Some wet weather will be affecting eastern and central parts of New Zealand this week as a low unravels around the lower North Island. Winds will be south east for many places, which means the rain may not make it over the ranges and into very dry parts of Manawatu and Wanganui – but we do hope for some spillover. Meanwhile the rest of the country looks fairly dry – but a sub-tropical low is possible next week according to some computer models.
