It rained heavily in Auckland on Thursday morning and more rain is likely for this weekend's triathlon Grand Final - with showers predicted for Sunday's men's race.
The course is already arguably the toughest in the World Series, and any wet weather will make it even harder on the gruelling and very hilly bike leg.
But the country's notoriously fickle spring conditions could help the local athletes, who are more used to it.
Christchurch's Andrea Hewitt says the foreign athletes become more cautious on a wet track and any rain could put them off.
Hewitt says the tough conditions can scare the women and while she isn't hoping for rain, if it comes she'll just try to stay upright.
The elite women race on Saturday from just after a quarter past noon. The men race just after 1pm Sunday.
