People going to tonight's sold-out Super Rugby final could do well to pack a raincoat, with strong winds and rain forecast to buffet the capital.Multiple regions, including Wellington, remain under orange heavy wind and rain warnings as stormy weather moves over southern and central New Zealand today and into tomorrow.As the Hurricanes and Chiefs kick off at Hnry stadium at 7.05pm, the 34,000 in attendance can expect things to get a little wild.MetService meteorologist Gerard Bellham said gusts could reach up to 90km/h in the stadium during the game."There will also be some showers coming through with those strong winds, so that'll be swirling around, as it does in Wellington, and because of the shape of the stadium it does tend to swirl around a bit."However, the rain was not expected to be too bad."The other thing too is it's actually going to be quite warm, about 16 degrees during the game, which is quite unusual for this time of year."A Wellingtonian himself, Bellham said it would make tough going for the players."I played for the mighty Eastboune Rugby Football Club so I do feel for them," he said."Some of the games we'd play, we'd kick the ball for touch and it would land in the sea."He believed the weather would give the Hurricanes a home-town advantage - "What's the name? I'll say no more."Meanwhile, flooding forced the closure of State Highway 6 between Haast and Makarora earlier. This has since reopened, with NZTA advising drivers to be wary of remaining surface water.The highway was also closed between Rapahoe and Nine Mile in the Grey District due to a slip. This has since reopened, with NZTA advising drivers to expect delays as the road remained under stop/go control.All warnings are expected to lift by the early hours of Sunday, with the MetService forecasting only scattered rainfall for the Winter Solstice.
