MetService: “rainfall may reach several hundred millimetres”
The week is going to start off like summer and end in winter as a large storm in the Southern Ocean spreads across the country. Torrential rain, strong winds and thunderstorms are in the forecast for most New Zealand centres over the next 48 to 72 hours and TRN’s Weather Watch Centre is warning flooding is likely. “This is a big storm and rainfall amounts will be very high in some areas.
Government forecaster MetService is also expecting this rain storm to be big. “During the first half of Wednesday northerlies and heavy rain are still likely to affect Coromandel, Bay of Plenty, Taupo and northern parts of Gisborne. The total rainfalls in these areas through Tuesday and Wednesday may reach several hundred millimetres” says MetService. They say their confidence levels are “high” that heavy rainfall will eventuate.
Duncan says Temperatures are expected to be summer-like for the next couple of days right across New Zealand. “With warm, humid, north westerlies temperatures in many centres will reach into the low to mid 20s today and tomorrow, but by the end of the week single digit highs will be expected in the South”. The storm’s southerly side has already blasted Tasmania and Victoria in Australia. “If you go by current conditions there we’re in for a cold end to the week. Current temperatures in south east Australia, including Melbourne, are only 2 or 3 degrees with the wind chill as low as minus 5 in Tasmania – and that weather is moving our way”.
The Weather Watch Centre will closely monitor this storm with regular updates over the next several days.
