Sept. 26. Flooding and associated disruptions possible.

Warning

Event

Heavy rainfall is likely across much of Fiji through at least Sept. 26. As of Sept. 25, the Fiji Meteorological Service has issued a nationwide heavy rain alert through at least Sept. 26. Showers and thunderstorms are likely across the warning area, with isolated heavy downpours. A flood warning remains in place for the Wainibuka and Wainimala rivers, while a flood alert is in effect for downstream of the main Rewa River from Navolau Village. Floodwaters in the upper catchment of the rivers have affected low-level roads near small streams, culverts, and flood-prone areas. Officials could update and possibly extend the coverage of weather alerts over the coming days.

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 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 heavy rainfall has saturated the soil. Disruptions to electricity and telecommunications services are possible where significant flooding, strong winds, or landslides impact utility networks.

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 airports across the affected region. If strong winds trigger hazardous sea conditions, authorities may temporarily suspend port operations or close beach fronts.

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.
