The weather's not looking that flash for the South Island on Christmas Day. Heavy rain's forecast for the West Coast, while showers with thunder and possibly hail could hit parts of Otago and Southland. MetService said a front was moving northwards over the South Island into early Christmas morning, but would then become slow moving around the northern parts of the island. Meanwhile, orange heavy rain warnings are in place for the ranges in Buller, Westland and Grey districts (from Arthur's Pass northwards) and the Canterbury Headwaters (also from Arthur's Pass northwards) from early this morning, with thunderstorms possible. Heavy rain watches have been issued for the Tasman District, the ranges of the Westland District (from Mount Cook to Arthur's Pass), and the Canterbury Headwaters (also from Mount Cook to Arthur's Pass).
