Auckland Transport is urging drivers to be careful on the roads with heavy rain and severe gales on the forecast tonight.
MetService meteorologist Emma Blades said the worst of the stormy weather was expected to hit Auckland later this evening and early on Tuesday.
Winds could gust up to 100km/h in exposed places and rain was expected to get heavy.
The weather will hit after the first rain band which is currently sweeping the city eases off, she said.
"If you get those localised downpours that could probably cause surface flooding for areas. In addition to that we've got strong northeasterly gales," she said.
"The heaviest stuff is from late evening so hopefully it will ease off a bit before that, when people are going home from work."
There was a watch in Auckland for the heavy rain and gales from tonight and the stormy weather should ease on Tuesday, she said.
Heavy rain could cause localised flooding on roads and low-lying areas such as Tamaki Drive could be affected by waves and surface flooding, an Auckland Transport spokesman said.
Heavy winds were also expected.
Auckland Harbourmaster Andrew Hayton said boaties should take the opportunity to secure moorings before the bad weather strikes.
They should not go out once the sea and wind conditions deteriorate, he said.
