Tairāwhiti Civil Defence warns that State Highway 35 could be closed because of the rain as 20 roads remain closed after last week’s ex-cyclone Hale activity.
Speed restrictions are also in place on the highway and patrols and inspectors will monitor the highway as the downpours hit.
“At this stage it’s the saturated ground and vulnerable road network that are the main concern.
“Be prepared for temporary closures between Tolaga Bay and Ruatoria.
“Roads in Uawa are in a state with lots of silt and debris. Further rain could remobilise the silt back onto some roads.”
It said staff are continuing to monitor the forecast peak rainfall intensities for the Hikuwai River, which is predicted to reach 5m.
While wastewater emergency scours were all closed and discharges into the city’s rivers have stopped, Civil Defence is warning that the network is still running high and it won’t take much rain to trigger overflows.
“It’s a watch and see, but all agencies are prepared. We hope you are too, with supplies for at least three days.”
