MetService meteorologist John Law said while it looked like another clear, cold night again tonight temperatures were set to be milder from Friday night onwards.
“Unfortunately, this coincides with the return of some wetter weather as we head into the end of the week. There is currently a heavy rain warning for the Coromandel from 4pm Friday to 9am Saturday and we may find some heavy rain into the western parts of the Bay of Plenty for Saturday.”
A few showers were forecast for Rotorua on Saturday.
Police warning
Bay of Plenty road policing supervisor Sergeant Russell Owen also urged motorists to be cautious on the roads .
“With temperatures dropping we are seeing an increase in ice on our roads, low visibility, rain, and shorter days causing sunstrike.
“These conditions increase the risk of crashes if motorists fail to adapt to the driving conditions. Police are asking motorists to slow down and expect your travels to take longer,” Owen said.
He urged motorists to watch out for tiredness and fatigue and plan journeys accordingly.
“Our staff will be highly visible in the coming months and will be taking a zero-tolerance approach to speeding and dangerous driving behaviours.”
Police encouraged the public to report poor driving behaviour on 111 for emergencies or *555 and 105 for non-life-threatening matters.
