WeatherWatch: Flash floods explained, dry skies ahead

Today over New Zealand again the top third of the nation will experience fairly mild conditions. Showers and dry, sunny, spells are expected in the north west flow. Rain and cloud will push into eastern areas too with some heavy falls. Through central New Zealand there will be a combination of wind, cloud and some rain or showers - but a repeat of Auckland's dramatic flooding yesterday is not expected in other main centres through central New Zealand. Southland and Otago will spend another day mostly in single digits after more severe frosts - but blue skies are also likely for most centres except in the east where some cloud is likely with a low risk of a shower for Dunedin.
