Fiji: Adverse weather forecast across much of the country through Dec. 29

Severe weather is forecast across much of Fiji through at least Dec. 29. As of Dec. 26, a slow-moving low-pressure trough continues to produce periods of rain, heavy at times, and thunderstorms over most parts of the country. Heavy rain hit the country on Dec. 25, causing flooding in Nadi, on Viti Levu; some meteorological stations have recorded as much as 19 cm (7.5 inches) of rain in the period 21:00 Dec. 25-21:00 Dec. 26. The Fiji Meteorological Service is maintaining a heavy rain warning for the whole of the country. Flood and flash flood warnings are in place for flood-prone areas, small streams, and low-lying crossings nationwide. 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.
