A moist southeasterly wind flow is in place across the islands, bringing widespread cloud and showers with the risk of isolated heavy falls and afternoon thunderstorms, particularly over Viti Levu and Vanua Levu. Winds are expected to be moderate to fresh from the southeast with moderate to rough seas. The National Weather Forecasting Centre advises that localised heavy falls may lead to flash flooding in low-lying and flood-prone areas.
Areas most likely to see frequent showers and isolated heavy falls through to midnight tomorrow include Serua‑Namosi, Navua‑Suva‑Nausori, Tailevu‑Naitasiri‑Ra‑Rakiraki, southern Bua, Cakaudrove and eastern Macuata. Taveuni, nearby smaller islands, the Lau and Lomaiviti groups, Kadavu and surrounding isles will have cloudy periods with some showers. Elsewhere conditions will generally be fine apart from the usual afternoon or evening showers, but afternoon thunderstorms with heavy falls are expected over Viti Levu and Vanua Levu.
Residents in low‑lying or flood‑prone locations should be aware of the potential for rapid runoff and flash flooding where heavy falls occur. Rainfall is expected to be locally heavy at times during thunderstorms, and those in vulnerable areas should take appropriate precautions until conditions ease.
On the coast and at sea, southeasterly winds will be moderate to fresh with moderate to rough seas, so small craft operators and swimmers should exercise caution. Rotuma currently has a moderate easterly flow with cloudy periods and some showers; a trough of low pressure is expected to affect the island from later tomorrow, bringing showers that become occasional and an increased chance of isolated thunderstorms.
The outlook for Saturday remains similar: cloudy periods with some showers over Serua‑Namosi, Navua‑Suva‑Nausori, Tailevu‑Naitasiri‑Ra‑Rakiraki, southern Bua, eastern Macuata, Cakaudrove, Taveuni, Lau and Lomaiviti, and Kadavu, with afternoon thunderstorms and heavy falls expected again over Viti Levu and Vanua Levu. Winds are forecast to be moderate to fresh southeasterlies with moderate to rough seas. Key centre notes: Navua/Suva/Nausori expect occasional showers, isolated heavy falls and evening thunderstorms (today’s max 32°C; tomorrow min 25°C, max 32°C); Nadi/Lautoka/Ba remain mostly fine aside from afternoon storms (today’s max 34°C; tomorrow min 23°C, max 34°C); Labasa should see showers easing later today (today’s max 34°C; tomorrow min 23°C, max 34°C).
