A warning has been extended to drivers in the lower North Island by the police to take care in wet conditions tonight while a keen watch is being kept by the local authorities for flooding.
Caution has been advised on State Highway 2, the Rimutaka Hill road, due to high winds and surface flooding, by police in the Wellington region. Problems have increased on the Hutt Road at Kaiwharawhara, near Wellington due to more surface flooding.
A slip partially blocked State Highway 1, north of Wellington earlier today.
Some delays were caused by the slip, affecting the southbound lane of the highway on the southern outskirts of Paekakariki, 41km north of Wellington, however it was cleared soon.
Authorities were on alert in Wanganui and Palmerston North, where there was surface flooding on Tuesday; however they are not expecting any dramatic developments.
It was confirmed by a Palmerston North City Council spokesman that while there would possibly be minor surface flooding, most rain was expected to fall in the Tararua Ranges.
There had been relatively less rainfall in Wanganui than forecast and no serious problems were anticipated.
A spokesman said, "The council will continue to monitor the situation and staff will be on call to respond if the situation changes."
