Temperatures in Samoa dropped from +25/+31°C to +22/+27°C after severe rains - Samoa is situated close to Equator, with significant influence of current La nina phase to precipitation and storm regime.

However, remnants of Cyclone Yasa still should hit parts of New Zealand at the Christmas, with regional floods in northern and western coast.
