Surface flooding has hit Invercargill as the South braces for a barrage of heavy rain, wind and snow.

Heavy rain is forecast throughout the South today as a major front makes its way up the country.
Further north near Makarora, Muddy Creek has flooded on to State Highway 6, covering the road in earth and debris.
