Fiji: Adverse weather forecast to continue across much of the country through at least Sept. 27 /update 1
Heavy rainfall forecast to continue across much of Fiji through at least Sept. 27. Flooding and associated disruptions possible.
Event
Severe weather is likely to continue across much of Fiji through at least Sept. 27. A slow-moving low-pressure trough is expected to bring rainfall and isolated thunderstorms across much of the country through at least late Sept. 27. As of late Sept. 26, the Fiji Meteorological Service has issued a heavy rain alert for Yasawa and Mamanuca Group, Viti Levu Division, Beqa and Vatulele, Kadavu and nearby smaller islands, and Lau and Lomaiviti Groups. Showers and thunderstorms are likely across the warning area, with isolated heavy downpours. A flood alert is in effect for some watercourses in Viti Levu, including downstream of the Nayavu Station in the Wainibuka River, downstream of the Nairukurukur Station in the Wainimala River, and the main Rew River from Navolau Village. 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.
