Wind and rain are hitting New Zealand as a changeable spring weather pattern sets in across the country.
Kiwis were earlier warned about the "active weather" lashing the country this week - and now it is moving in.
There is a "high risk" of thunderstorms on Tuesday morning in Westland, Fiordland, and the coast of Southland, MetService said.
"The atmosphere will be pretty unstable tomorrow, especially over Te Waipounamu/South Island."
Along with thunder, rain is on the way along with snow. MetService said after the low-pressure system passes over New Zealand today, it drags up cold air from the south.
"This could bring snow as low as 300m in the far south with road snowfall warnings in force for many of the alpine passes over the South Island," they said.
Current road snowfall warnings are in place for Tuesday on Lewis Pass, Arthur's Pass, Porters Pass, Lindis Pass, Crown Range Road, and Milford Road.
To top it all off, high winds in Auckland have meant Waka Kotahi NZ Transport Agency has enforced reduced speed limits on the Harbour Bridge. Caution is advised, especially for high-sided vehicles and motorcycles, they added, and lane closures may be needed.
The "changeable spring weather pattern" is setting in across New Zealand and Australia, WeatherWatch said, and this week more low pressure will impact both countries and bring localised wind and rain.
"The North Island is most exposed to rain and wind this week, while the South Island is more exposed to a wintry cold snap, then some frosty weather," they said.
"By this weekend a storm south of Australia will be driving in wind and rain to [South Australia], [Victoria] and [Tasmania], while a low near NZ's upper North Island will also bring localised areas of heavy rain and wind this coming weekend."
