Gita has gone and a large high is moving in behind it to bring a mostly dry, warm, weekend. However by Sunday the westerlies will be picking up in the South Island as a new low starts to develop in the Southern Ocean.
This low is being partially fuelled by the remnants of what was Cyclone Kelvin. This tropical rain is currently moving down through central Australia and will track into the Southern Ocean this weekend.
From late Sunday and across Monday and Tuesday next week both islands will be affected.
It is not a storm, but there may be some heavy rain in the west and some localised gusty winds too.
