A stark contrast in weather conditions is forecast for New Zealand this week, with heavy rain watches issued for parts of the South Island and muggy temperatures expected in the North. The forecast comes as an area of low pressure develops in the Tasman Sea.
South Island Braces for Heavy Rain and Potential Snow
MetService has issued heavy rain watches for Fiordland, Westland, Canterbury, and Marlborough. The heavy rain is expected to begin in Fiordland and southern Westland on Monday, then move eastward across the country on Tuesday. Specific watches are in effect from midnight Sunday for Fiordland, 6am Monday for Westland south of Franz Josef Glacier, and 2am Monday for Marlborough south of Seddon and Canterbury north of the Rangitata River.
Following the rain, an area of low pressure is expected to bring colder air to eastern parts of the South Island. Kiwis heading into the hills are advised to prepare for the possibility of snow, with forecasts indicating snow could fall as low as 1200 metres.
North Island to Experience Muggy Conditions
Meanwhile, the North Island is bracing for a different kind of weather. A tropical low travelling from Fiji is expected to bring moist, hot air, resulting in muggy conditions. Auckland is forecast to reach a high of 29C tomorrow, nearing the threshold for a heat alert. Similar temperatures are expected in Whenuapai and Whangārei.
A MetService spokesperson explained that warm air over the cold sea in inshore areas will likely create seafog, potentially extending inland and exacerbating the muggy temperatures.
Southerly winds are also anticipated near the Cook Strait on Tuesday, though MetService indicates a low probability of these winds becoming strong enough to warrant a warning for the Marlborough Sounds, Wellington, and southern Wairarapa. The risk of thunderstorms across the country is currently assessed as low.
