The following are provided by the Fiji Meteorological Service: Check their website for any current warnings or alerts.
· 5 to 7 tropical cyclones (TCs) could occur in the Regional Specialized Meteorological Centre- Nadi (RSMC-Nadi) Tropical Cyclone Centre (TCC) Area of Responsibility (AoR) between November 2022 to April 2023.
· Within the RSMC-Nadi TCC AoR, 3 to 6 tropical cyclones or average to above average cyclone activity is expected West of the International Date Line, while 2 to 4 tropical cyclones or average cyclone activity is expected to the East of the International Dateline.
· For the coming season, 1 to 4 tropical cyclones are anticipated to reach or exceed Category 3 strength, in the RSMC-Nadi TCC AoR.
· The La Nina phase has returned and remains active in the region which is a key factor in the tropical cyclone outlook. This is the 3rd consecutive year that the tropical cyclone season has occurred during a La Nina phase. La Nina is expected to continue until the end of 2022.
· The peak period for the tropical cyclone season in the RMSC-Nadi TCC AoR is usually between January to February.
· While the tropical cyclone season is between November to April, occasionally cyclones have formed in the region in October and May and rarely in September and June. Therefore, an out-of-season tropical cyclone activity cannot be totally ruled out.
· Tropical disturbances and depressions that do not attain tropical cyclone intensity or low-pressure systems as a result of decaying cyclones, can still cause strong winds/gusts, widespread rainfall, landslides, and potential flooding.
· Due to widespread flooding, there is also the potential for the outbreak of waterborne diseases in the local communities, as previously experienced during post-flooding events.
· With the current La Niña event and increasing chances of above-average rainfall, there are also chances of coastal inundation to be experienced.
· 2 to 3 total tropical cyclones are likely to pass through Fiji’s Exclusive Economic Zone during the 2022-23 tropical cyclone season.
· 1 to 2 tropical cyclones are likely to reach severe category (Category 3-5) during the season.
· Most of the past tropical cyclones during La Niña Tropical Cyclone seasons have approached the Fiji Group from the northwest quadrant. Therefore, there will be elevated risks for the Western Division this season.
· With the recent re-establishment of a La Niña event and chances of it continuing until year-end, there is a high chance of receiving above-average rainfall, which may lead to flooding across the Fiji Group, during the TC Season.
· While the tropical cyclone season is between November to April, occasionally cyclones have formed in the region in October and May and rarely in September and June. Therefore, an out-of-season tropical cyclone activity cannot be ruled out.
· Tropical disturbances or depressions that do not attain TC intensity or low-pressure systems that are a result of decaying cyclones, can still cause widespread rainfall and potential flooding.
· All communities should remain alert and prepared throughout the 2022/23 TC Season and please do take heed of any TC warnings and advisories, to mitigate the impact on life and properties.

FIJI CLIMATE OUTLOOK FEBRUARY 2023; FEBRUARY TO APRIL 2023; MAY TO JULY 2023
• Rainfall during February 2023 is likely to be above normal for the Western Division, with near-normal or above-normal rainfall expected for the rest of the country. There is little guidance for Rotuma with almost equal chances of below-normal, near-normal, and above-normal rainfall.
• For February to April 2023 season, normal or above normal rainfall is likely across the country, while normal or below normal rainfall is favored for Rotuma.
• During May to July 2023 season, normal or above normal rainfall is likely across the Fiji Group, while there is little guidance for Rotuma with almost equal chances of below normal, near normal, and above normal rainfall.
• The air temperatures are likely to be above normal across the country during February 2023, as well as February to April 2023 season.
• A weak La Niña event continues to persist in the tropical Pacific Ocean.
• Climate models on average suggest a return to ENSO-neutral conditions from February to April 2023.
• Despite the likely easing of the La Niña event, its impact on Fiji is likely to continue over the next couple of months due to lag effects.

· A weak La Niña event continues to persist in the tropical Pacific.
· The La Niña event is expected to weaken to ENSO neutral state (neither El Niño nor La Niña) through the February to April 2023 period.
· While the ENSO-neutral state is favored to continue for the rest of the 1st half of the year, there is great uncertainty in the ENSO state for the latter.
· Fiji usually experiences above-normal rainfall during a La Niña event, which can lead to flooding, especially during the wet season, which is from November to April.
