It is unusual to see so many cyclones in the South Pacific at this time of the year, says Tonga's Director of Meteorology, 'Ofa Fa'anunu today, as northern Tonga remains on a Warning for Tropical Cyclone Ella [upgraded to Category 2 this evening 10 May 2017]. Tonga has not experienced an out of season cyclone since Severe Tropical Cyclone Keli in JuneĀ 1997.
