Island weather: Snow and flooding close two highways"},"content":{"rendered":"<p class=\"DsYfyjGuqRwC\" style=\"display:none\">MetService had forecast heavy snow above 600m, with lesser amounts down to 400m, before conditions eased from the south overnight.<\/p>\n<p class=\"DsYfyjGuqRwC\" style=\"display:none\">Meteorologist Sophie Huntington said snow was expected to have largely cleared from the lower South Island before dawn, but urged motorists to remain cautious on roads this morning.<\/p>\n<p class=\"DsYfyjGuqRwC\" style=\"display:none\">\u201cAs it\u2019s colder overnight, it\u2019s not going to melt as much as it would in the daylight,\u201d she said.<\/p>\n<p class=\"DsYfyjGuqRwC\" style=\"display:none\">\u201cOnce the day breaks in the morning, that should help melt any that\u2019s about.\u201d<\/p>\n<p class=\"DsYfyjGuqRwC\" style=\"display:none\">The snow risk shifts further north this morning, with road snowfall warnings in place for Porters, Arthurs and Lewis passes.<\/p>\n<p class=\"DsYfyjGuqRwC\" style=\"display:none\">Between 2cm and 5cm could accumulate near the summit of Porters Pass before 11am, with lesser amounts down to 500m.<\/p>\n<p class=\"DsYfyjGuqRwC\" style=\"display:none\">Around 1cm or less is forecast near the summit of Arthurs Pass between 4am and 10am.<\/p>\n<p class=\"DsYfyjGuqRwC\" style=\"display:none\">Rain could turn to snow above 800m on Lewis Pass between 9am and 2pm, with about 1cm possible near the summit.<\/p>\n<p class=\"DsYfyjGuqRwC\" style=\"display:none\">Temperatures were also forecast to dip below freezing in places, with Twizel reaching -2C and Alexandra -1C.<\/p>\n<p class=\"DsYfyjGuqRwC\" style=\"display:none\">\u201cIt\u2019ll be chilly, definitely, but not what we were experiencing a month ago,\u201d Huntington said.<\/p>\n<p class=\"DsYfyjGuqRwC\" style=\"display:none\">Further north, the front is bringing heavy rain up the West Coast.<\/p>\n<p class=\"DsYfyjGuqRwC\" style=\"display:none\">Huntington said Westport and the wider Buller area would be waking to wet conditions as the slow-moving system reached the northwest of the South Island.<\/p>\n<p class=\"DsYfyjGuqRwC\" style=\"display:none\">A heavy rain watch is in force for Buller until 1pm, with rainfall amounts potentially approaching warning criteria, particularly about the ranges.<\/p>\n<p class=\"DsYfyjGuqRwC\" style=\"display:none\">Haast recorded 9.2mm of rain in the hour to 5pm yesterday, Huntington said.<\/p>\n<p class=\"DsYfyjGuqRwC\" style=\"display:none\">\u201cIt\u2019s still going to be heavy in those Buller, Westland areas, but not as bad as it was earlier.\u201d<\/p>\n<p class=\"DsYfyjGuqRwC\" style=\"display:none\">The system was expected to weaken as it travelled north, while conditions were expected to improve across much of the South Island behind it.<\/p>\n<p class=\"DsYfyjGuqRwC\" style=\"display:none\">Rain is forecast to develop around Wellington and surrounding areas during the afternoon or evening.<\/p>\n<p class=\"DsYfyjGuqRwC\" style=\"display:none\">Auckland can expect cloudy periods and isolated light showers before showers become more frequent in the evening, when brief heavy falls are possible.<\/p>\n<p class=\"DsYfyjGuqRwC\" style=\"display:none\">\u201cIt might be heavy but quite short-lived,\u201d Huntington said.<\/p>\n","protected":false},"excerpt":{"rendered":"MetService had forecast heavy snow above 600m, with lesser amounts down to 400m, before conditions eased from
