Moist winds to bring rain this coming week
MetService advises that a front is forecast to approach New Zealand from the southwest on Monday and become slow moving to the south of the South Island on Tuesday.
“Also, on Tuesday a low is forecast to deepen over the Tasman Sea and slowly move towards New Zealand during Wednesday and Thursday,” says a MetService spokesperson.
“These weather systems are expected to maintain strong and moist north to northwest winds across much of central and southern New Zealand throughout the outlook period bringing periods of heavy
rain to the South Island west coast.
“There is high confidence of warning amounts of rain in Fiordland about and north of Doubtful Sound and Westland from Monday through to Wednesday, then the confidence reduces to low on Thursday.”
Heavy rain is also expected to spread across the main divide on Monday and Tuesday.
“There is moderate confidence of warning amounts of rain about the headwaters of Canterbury and Otago lakes and rivers. For Fiordland south of Doubtful Sound, there is low confidence of warning amounts of rain on Monday, then the confidence increases to moderate from Tuesday to Thursday. Meanwhile, there is low confidence of warning amounts of rain in Buller, Nelson west of Motueka as well as about the Nelson Lakes,” says a MetService spokesperson.
“Additionally, there is high confidence that north to northwest winds will approach severe gale in exposed parts of Fiordland, western Southland and the Stewart Island on Monday and Tuesday, then the confidence reduces to low on Wednesday. For the remainder of Southland, Otago, Canterbury and Marlborough south of Ward there is moderate confidence that north to northwest winds will
approach severe gale in exposed places from Monday through to early Wednesday.”
